As you go along the groups, you add one proton and one electron.
The more protons you add, the higher the positive charge in the nucleus gets.
Similarly, the more electrons you add, the more negative the shell of electrons gets.
With rising opposing charges in the nucleus and in the electrons, the electrons become more and more attracted to the nucleus, making the atom get smaller and more "tightly packed" in a way. Since the electrons are more attracted to the nucleus, it gets harder and harder to pull one of them away. So 1st ionization energy would increase as you go down a group.
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).
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.
The correct answer is: The ionization energy increases because there are more protons to pull on the electrons.
The correct answer is: The ionization energy increases because there are more protons to pull on the electrons.
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

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.

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.
Ionization energy is a periodic function of atomic number because it follows periodic trends in the periodic table. As you move across a period from left to right, ionization energy generally increases due to increasing nuclear charge. Similarly, as you move down a group, ionization energy generally decreases due to increasing atomic size. These trends repeat as you move through each period, making ionization energy a periodic function of atomic number.

Atomic number, ionization energy and electronegativity
Ionization energy increases as you move across the periodic table from left to right. This is because the number of protons in the nucleus increases, leading to a stronger attraction between the nucleus and the electrons, making it harder to remove an electron.
No, arsenic does not have the highest ionization energy. Ionization energy generally increases as you move across a period in the periodic table from left to right. In the case of arsenic, it is found in the 3rd period, so elements to the right of it, such as bromine, have higher ionization energies.
Carbon has the highest ionization energy in Group 4 of the periodic table. This is because as you move across a period from left to right, the ionization energy generally increases due to increase in effective nuclear charge. Among the elements in Group 4 (carbon, silicon, germanium, tin, lead), carbon has the highest ionization energy.
