Chem trends in p table

Question 1

Atomic radius

Answer 1

Half the distance between nuclei of two atoms of the same element that are joined together by a single covalent bond

Question 2

Atomic radius down the period table

Answer 2

Increase
New energy level further from nucleus
Screening effect of inner electrons

Question 3

Atomic radius across periodic table

Answer 3

Decrease increase in effective nuclear charge no increase in screening effect

Question 4

First ionisation energy

Answer 4

Minimum energy require to completely remove to most loosely bound electron form a neutral gaseous atom in its ground state

Question 5

First ionisation energy values down p table

Answer 5

Decrease increasing atomic radius screening effect of inner electrons

Question 6

First ionisation energy values across p table

Answer 6

Increase increasing effective nuclear charge decreasing atomic radius
