Astudent repeated the experiment with a different group 2 metal carbonate (xco3).
the relative formula mass (m.) of xco, is 84
relative atomic masses (a):
c = 12
0 = 16
calculate the relative atomic mass (ar) of x.
name metal x.
use the periodic table.

a plasma is a warm ionized gasoline consisting of approximately equal numbers of definitely charged ions and negatively charged electrons. the characteristics of plasmas are notably unique from the ones of ordinary neutral gases in order that plasmas are considered a awesome "fourth kingdom of remember."

the number of valence electrons for each molecule or ion is shown beneath the structure. remember hydrogen will not have more than two electrons. this hydrogen is part of a covalent bond (sharing two electrons). a double bond here would cause hydrogen to share four electrons with phosphorus.
