Trend across period 3
WebTrends in Group 2 Compounds. Group 2 Elements are called Alkali Earth Metals. They are called s-block elements because their highest energy electrons appear in the s subshell. Progressing down group 2, the atomic radius increases due to the extra shell of electrons for each element. Going down the group, the first ionisation energy decreases. WebThe general trend in ionisation energy across period 3 elements is that it increases with increasing nuclear charge. There are 2 "dips" in this trend, these are with the elements aluminium and sulfur. The 2 dips in the ionisation energies, one as we go from Mg to Al and the other as we go from the element P to S.

WebWhat is the trend in atomic radius of the elements across Period 3 and why does this occur? The atomic radius of the elements decreases from sodium to argon. This is because the number of protons increases (sodium has 11, argon has … Web- Trends across period 3: 13.2 - First-row d-block elements: 13.1 - Trends across period 3. Characteristic: Trend (left to right) Reason: Atomic radius: decreases in size from left to right: increased attractive force (acting on the same energy shell) from the nucleus as the number of protons (and hence the nuclear charge) increases : Ionic ...

Period - reactivity increases as you go from the left to the right. Group - reactivity decreases as you go down the group. WebIt shows the first ionisation energy of each of the elements in period 3. Fig. 3 - A graph showing the first ionisation energies of the elements in period 3. Note the upward trend. Overall it follows the trends described above - an increase in ionisation energy across the period as nuclear charge increases - but there are some exceptions.
