atom

the smallest particle that still contains the properties of that element

element

any of the more than 100 known substances (of which 92 occur naturally) that cannot be separated into simpler substances and that singly or in combination constitute all matter

neutrons and protons

the two sub atomic particles that make up the nucleus

found orbiting the nucleus, negative

where are electrons found, what kind of charge?

atomic number

tells the number of protons in that atom

= number of protons and electrons

neutral atom has an..

mass number

the sum of the protons and neutrons

proton

a subatomic particle with a positive charge

nuclide

atom of an element that has a fixed number of protons and neutrons

isotope

same element hat has same protons but different neutrons

Ion

when the atom has a positive or negative charge

Anion

negative charge type of ion

Cation

positive charge type of ion

valance electrons

outermost shell that controls bonding in the electron

valance

type of electrons the lewis dot structure shows

periodic table

collection of all the known elements arranged in order by atomic #

metals and nonmetals

what the stair step separates

mass spectrometer

an instrument that separates ionized atoms or molecules based upon their ratio of charge to mass.

Quantum theory

theory that in the universe energy is transferred through very small particles at the atomic and subatomic level

octet rule

rule that you need 8 in the valance shell to be stable
