Periodic Table Vocabulary PRACTICE

Atoms of the same element (for example all Carbon) but they have different numbers of neutrons.

• nucleus

• isotope

• proton

• electron

We can draw an atom using this structure, which shows the chemical symbol and valence electrons of an element.

NGSS.MS-PS1-1

The total mass of an atom. We can find this by adding protons and neutrons.

• Electrons

• Mass Number

• Atomic Number

They are shiny, solid and good conductors of heat and electricity. Most elements are these.

• metalloids

• halogens

• metals

• noble gases

NGSS.MS-PS3-3

they are between metals and nonmetals on the periodic table. They have properties of metals and nonmetals.

• metals

• halogens

• metalloids

• alkali metals

They are located in the nucleus. They are neutral (do not have a charge).

• protons

• neutrons

• electrons

These are the elements of group 8A of the periodic table. They are unreactive. These are the "happy" atoms. :)

• halogens

• noble gases

• metals

• nonmetals

They are brittle, do not conduct heat or electricity and can be liquid or solid.

• metal

• halogens

• nonmetal

• noble gases

This is in the center of the atom. It contains the protons and neutrons.

• atom

• proton

• neutrons

• nucleus

This is an organized set of all of the known elements in the world.
