3.3.1 - Ion Formation

Question 1

When forming METAL IONS metal atoms tend to…

Answer 1

. …Lose all of their outer-shell electrons to get a FULL OUTER-SHELL

-(therefore they become POSITIVELY CHARGED IONS and they are now MORE STABLE)

Question 2

Oxidation is…

Answer 2

. …The LOSS of electrons

Question 3

When forming NON-METAL Ions NON-METALS tend to…

Answer 3

. …gain electrons to fill their outer-shell

-(they therefore become NEGATIVELY CHARGED IONS and they are MORE STABLE)

Question 4

Reduction is…

Answer 4

. …the GAIN of electrons

Question 5

When forming IONIC COMPOUND…

Answer 5

. …metals and non-metals react, THE METAL AROMS GIVE ELECTRONS TO THE NON-METAL ATOMS

-(every atom ends up forming an ion with a stable full outer-shell)

Question 6

After electrons have been transferred from metal to non-metal what is formed !?

Answer 6

. Ions are formed

Question 7

Do Atoms in the same periodic table group gain/lose DIFFERENT numbers of electrons !?

Answer 7

. No, atoms in the SAME PERIODIC TABLE GREOUP gain/lose the SAME number of electrons.

Question 8

Do atoms in the same periodic table group form ions with the SAME charge !?

Answer 8

. Yes, atoms in the SAME periodic table group form ions with the SAME charge
