Ionization Energy Trend

When an electron is removed the atom gets a ........ charge

• positive

• negative

Why are electrons held more tightly?

• Because of protons and requires more I.E. energy to move the electrons

• The closer is to the nucleus, the hardest to remove

Energy required to pull 1st electron away

• 1st I.E.

• 2nd I.E.

• 3rd I.E.

Requires more energy to remove .... and why

• 2nd energy because they are more attracted to a positive ion than to a neutral atom

• 1st energy

• 3rd energy because they are more attracted to a positive ion than to a neutral atom

The energy required to remove a second electron is called the ......

• 2 I.E. energy

• 3rd I.E. Energy

• 1st I.E. Energy

The energy required to remove an electron from a gaseous atom is called the ......

• Ionization energy

• Cation

• Anion

The ionization energy of the elements will ..... as you move down a group on the periodic table

• decrease

• increase

Energy required to pull 3rd electron away

• 1st I.E.

• 2nd I.E.

• 3rd I.E.

The energy required to remove an electron is always much, much greater if the atom is a ......... before the electron is removed.

• Noble gas

• positive

• negative

The ionization energy increase because the electrons are all the same distance from the nucleus in the same period, but the elements have ........ protons as you move from to right

• less

• more
