The atomic number tells you what?

both electrons and protons in an atom.

Atoms with similar properties are most likely located...

to the right and left of each other.

As you move down a group, atomic radius increases because -

you add more and more shells (energy levels)

As you move across the periodic table from left to right, the atomic radius decreases. This is because -

the number of protons increases, so attraction to electrons increases

the number of energy levels increases

the number of electrons increases

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

Electronegativity is...

the ability of an atom to attract/ accept 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.

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

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.

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.

Which of the following is true for alkaline earth metals as their atomic number increases?

The number of valence electrons increases.

The Coulombic attraction increases.
