First ionization increases because in an atom when we remove first electron of the atom it can be removed easily while as we move to second electron it can't be remove easily because second electron is more near to nucleus and it faces more force of attraction than first one.
What else can I help you with?
What is the general trend of ionization energy as you go across the periodic table?
Across a period, first ionization energy increases. However, when going down a group, first ionization energy generally decreases. As you go down a group, atoms hove more total electrons so they don't really care that much about their outermost ones.
As you go from left to right across a period the first ionization energy generally decreases or increases?
increases.
What happens to first ionization energy within groups and periods?
it increases. the nuclear charge also increases
Does the first ionization energy increase or decrease when you go down a group?
it increases
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
What is the general trend in first ionization energy?
increases from left to right across a period.
Which element in the fifth period has the highest ionization energy?
The element in the fifth period with the highest ionization energy is xenon. Ionization energy generally increases across a period from left to right, so xenon, being on the far right of the period, has the highest ionization energy.
How does the first ionization energy change going down and across the periodic table?
As you move down a group on the periodic table, the first ionization energy generally decreases due to the increasing atomic size and shielding effect of inner electrons. Across a period, the first ionization energy generally increases because the effective nuclear charge increases, making it harder to remove an electron.
Describe the trends in first ionization energy within groups and across periods in the periodic table Provide examples?
Within a group, first ionization energy generally decreases as you move down the group due to increasing atomic size and shielding effects. Across a period, first ionization energy generally increases due to increasing nuclear charge and effective nuclear charge. For example, within Group 2 (alkaline earth metals), the first ionization energy decreases as you move down the group from Be to Ra. Across Period 3, the first ionization energy increases from Na to Cl.
What trend it does the first ionization energy follow going across the periodic table?
The first ionization energy tends to increase across a period from left to right on the periodic table. This is due to the increasing nuclear charge and decreasing atomic radius, which leads to a stronger attraction between the electrons and the nucleus.
What trends does the first ionization energy follow going across the periodic table?
The correct answer is: The ionization energy increases because there are more protons to pull on the electrons.
