Bonding

Question 1

Bonding

Answer 1

only valence electrons involving bonding

Question 2

Covalent bonding

Answer 2

2 or more atoms w/unpaired electrons move towards each other so outer orbits overlap and electrons are shared

Question 3

naming convent bonds

Answer 3

H2O water NH3 ammonia CH4 methane

mono oi tri teta pent

Question 4

relative molecular mass

Answer 4

add relative atomic mass of all the atoms win/ compound

unit = atomic mass unit

Question 5

ionic bonding

Answer 5

atoms w/ unpaired electrons approach each other

one atom has much bigger electromagnetically than the other

Question 6

ionic compounds

Answer 6

all metals form cations

work out charge of an element by looking at the valence

Question 7

metallic bonding

Answer 7

a bond in which the nucleus of metal atoms are held together in a lattice surrounded by a sea of electrons

Question 8

lattice

Answer 8

nuclue atoms
rigid structure
good conductors
electrons that can move around
