Atomic Radius, Ionization Energy, and Electronegativity

As you move from top to bottom down a group on the periodic table the size of atom will ____

get bigger

This happens because as you move down the group each element has one more occupied ____than the last one

orbital

As you move from left to right across a period on the periodic table the size of the atom will ____

get smaller

This happens because as you move across a period each element has one more ____ in its nucleus than the last one

proton

Within a period the elements will have the same number of occupied ____

orbitals

Why does F have a smaller atomic radius than O?

F has a larger number of protons

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

ionization energy

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

decrease

This is because the electrons are ____ attracted to the nucleus as they get further away from the nucleus

less

The ionization energy of the elements will ____ as you move from left to right across a period on the periodic table

increase

This is because the electrons are all the same distance from the nucleus in the same period, but the elements have ____ protons as you move from left to right across the periodic table

more

The size of a positive ion is always ____ than the size of the neutral atom of the same element

smaller

As the positive charge on an ion increases , the size of the atom will ____

decrease

The size of a negative ion is always ____ than the size of the neutral atom of the same elements

larger

AS the negative charge on an ion increases, the size of the atom will ____

increase

____ is the tendency for the atoms of the element to attract electrons when they are chemically combined with another element

Electronegativity

As you move across a period from left to right the electronegativity of an element will ____

increase

As you move down a group, the electronegativity of an element will ____

decrease
