1. proton—

a. particles with no charge that exists in the nucleus of most atoms.

1. neutron -

b. center of the atom, contains most of the atoms mass.

1. electron—

c. positively charged particle in the nucleus of the atom. determines the element.

1. nucleus—

d. the smallest part of an element or molecule. building block of all things.

1. atom—

e. negative particles in the nucleus of the atom.
f negatively charged particle that exists in the space around the nucleus.

1. atomic number—

a. total number of protons and neutrons in the nucleus of an atom.

1. molecule—

b. number of protons in an atom; also the way the elements are numbered.

1. compound—

c. an atom with a different number of neutrons

1. mass number

d. two or more elements combined.

1. isotope—

e. two or more atoms that are combined (can be same two atoms of same element).
f number of electrons in an atom.

Explanation:

Step1: Recall element - symbol pairs

Gold has symbol Au, Fluorine has symbol F, Sulfur has symbol S.

Step2: Recall symbol - element name pairs

Mg is Magnesium, N is Nitrogen, He is Helium.

Step3: Recall atomic numbers

Oxygen has atomic number 8, B (Boron) has atomic number 5, Lithium has atomic number 3.

Step4: Recall atomic masses

H (Hydrogen) has atomic mass approximately 1.01 amu, Neon has atomic mass approximately 20.18 amu, Al (Aluminum) has atomic mass approximately 26.98 amu.

Step5: Match particle - description pairs

Proton - Positively charged particle in the nucleus of the atom. Determines the element (c).
Neutron - Particles with no charge that exists in the nucleus of most atoms (a).
Electron - Negatively charged particle that exists in the space around the nucleus (f).
Nucleus - Center of the atom, contains most of the atom's mass (b).
Atom - The smallest part of an element or molecule. Building block of all things (d).

Step6: Match atomic - concept - description pairs

Atomic Number - Number of protons in an atom; also the way the elements are numbered (b).
Molecule - Two or more atoms that are combined (can be same two atoms of same element) (e).
Compound - Two or more elements combined (d).
Mass Number - Total number of protons and neutrons in the nucleus of an atom (a).
Isotope - An atom with a different number of neutrons (c).

Step7: Calculate mass of 2 silver atoms

The atomic mass of silver is 107.87 amu. Mass of 2 silver atoms = 2×107.87 = 215.74 amu.
