A
Show repeating trends in physical and chemical properties
1
Q
Periodicity definition
A
A repeating pattern across different periods
2
Q
Elements in the same group…
A
Have similar outer-shell electron configurations, resulting in similar physical and chemical properties
3
Q
Describe and explain the trend in melting and boiling point for period 2 and period 3 elements
A
The melting and boiling points of the metals in period 2 and 3 increase along the period
This is because the ionic charge increases (as the nuclear charge increases), so the ionic size decreases. As you go along the period, the charge increases. So as you go along the period the charge density increases
