The name and atomic symbols of the four most abundant elements, which make up the bulk of all living matter and the ones, which occur in proteins and
Introduction:
The whole universe is made of matter and the matter is composed of the elements. The elements are made up of smaller particles known as atoms. The protons, neutrons, and electrons make up the subatomic particles of an atom. The number of protons present within the nucleus determines the atom’s atomic number. Each element is denoted by its symbol, which is universal and unique.

According to chemist John Dalton, if one mole of nitrogen is combined with three moles of hydrogen to form one mole of ammonia (knowing that nitrogen, with an atomic number of 7, has an atomic mass of 14, and hydrogen, with an atomic number of 1, has an atomic mass of 1), then this compound will have an atomic weight (or molecular mass) of:
14 grams per mole (14 daltons)
17 grams per mole (17 daltons)
20 grams per mole (20 daltons)
22 grams per mole (22 daltons)
43 grams per mole (43 daltons)
The “octet rule” in chemistry helps predict the types of bonds thatatoms will form. In general, an atom will be most stable if it fills itsouter shell of 8 electrons. Atoms with fewer than 4 valence electronstend to donate electrons and those with more than 4 valence electronstend to accept additional electrons; those with exactly 4 can do both.Using this rule, determine what category each of the followingelements falls into: N, S, C, P, O, H, Ca, Fe, and Mg. (You will needto work out the valence of the atoms.)
The naturally-occurring amino acid L-serine (NH2-CH(COOH)-CH2-OH, dry form) shares all of the
following features with the naturally-occurring amino acid D-serine, except:
the same three-dimensional arrangement of covalent bonds
the same stoichiometry
the same number of covalent bonds
the exact same atoms
the same number of atoms
