Number that defines the number of protons in an element or atom
Starts with
B
A chemical equation in which the stoichiometric coefficients have been adjusted in such a way that the number of atoms of each element is the same in the reactants and in the products.
Starts with
C
Two words. Forces between atoms that are responsible for for making chemical compounds.
Starts with
D
Vector quantity related to motion. Its starting point is the initial position and its endpoint is the final position.
Starts with
E
Distribution of electrons in an atom, in atomic orbitals.
Starts with
F
Non-metallic element in group 17, and the 2nd period.
Starts with
G
Metalloid in group 14, named after a European country.
Starts with
H
Type of intermolecular force which is present between the atoms of hydrogen of one molecule and the fluorine, nitrogen or oxygen atoms of another molecule.
Starts with
I
Type of chemical bond between metals and non-metals.
Starts with
J
Fifth planet from the Sun, and largest planet of the Solar System. It is a gas giant.
Starts with
K
Noble gas with atomic number 36.
Starts with
L
A way of representing atoms or molecules by showing electrons as dots surrounding the element symbol. One bond is represented as two electrons.
Starts with
M
A group of atoms bonding together.
Starts with
N
Part of the atom in which the mass and positive charge of the atom is concentrated.
Starts with
O
Tendency of the atoms to prefer 8 electrons in the valence shell.
Starts with
P
Vector quantity related to motion which indicates the location of the body with respect to a reference frame.
Starts with
Q
Current atomic model, proposed by Shröedinger and other physicists, which treats the electrons as matter waves.
Starts with
R
Defined by a point in space, called origin, and a set of perpendicular axes that intersect at the origin.
Starts with
S
Energy level consisting of 1 or more subshells, and each subshell consisting of 1 or more orbitals.
Starts with
T
Covalent bond in which three pairs of electrons are shared between two atoms.
Starts with
U
Motion at a constant speed.
Starts with
V
Motion quantity that gives both the rate of change of its position with respect to a reference frame and the direction of this change.
Starts with
W
Chemical element which atomic symbol is W.
Contains
X
A test under controlled conditions that is made to examine the validity of a hypothesis.
