Chemistry ahhhhhhhhhhhhh

lalalalalala

What determines the identity of the atom

Proton # = Atomic #

Identity of an atom

element

What determines the isotope of the element

neutron

Isotope

Variants of an element that have the same number of protons but different numbers of neutrons.

Ion

a charged particle formed when an atom gains or loses electrons.

What determines the charge of the atom

the number of electrons (charge = pprotons - electronsro

number at the top of a element or to the bottom left

Atomic #

number below an element or to the top left

Mass #

number to the top left

the charge

Charge, mass, and location of proton

1amu, neucleus, +/ cation

Charge, mass, and location of neutron

1amu, nucleus, neutral

Charge, mass, and location of electrons

negative, 0.000548 amu, electron cloud

Average atomic mass formula

(%1 x mass1) + (%2 x mass2) / 100

What differentiates isotopes of the same element

Isotopes of the same element differ in the number of neutrons in their nuclei, leading to variations in their atomic masses.

Alpha decay

Beta decay

Gamma ray decay
