In a(n) ________, the number of electrons is equal to the number of protons.
9
New cards
models
Scaled- up ________ are often used to visualize things that are too small to see.
10
New cards
Isotopes
________: Atoms of the same element that have different numbers of neutrons.
11
New cards
Periodic Table
________: the elements are arranged by increasing atomic number and by changes in physical and chemical properties.
12
New cards
Atomic Mass
Average ________: the weighted- average mass of the mixture of its isotopes.
13
New cards
electrons mass
Because a(n) ________ is small and the electron is moving so quickly around the nucleus, it is impossible to describe its exact location in an atom.
