Answer:
1. A element is a substance that is made entirely
from one type of atom.
2.A compound is a substance formed when two or more chemical elements are chemically bonded together. ... Each molecule of water contains two hydrogen atoms bonded to a single oxygen atom.
3.the number of protons in the nucleus of an atom, which is characteristic of a chemical element and determines its place in the periodic table.
4.the total number of protons and neutrons in a nucleus.
5.A subshell is a subdivision of electron shells separated by electron orbitals. Subshells are labelled s, p, d, and f in an electron configuration
6.the electron configuration is the distribution of electrons of an atom or molecule in atomic or molecular orbitals.
Answer:
element-an element cannot be broken down into simpler substances and it is the purest form of matter
compound - A compound is the substance composed of 2 or more different types of elements, chemically combined
in fixed proportions
Atomic number- the number of protons determines the atomic number
Mass number-mass number of an atom is equal to the number of neutrons in its nucleus
subshell - shell within the shell is called subshell
electronic configuration- it is the distribution of number of electrons in a atom
