What else can I help you with?
What is the trend in period 2 ionization energy across the elements?
The trend in period 2 ionization energy across the elements increases from left to right.
What element deviates from the trend in ionisation energy across period 2?
Nitrogen deviates from the trend in ionization energy across period 2. It has a higher ionization energy than oxygen, which would be expected based on the trend of increasing ionization energy from left to right in a period. This anomaly is due to the half-filled electron configuration of nitrogen's outer energy level, making it more stable.
What is the exception to the trend of increasing ionization energy across a period in the periodic table?
The exception to the trend of increasing ionization energy across a period in the periodic table occurs when transitioning from group 2 to group 3 elements. This is because the group 3 elements have a slightly lower ionization energy compared to the group 2 elements due to the added stability of having a half-filled or fully-filled subshell.
Is the trend across a period similar or different for periods 2 3 4 and 5?
Similar for they have the same number of electrons in the last shell
What period is boron?
Boron is a non-metallic element on the periodic table and belongs to period 2.
What is the trend in period 2 ionization energy across the elements?
The trend in period 2 ionization energy across the elements increases from left to right.
Why does the change for the atomic radii of the elements for period 3 from sodium to argon look similar to period 2?
Because the trend is the same. Atomic radius decreases from left to right across a period.

This anomaly is due to the half-filled electron configuration of nitrogen's outer energy level, making it more stable.
Why does the change for the atomic radii of elements in period 3 from sodium to argon look similar to period 2?
The atomic radii of elements in period 3 from sodium to argon decrease due to a greater nuclear charge pulling electrons closer to the nucleus. This trend is similar to period 2 because both periods follow the same pattern of increasing nuclear charge as you move across the period, leading to a similar decrease in atomic radii.
Is a trend across a period similar or different for periods 2 3 4 and 5?
Similar for they have the same number of electrons in the last shell
What was the effect on peoples diet in World War 2?
As a general trend, people ate less, since World War 2 was the first instance of rationing in US History.
Can you describe the general trend in atomic radius in group 2A?
In the group 2 (IUPAC name) of the periodic table the atomic radius increase from beryllium to radium.
Do any 2 solids have the same densities?
They do if they are the same material

Does an element on the periodic table decrease in atomic size when you move across a period from left to right and when you move down a group?
1. In a period is a trend of decrease from left to right but it is not absolute.2. In a group the atomic radius increase moving down.
What 2 things have extraordinarily large densities?
'Black holes' and neutron stars.
