Chemistry Review Sheet - Atomic Structure and Bonds

Vocabulary flashcards generated from the atomic structure and chemical bonding review sheet.

HON C

A mnemonic rule indicating the number of covalent bonds formed by Hydrogen (1), Oxygen (2), Nitrogen (3), and Carbon (4).

Formula for Neutrons

$$\text{Neutrons} = \text{Atomic mass} - \text{protons}$$

Atomic Number

Tells how many protons and electrons there are in an atom.

Atomic Mass

Tells how much protons and electrons are when they combine.

Proton

A subatomic particle located in the nucleus with a positive ($+\text{charge}$).

Neutron

A subatomic particle located in the nucleus.

Electron

A subatomic particle located outside of the nucleus/energy level with a negative ($-\text{charge}$).

Lithium (Li)

An element with 3 protons, 3 electrons, and 4 neutrons.

Aluminum (Al)

An element with 13 protons, 13 electrons, and 14 neutrons.

Phosphorus (P)

An element with 15 protons, 15 electrons, and 16 neutrons.

Iron (Fe)

An element with 26 protons, 26 electrons, and 30 neutrons.

Iodine

An element with 53 protons, 53 electrons, and 74 neutrons.

Silicon

An element with 14 electrons and 14 protons.

Argon

An element with 18 electrons and 18 protons.

Ionic vs. Covalent Bonds

According to the review sheet notes, an ionic bond shares electrons while covalent bonds transfer electrons.
