bonding and structures 1.2

Question 1

how are covalent bonds made

Answer 1

when two or more non-metal atoms share electrons to achieve a full outer shell

Question 2

how are ionic bonds formed

Answer 2

when metal atoms give electrons to a non-metal atom and oppositely charged ions are formed

Question 3

Answer 5

group 8

noble gases

Question 6

prefixes

Answer 6

Mono-1
Di-2
Tri-3
Tetra-4
Penta-5
Hexa-6

Question 7

what is meant by the term diatomic element

Answer 7

a covalent molecule containing just two atoms

Question 8

do covalent network and covalent molecular conduct electricity

Answer 8

no, not in any state because there are no charged particles

Question 9

why do ionic compounds conduct when molten or in solution

Answer 9

because the ions are free to move
