What else can I help you with?
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.
Nuclear charge increases across a period atoms become?
The atoms become smaller in atomic radius.
What trend in ionization energy occurs across a period on the periodic table and why?
The ionisation energy increases across a period. Across a period, nuclear charge increases. The tendency to loose electron decreases.
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.
What has a a greater effect on atomic size nuclear charge across a period or increase occupied energy levels withen a group?
The increase in nuclear charge across a period has a greater effect on atomic size than the increase in occupied energy levels within a group. As you move across a period, the effective nuclear charge increases, pulling electrons closer to the nucleus and resulting in a decrease in atomic size. In contrast, while adding occupied energy levels down a group increases atomic size, the effect of increased nuclear charge across a period is more significant in reducing atomic radii. Thus, nuclear charge plays a more crucial role in determining atomic size within a period.
What happens to first ionization energy within groups and across periods?
it increases. the nuclear charge also increases
What happens to first ionization energy within groups across periods?
it increases. the nuclear charge also increases

Why nuclear charge increases when atomic number increases across a period?
As you move across a period, the atomic number increases because more protons are added to the nucleus. This increase in protons leads to a greater positive nuclear charge, as protons are positively charged particles. The increased nuclear charge exerts a stronger attraction on the electrons in the outermost energy level, resulting in a greater effective nuclear charge felt by those electrons.
Nuclear charge increases across a period atoms become?
The atoms become smaller in atomic radius.
What trend in ionization energy occurs across a period on the periodic table and why?
The ionisation energy increases across a period. Across a period, nuclear charge increases. The tendency to loose electron decreases.
What to atomic properties have an increasing trend as you move across the periodic table?
As we move across a period, electronegativity increases. Ionization enthalpy also increases because of increasing nuclear charge.
Is the effective nuclear charge directly related to electronegativity?
Yes, the effective nuclear charge is directly related to electronegativity. Electronegativity increases as the effective nuclear charge on an atom increases.
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.
What trend does electronegativity follow?
In electronegativity, the first ionization energy increases as it moves from left to right across a period . The nuclear charge also increases and the shielding effect is constant when moving across.
How does size change in a period and in a group?
Atomic size decreases across a period as the effective nuclear charge increases. Atomic size increases down a group as the energy level (shells) increases.
