Questions and Correct Answers, 100%
Correct. Updated Fall 2024/2025.
Matter

Anything that takes up space and has mass.

Element

Substance that cannot be broken down to other substances through chemical reactions. Each has a
symbol. 92 occurring in nature.




Compound

Substance consisting of two or more different elements combined in a fixed ratio.
*Characteristics different than those of its elements




CHON

4 elements essential to life

Trace Elements

Required by an organism only in minute quantities.

Atom

Smallest unit of matter that retains the properties of an element. Composed of subatomic particles.
Mostly empty space.

Subatomic particles

,Neutrons, protons, electrons. Make up atoms.

Proton

One unit of positive charge. Approximately one dalton. Located in nucleus.




Electron

One unit of negative charge. Located outside of nucleus.




Atomic Nucleus

Dense core packed with protons and neutrons.




Neutrons

Electrically neutral. Approximately one dalton.




Atomic Number

The number of protons (which is unique to that element) and written as a subscript to left of element
symbol. Also tells us number of electrons since P=E if atom is neutral

,Mass Number

Sum of the protons and the neutrons. An approximation of the atomic mass.




Isotopes

Same number of protons, but different number of neutrons and therefore different mass. Same element.




Radioactive Isotope

One in which the nucleus decays spontaneously, giving off particles and energy. Can decay to a different
element. Have useful applications.




Energy

Capacity to cause change

Potential Energy

Energy matter possesses because of its location or structure. Electrons have this based on distance from
nucleus.

, Electron Shells

Where electrons are found, each with characteristic average distance and energy level. Electrons can
change these by absorbing or losing energy.




Valence Electrons

Electrons in the outermost shell.




Chemical Bonds

The attraction that holds atoms together during an interaction.

Covalent Bond

Sharing of a pair of valence electrons by two atoms.




Molecule

Two or more atoms held together by covalent bonds.

Single Bond

One pair of shared electrons.

Structural Formula
