Atomic weight (Atomic Mass) - ✔️✔️is the #that indicates how much matter that atom
contains compared w/ another atom. (# of P+) + (# of N) = atomic mass units
Kinetic energy - ✔️✔️involves adding heat energy to make its molecules move faster,
to ^ the energy of motion. / energy in motion
Potential energy - ✔️✔️stored energy / energy @ rest
Quantum - ✔️✔️amount of energy needed to move an electron from 1 energy lvl to the
next.
Orbital - ✔️✔️electrons move through characteristic regions
What is the charge of a proton? - ✔️✔️+
What is the charge of a neutron? - ✔️✔️0
What is the charge of an electron? - ✔️✔️-
Atomic number - ✔️✔️the # of protons
Element - ✔️✔️are substances that cannot be broken down into simpler substances by
ordinary chemical reactions.
Isotope - ✔️✔️form of an atom w/ a specific # of neutrons.
According to the Bohr model of the atom, how many orbitals are there in the first energy
level?
How many in the second?
How many in the third? How many electrons can each orbital contain? - ✔️✔️1st- 2
2nd- 8
3rd- 8
Molecule - ✔️✔️two or more atoms may become joined very strongly to form stable
particle.
