1.37-1.43 ionic bonding

Question 1

what is an ion and how is one formed

Answer 1

an ion is a charged atom

its formed when an atom gains or loses electrons from the outermost energy shell

Question 2

what are the charges of groups 1,2,3,5,6,7

Answer 2

1. 1+
2. 2+
3. 3+
4. (ignored)
5. 3-
6. 2-
7. 1-

Question 3

what are ionic compounds

Answer 3

Metals transfer Electrons to Non - Metals

Question 4

what is the formulae for metals and non metals for compounds formed between ions

Answer 4

METALS: Loses Electrons to another atom and become Positively Charged Ions

NON - METALS: Gains Electrons from another atom to become Negatively Charged Ions

Question 5

describe ionic bonding in terms of electrostatic attractions

Answer 5

a strong electrostatic attraction between oppositely charged ions.

Question 6

why do ionic compounds have high melting and boiling points

Answer 6

they have a giant structure with strong electrostatic forces between oppositely charged ions that require a lot of energy to break.

Question 7

when do ionic compounds conduct electricity

Answer 7

ionic compounds conduct electricity when molten or in solution
