Neutrons have a neutral charge
Neutrons have no charge.

Elements like barium located toward the bottom of a group have a lower attraction for their valence electrons because they have a

large atomic radius.
large atomic radius.

Elements that typically take electrons

are nonmetals, include the halogens

Which atoms have the lowest electronegativity

Atoms to the left on the periodic table

Atoms with a large atomic radius

The of a sound wave deals with the volume of the sound

amplitude

States of matter depend in part on the of an item

temperature

All atoms and molecules have mass and are therefore

Therefore they are consider matter. Remember anything with a mass is matter.

How many main groups in the modern periodic table of elements are there

There are 18 main groups in the modern periodic table of elements.

The atomic radius as you move from left to right on the periodic table

it is Decreases

Atoms with a low ionization energy hold tight to their outer valence electrons

No; the phrase given characterizes high rather than low ionization.

What does electronegativity represent why does it increase left to right and top to bottom on the periodic table

electronegativity represents the size of an atom

What group of elements has seven valence electrons

The Halogens have seven valence electrons.
