It is a trend in itself, it isn't caused by a trend.
The atonic radius decreases as you go left across the periodic table because of the increased positive charge in the nucleus.
The ionization energy increases going across a periodic table.This is because of increasing nuclear charge.
Ionization energy increases as we go across a period. Its value decreases as we go down a group.
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.
Helium (He) has the highest ionization energy.
As you go from right to left in a period in the periodic table the ionization energy increases. While going from top to bottom in a group in the periodic table the ionization energy decreases .
The ionization energy increases going across a periodic table.This is because of increasing nuclear charge.
Across a row on the periodic table ionization energy increases. Down a column, ionization energy decreases. --------------------------------------------------------- The first Ionization energy of Boron is 800.6 kJ mol-1
Ionization energy generally increases across a period as a result of a higher nuclear charge, however there are some exceptions such as Boron which has a lower ionization energy than Beryllium (because it is in a P orbital), and Oxygen which has a lower ionization energy than nitrogen (Because ionization decreases the electron electron repulsion in its orbitals).
ionization energy
When moving left to right across the PT the ionization energy increases. As you go down, the ionization energy, decreases.
Ionization energy increases as we go across a period. Its value decreases as we go down a group.
The correct answer is: The ionization energy increases because there are more protons to pull on the electrons.
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.
The correct answer is: The ionization energy increases because there are more protons to pull on the electrons.
In a group the first ionization energy decrease going down.In a period the first ionization energy increase from left to right.
