Atomic Structure Crossword

specific shells or orbitals outside the nucleus that are defined by how much energy they can hold (also where electrons can be found)
A wave like space around the nucleus where electrons can be found.
A species of atoms having the same number of protons and neutrons in their atomic nuclei ex.) carbon, oxygen, sodium
the number of protons in the nucleus of an atom, which determines the chemical properties of an element and its place in the periodic table.
a stable subatomic particle occurring in all atomic nuclei, with a positive electric charge
the mass of an atom of a chemical element expressed in atomic mass units. It is approximately equivalent to the number of protons and neutrons in the atom (the mass number) or to the average number allowing for the relative abundances of different isotopes.
usually refers to the one- or two-letter abbreviation for a chemical element
an electron in an outer shell of an atom that can be lost to or shared with another atom to form a molecule
a stable subatomic particle with a charge of negative electricity
the positively charged center of an atom that contains most of its mass
the smallest unit of an element that has the chemical properties of that element
a subatomic particle of about the same mass as a proton but without an electric charge, present in all atomic nuclei
The way we organize chemical elements using their atomic number. It is organized into rows and columns.
Different forms of the same element that contain the same number of protons but a different number of neutrons.
