bonding

Question 1

ionic bonding happens between

Answer 1

non metal and metal

Question 2

covalent bonding happens between

Answer 2

2 non metals

Question 3

how much energy is needed to overcome intermolecular forces

Answer 3

not a lot of energy

Question 4

properties of ionic bonding

Answer 4

opposite charge ions attract
form a giant ionic lattice
brittle
soluble in water

Question 5

electrostatic attractions

Answer 5

oppositely charged ions

Question 6

simple covalant bond

Answer 6

not much energy is needed to overcome to weak intermolecular forces of attrition between molecules

Question 7

giant covalent bond

Answer 7

many covalent bonds need to be broken

a lot of energy is needed tp break their bonds

Question 8

metallic bonding properties

Answer 8

postive ions are surrounded by a sea of delocalised electrons
free electrons are able to move through structures so metals can conduct electricity and heat
layers of ions in metal can slide over each other making them malleable
The electrostatic attractions between nuclei of the positive ions and the eleltrons is called metallic boding

Question 9

Electronic Configuration

Answer 9

How electrons are arranged in the shells in an atom.

Question 10

Periodic Table arrangement

Answer 10

Table in which elements are arranged in order of increasing atomic number (and in terms of chemical and physical properties)

Question 11

covalent bond meaning

Answer 11

OR

M1 bonding/shared pair(s) of electrons M2 attracted to nuclei (of both atoms)

Question 12

explain why ionic bond has high melting point

Answer 12

M1 has giant (ionic structure)/giant (ionic lattice) M2 strong (electrostatic) forces/strong attraction M3 between (oppositely charged) ions
M4 large amount of (thermal/heat) energy required to overcome the forces/attraction
