Atomic structure- main focuses- part 2

Question 1

What are group 1 metals?

Answer 1

Elements that have one electron in their outer shell which makes them very reactive

Question 2

What happens as you move down group one?

Answer 2

1) increasing reactivity
2) lower melting and boiling points
3) higher relative mass

Question 3

What are properties of group 1 metals?

Answer 3

1) soft

2) low density

Question 4

What happens when group 1 reacts with

1) water
2) chlorine
3) oxygen

Answer 4

1) water- react vigorously to produce hydrogen gas and metal hydroxide
2) chlorine- react vigorously when heated in chlorine to form metal chloride salts
3) oxygen- forms metal oxide

Question 5

What is group 7 known as?

Answer 5

Halogens

Question 6

What happens as you move down group 7?

Answer 6

1) Less reactive
2) higher melting and boiling points
3) higher relative atomic mass

Question 7

How do halogens form molecular compounds?

Answer 7

Halogens can share electrons via covalent bonding with other non-metals to achieve a full outer shell, forming molecular compounds

Question 8

What do halogens form when they bond with a metal?

Answer 8

1- ions called halides

Question 9

What is a displacement reaction?

Answer 9

Occurs when a more reactive halogen displaces a less reactive one

Question 10

What are all group 0 elements?

Answer 10

Colourless gases which are very unreactive because they have a full outer shell

Question 11

What are group 0 elemental also known as?

Answer 11

Nobel gases

Question 12

What happenes as you move down group 0?

Answer 12

Boiling point increases along with relative atomic mass
