Atomic number refers to the number of:

• protons in the nucleus

• neutrons in the nucleus

• electrons in the nucleus

• protons and neutrons combined

Isotopes of an element have the same:

• atomic number but different mass number

• mass number but different atomic number

• number of electrons but different number of protons

• number of protons but different number of neutrons

Elements in the same group of the periodic table have similar:

• atomic mass

• number of protons

• chemical properties

• physical appearance

The electron configuration of an atom describes the:

• arrangement of protons in the nucleus

• arrangement of neutrons in the nucleus

• arrangement of electrons in the energy levels

• arrangement of protons and neutrons in the nucleus

Elements in the same period of the periodic table have the same:

• number of electron shells

• number of protons

• chemical properties

• physical appearance

Ionic bonding occurs between:

• two metals

• two nonmetals

• a metal and a nonmetal

• two noble gases

Metals are generally:

• brittle

• dull

• non-conductive

• malleable

Acids are substances that:

• taste bitter

• turn blue litmus paper red

• feels slippery

• produce hydroxide ions (OH-) in solution

A neutralization reaction occurs between:

• an acid and a base

• two acids

• two bases

• a metal and a nonmetal

The flame test is used to identify elements based on the:

• colour of light emitted when heated

• mass of the element

• chemical reactivity of the element
