(b) Positively charged ions

plz

​

Answer 1

Answer:

1.FE(iron)

AL (aluminum)

Co(cobalt)

AG ( silver)

NA ( sodium)

2... any atom or group of atoms that bears one or more positive or negative electrical charge are ions. The ions containing positive charge is called cation and having negative charge is called anion

divalent cation - Mg^2+(magnesium)

divalent anion- O^2-(oxide).

3..(..a)the Atomicity of sulfur is 8.

(b) the Atomicity of phosphorus is 4

4...(a).GROUP OF ATOMS CARRYING A CHARGE ARE CALLED POLYATIMIC IONS .
