Trends in the Periodic Table

Question 1

What is electronegativity?

Answer 1

The strength in which an atom (or ion) holds onto it’s outer electrons.

Question 2

How do we determine the electronegativity?

Answer 2

As you go to the right and higher^^ on the periodic table the electronegativity increases (the ability to hold onto outer atoms)

Question 3

What changes are noted when the atoms have stronger electronegativity?

Answer 3

As the electronegativity changes as does the reactivity.

Question 4

What happens to the zone of probability when the electronegativity is high?

Answer 4

The zone of probability (shells) is more congested as there is a higher pull force towards the centre of the atom.

Question 5

How do you explain the trends in the periodic table?

Answer 5

The more protons the greater the positive charge in the nucleus, the higher the electronegativity.

Question 6

As you travel to the right side of the table what happens to the atomic radius?

Answer 6

The atomic radius of the atoms gets smaller.
