Front

What is Electronegativity?

Back

Electronegativity is how good an atom is at attracting electrons.

Front

Why does Francium (Fr) have the lowest ionization energy in Group 1?

Back

Francium has the lowest ionization energy because its 1 valence electron is very far from the nucleus, so little energy is needed to remove it.

Front

Is it true that the second ionization energy of any element is higher than its first ionization energy?

Back

True.

Front

What is the term for the energy released when an electron is attached to a neutral atom?

Back

Electron Affinity.

Front

How many valence electrons would an element have if there is a huge jump in the fifth ionization energy?

Back

4 valence electrons.

Front

What is Ionization Energy?

Back

Ionization Energy is the energy required to remove an electron from a specific atom.

Front

What trend is observed in electronegativity across a period?

Back

Electronegativity increases across a period from left to right.

Front

What trend is observed in ionization energy down a group?

Back

Ionization energy decreases down a group.

Front

Define Atomic Radius.

Back

Atomic Radius is the distance from the nucleus to the outermost electron shell.

Front

What is the relationship between atomic size and ionization energy?

Back

As atomic size increases, ionization energy decreases.
