As you move down the periodic table atoms get bigger. This is because ____________.

The atoms have more energy levels

Electronegativity is...

how good an atom is at attracting electrons

the ability of an atom to lose electrons

the energy required to remove an electron from a specific atom

how easy it is to make friends.

Atomic radius generally increases as we move __________.

down a group and from right to left across a period

up a group and from left to right across a period

down a group and from left to right across a period

up a group and from right to left across a period

Who developed the Periodic Table?

Mendeleev, who was a chemist and teacher

Pavlov, who was a teacher and physchologist

Ladahoff, who was a teacher and biologist

Ionization energy is...

how much energy it takes to remove an electron from an atom

the energy required to add an electron to a specific atom

the energy required to shield the outer electrons from the nucleus

a measure of the ability of an atom to attract electrons

Lithium has a smaller atomic radius than potassium, explain why.

Lithium has less energy levels than potassium.

Lithium has more energy levels than potassium.

Lithium has more protons than potassium.

Potassium has a smaller atomic radius

Nitrogen has a smaller ionization energy than antimony. Explain why.

Nitrogen has less energy levels than antimony. Therefore, the electrons are close to the nucleus and it requires more energy to remove these electrons.

Nitrogen has more energy levels than antimony. Therefore, the electrons are farther from the nucleus and it requires more energy to remove these electrons.
