Periodic table groups

Question 1

What happens to the reactivity as you go down group 1?

Answer 1

• Reactivity increases
• Atomic size increases so furthest electron gets further away. So electrostatic force of attraction between positive nucleus and negative electron gets weaker and outer electron lost more easily

Question 2

What happens to MP and BP as you go down group 1?

Answer 2

• MP and BP decreases

Question 3

What happens to reactivity going down group 7?

Answer 3

• Reactivity decreases
• Atomic size increases so furthest shell gets further away and shells cause shielding. Therefore, harder for nucleus to attract another electron and gain 1 electron

Question 4

What happens to MP and BP going down group 7?

Answer 4

• MP and BP increases

Question 5

What happens to MP abd BP going down group 8?

Answer 5

• MP and BP increases
