NGSS.HS-PS1-8

A subatomic particle of about the same mass as a proton but WITHOUT an electric charge, present in all atomic nuclei except those of ordinary hydrogen.

• Neutron
• Nucleus
• Proton
• Atom

A stable subatomic particle with a charge of NEGATIVE electricity, found in all atoms and acting as the primary carrier of electricity in solids.

• Electron
• Proton
• Neutron
• Nucleus

The number of protons in the nucleus of an atom, which determines the chemical properties of an element and its place in the periodic table.

• Atomic number
• Mass number
• Group/Family
• Reactivity

An abbreviation or short representation of a chemical element; the symbols in the periodic table.

• Chemical Symbol
• Periodic Table
• Malleable
• Luster

The name given to a horizontal row of the periodic table. The periodic table has seven. 

• Period
• Group/Family
• Magnetism
• Molecule

A table of the chemical elements arranged in order of atomic number, usually in rows, so that elements with similar atomic structure (and hence similar chemical properties) appear in vertical columns.

• Periodic Table
• Chemical Symbol
• Period
• Conductivity

 A column of elements in the periodic table of the chemical elements. There are 18 numbered.

• Group/Family
• Ductile
• Period
• Metal

Elements that form cations when compounds of it are in solution and oxides of the elements form hydroxides rather than acids in water. Most are conductors of electricity, have crystalline solids with a metallic luster and have a high chemical reactivity.
