The atomic number tells you what?

both electrons and protons in an atom.

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

The atoms have more energy levels

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

Metals have the largest -

atomic radius and electronegativity

electronegativity and ionization energy

ionization energy and atomic radius

Which statement correctly and completely identifies a trend?

Atomic radius decreases across a period and increases down a group.

Electronegativity decreases across a period and decreases down a group.

Ionization energy increases across a period and increases down a group.

Ionic radius increases across a period and increases down a group.

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

Francium (Fr) has the lowest ionization energy in Group 1 because -

its 1 valence electron is very far from the nucleus, so little energy is needed to remove it

it has the smallest number of valence electrons

it has the greatest atomic mass

it has the greatest number of protons, so it attracts its electrons the strongest

The elements chromium (Cr) and zinc (Zn) are in period four of the periodic table. Which characteristic of zinc and chromium is correct based on their positions?

Chromium has lower ionization energy than zinc

Zinc has a greater atomic radius than chromium

Zinc loses electrons more easily than chromium

Chromium has more valence electrons than zinc

Elements Z and X are compared. Element Z is larger than Element X. Based on this you could say:

Element Z is further to the left side of the periodic table

Element X is closer to the top of the periodic table

Element Z and X are probably in the same group

As the atoms in period 3 of the periodic table are considered from left to right, the atoms generally show...

a decrease in radius and an increase in ionization energy

an increase in radius and an increase in ionization energy

an increase in radius and a decrease in ionization energy

a decrease in radius and a decrease in ionization energy

Which of the following factors contributes to the higher ionization energy of the lower atomic number elements in a family on the periodic table?

Shorter distance from nucleus; shielding
