atom and mucleus
electromagnetic froce
. The attraction or repulsion between charged particles. Electrons
electron
.The negative charge particles that orbit the nucleus of every atom. The attraction or repulsion between charged particles. Electrons
mucleus
.the small parts that comprise an atom:protons,neutrons, electrons.(460-370 BCE) A Greek philosopher who theorized that all matter could be reduced to particles that could not be divided, witch is an atom
atomic number
the number of protons in an atom
nuclear
the strongest force known
ionic bond
the type of chemical interaction in witch atoms lose or gain
covalent bond
the type of chemical interaction in witch atoms sshare electrons
elements
unique pure substances that are comprise of atoms that have the same number of protons.they combined 100 elements.
democritus
(460-370 BCE) A Greek philosopher who theorized that all matter could be reduced to particles that could not be divided, witch is an atomA subatomic particle located in the nucleus of an atom that carries a positive charge.
neutron
A subatomic particle with a neutral charge located in the nucleus of an atom .The negative charge particles that orbit the nucleus of every atom.
protons
A subatomic particle located in the nucleus of an atom that carries a positive charge. A subatomic particle with a neutral charge located in the nucleus of an atom .
subatomic particle
The center of every atom, containing positively charged protons and neutrally charged neutrons. The number of protons in a given nucleus distinguishes one element of anther.the small parts that comprise an atom:protons,neutrons, electrons.
periodic tables of elements
The scientific chart that contains all elements
atoms
The small particles make up matter,consisting of a nucleus containing protons and neutrons surrounded by orbiting electrons.
ion
an atom or a group that carries an electric charge
chemical bond
interaction among atoms that occurs when electrons are shared
compounds
substance formed by the joining of elements through chemical bonding
atomic mass
the average mass by adding the number of protons and neutrons
