each element is listed in a specific location that make the atomic structure.
Most are combined with elements in ores
several are used as catalysts
substances that make reactions occur faster withought changing itself
Groups 1,2 and 13-18
A carbon group is a periodic table group consisting of carbon, silicon, germanium,tin, lead, and flerovium.
the first two members of group 16,oxygen and sulfur,are essential for life.
The chemical elements in group 13 .
All the element in group 17 are nonmetals except for astatine, which is a radioactive metalloid.
Alkaline Earth Metals
is denser and harder and has higher melting point than the alkali metal in the same period.
any of the gaseous elements helium, neon, argon, krypton, xenon, and radon, occupying Group 0 (18) of the periodic table. They were long believed to be totally unreactive but compounds of xenon, krypton, and radon are now known.
silver solids with low densities and low melting points.
Composed of iron ,cobalt, and nickle
Have magnetic properties
Part of the Transition Elements
Inner Transition Elements
soft metals that were once thought to be
can hold up to 18 electrons
can hold up to 8 electrons
can hold up to 32 electrons
can hold up to 2 electrons
electron dot diagram
is the type which generates two oppositely charged ions.
the metal loses electrons to become positetively charged cation, where as the non metal accepts those electron to become negatively negatively charged ion.
tend to high melting point and boiling point.
is the sharing of electron between atoms.
includes of sigma and pi orbitals, therefore covalent bonds leads to formation of single, double, triple and quandruple bonds.
