Answer:
A》. diatomic atom is composed of only two atoms, of the same or different chemical elements. Examples of diatomic molecules are O2 and CO. ... There are seven diatomiceElements: Hydrogen (H2), Nitrogen (N2), Oxygen ( O2), Fluorine ( (F2), Chlorine ( (Cl2), --Iodine ( (I2) and Bromine (Br2) .
B》Polyatomic atoms are the group of atoms that have a net charge on them.
Hence ions are charged particles .
Example :
Sulphate ion --- SO4⁻²
sulphate ion contains atoms of sulphur and oxygen atoms with a net charge of -2.
Carbonate Ion -- CO3⁻²
C》 Helium.
Radon.
D》 Alkali metals are elements with valency 1. Examples include lithium (Li), sodium (Na), potassium (K), rubidium (Rb) and caesium (Cs). Thus, one atom of sodium ...
E》 Cations can be formed from metal elements, as well as nonmetal elements. If a metal element forms an ion, it always forms a cation. Some metals always form the same type of cation. For example, sodium always forms a +1 cation and magnesium always forms a +2 cation.
