Why the 1st ionic energy increase across period 2?
Because as the nuclear charge increases, the attraction between the nucleus and the electrons increases and it requires more energy to remove the outermost electron and that means there is a higher ionization energy. As you go across the periodic table, nuclear charge is the most important consideration. So, going across the periodic table, there should be an increase in ionization energy because of the increasing nuclear charge.
Does nuclear charge increases as you move from left to right across the periodic table?
moving from left to right across a period, one electron is added for each element.example: Boron has 3, Carbon has 4.
What happens when the nuclear charge increases across a period?
The atomic size decreases (with some exceptions) , the ionization energy , electronegativity and electron affinity also increase from left to right.
Why does size of an atom decrease across the period?
as you go from left to right across the periodic table, you are adding one more proton every time hence increasing the nuclear charge of the atom. An increased nuclear charge means the nucleus attracts the electrons more to it hence the size of the atom decreases as it "tightens". hence the atomic radius decreases every time.
Do valence electrons increase or decrease across the row of tables?
They increase from left to right.

Why does the first ionization energy increase as you go across a period?
Because as the nuclear charge increases, the attraction between the nucleus and the electrons increases and it requires more energy to remove the outermost electron and that means there is a higher ionization energy.

Where were the prisoners during the holocaust prisoned?
there were camps across occupied Europe.
Why do atom size decreases in periods instead of increasing due to protonic repulsion?
As we move across the period, there is an increase in the atomic number i.e., there is an increase in the number of protons inside the nucleus. This means, there is more nuclear force. This nuclear force pulls the electron orbits as close as it can. thus, the radius of the atom decreases. Hence the atomic size decreases.
Why do the atomic size decreases in periods rather than to be increased due to proton repulsion that leads to nucleus to expansion?

Was Campaign for Nuclear Disarmament been successful at achieving their aims?
The Campaign for Nuclear Disarmament (CND) has made significant progress in raising awareness about nuclear weapons and advocating for their elimination. While they have not achieved complete disarmament, their efforts have contributed to international discussions on nuclear non-proliferation and disarmament. The organization continues to work towards its goal of a world free of nuclear weapons.
How is a dirty nuclear bomb detonated?
A dirty nuclear bomb is detonated by using a conventional explosive. It disperses a large amount of nuclear material across the area.
What are some examples of nucleus envelope?
Nuclear envelope is a boundary that separates nuclear materials from the cytoplasm. Nuclear envelope possess proteins to exchange molecules across the nuclear membranes such as importins/exportins.
Do valence electrons increase or decrease across the row of tables?
They increase from left to right.
