Answer:
All elements have certain characteristics that are summarized on the periodic table. These characteristics include the element's symbol, atomic number, and atomic mass. You will learn how the number of protons in an atom relates to an element's atomic number, and explore how isotopes affect the atomic mass.
An element is a material that consists of a single type of atom. Each atom type contains the same number of protons. Chemical bonds link elements together to form more complex molecules called compounds. A compound consists of two or more types of elements held together by covalent or ionic bonds.
Hydrogen (H) - nonmetal.
Helium (He) - nonmetal.
Oxygen (O) - nonmetal.
Neon (Ne) - nonmetal.
Nitrogen (N) - nonmetal.
