Periods are in the periodic table is a horizontal row.
An atomic number is the number of protons in the nucleus of an atom, which is characteristic of a chemical element and determines its place in the periodic table.
A mass number is the total number of protons and neutrons in a nucleus. A mass number takes place on every element on the periodic table.

Alkaline Earth Metals
The Alkaline Earth Metals are another group in the periodic table containing elements like beryllium, magnesium, calcium, strontium, barium and radium.
The Alkali Metals are a group in the periodic table containing the chemical elements sodium, lithium, potassium, rubidium, francium and cesium.
The Noble Gases is another group in the periodic table, group 18 contains elements like helium, neon, argon, krypton, xenon and radon.
The Isotope is something on the periodic table, an isotope is an atom with a different number of neutrons, but the same number of protons and electrons.
A compound is a substance consisting of atoms or two or more different elements in definite joined by a chemical bonds into a molecule, in the periodic table.
Supersaturation is a solution because it is a homogenous mixture of two or more substances. Supersaturated is beyond saturation point, over how much it can be absorbed.
A substance incapable of being dissolved, to create a solution.
Saturation is a solution because it is a homogenous mixture of two or more substances. Saturated is holding as much moisture as possible.
Filtration is an example of homogenous mixture because particles are distributed uniformly when the two substances are separated.
Chromatography is an example of homogenous mixture because particles are distributed uniformly when the chemical mixtures are carried by a liquid or gas is separated into sections. When that happens the section of differential distribution of the solutes as they flow around or over a stationary liquid or solid phase.
A solute is an example of a homogeneous mixture because solute is the substance which is dissolved and the particles are distributed uniformly.
Both a Homogeneous and a Heterogeneous Mixture are mixtures because they are substances made by mixing other substances together.
Law of Conservation of Mass
The law of conservation of mass is that, in a closed or isolated technique, matter cannot be created or destroyed. Even when matter goes through a physical or chemical change, the total mass of matter always stays the exact same.
States of Matter
A solvent is a substance that dissolves a solute, causing in a solution and solvent is usually a liquid.
Liquid is a state of matter because matter is defined as one of the ways in which matter can interact with itself to form a homogeneous phase and the liquids particles are free flowing, meaning while a liquid has volume, it doesn’t have shape. Liquids contains of atoms that are linked by intermolecular bonds.
A soluble is able to be dissolved, especially in a liquid.
A solid is a state of matter because matter is defined as one of the ways in which matter can interact with itself to form a homogeneous phase and the particles are organized such that their shape and volume are fairly even. The parts of a solid manage to be packed together much closer than the particles in a gas or liquid.
Vapor is a substance in the gas phase at a tempertaure lower than its critical temperature.
Gas is a state of matter because matter is defined as one of the ways in which matter can interact with itself to form a homogeneous phase and the particles that have neither a defined volume nor defined shape.
Chemical changes occur when a substance combines with another to form a new substance.
Solubility is a chemical property referring to the ability for a given substance, the solute, to dissolve in a solvent.
They are changes are affecting the form of a chemical substance, but not its chemical composition.
Mass is a measure of the amount matter in an object.
Mass is measured bu using a balance comparing a known amount of matter to a unknown amount of matter. weight is measured on a scale.
They are used to describe matter with thing such as smell (odor), density, melting point and boiling points.
They are used to observe and describe
Neutrons are part of an atom, neutrons make up an atom and neutrons and protons are found in the nucleus of an atom.
Electrons are part of an atom, it is a negatively charged particle that spins around the outside of the nucleus.
The Nucleus is a part of an atom, it is the central part of most cells that contains genetic material and is enclosed in a membrane
Protons are part of an atom, they are found in the center of the nucleus of an atom along with neutrons.
Orbitals are in the atomic theory because an orbital is a mathematical function that defines the “wave” reaction of either one electron or multiple of electrons in an atom.
The Atomic Theory is the theory about how all matter is made up of tiny particles which are atoms.
Atoms are made up of particles.
An Exothermic reaction is an example of an energy effect. An exothermic reaction is a chemical reaction that releases energy by light or heat. Expressed in a chemical equation: reactants --> products + energy.
They are substances that take part in undergo change during a reaction.
They are species formed from chemical reactions.
It is the energy which must be provided to a chemical or nuclear system with potential reactants to result into a chemical reaction.
An Endothermic reaction is an example of an energy effect. An Endothermic reaction happens when the energy used to break in the reactants is greater than the energy given out when bonds are formed in the products. Meaning that an Endothermic reaction takes in energy.
Quantitative Data is a Scientific Method because Quantitative Data are measures of values or counts and are expressed as numbers. And because it’s a method to know more about science.
Qualitative data is a Scientific Method because it’s a method to know more about science. Qualitative data is information about qualities; information that can't actually be measured.
An Experiment is a Scientific Method because it’s a method to know more about science. An experiment is a scientific procedure to make a discovery, test a hypothesis, or prove an identified fact.
A Hypothesis is a Scientific Method because it’s a method to know more about science. A hypothesis is an idea or explanation that you then test through study and experimentation.
A theory is a Scientific Method because it’s a method to know more about science. A theory is a well-substantiated explanation.
An independent and dependent variable are Scientific Method because it’s a method to know more about science. An independent variable is the variable that is changed in a scientific experiment to experiment the effects on the dependent variable. A dependent variable is the variable being tested and measured in a scientific experiment.
It is energy stored in the bonds of chemical compounds.
A solution in chemistry is a homogenous mixture of two or more substances.
Elements are each of more than 1hundred substances that can't be chemically interconverted or broken down into simpler substances and are primary constituents of matter.
