AP PSYCHOLOGY

Detailed explanation-1: -Each element is distinguished by the number of protons, neutrons, and electrons that it possess. For example, carbon’s atomic number is 6, and has an atomic mass of about 12, because it has 6 positively charged protons and 6 non-charged neutrons.

Detailed explanation-2: -All atoms have protons, electrons and neutrons, but what makes each element unique is the number of protons. For instance, a helium atom has 2 protons. If you and give it another proton you get a different element altogether: Lithium, a metallic element with 3 protons.

Detailed explanation-3: -allotropy, the existence of a chemical element in two or more forms, which may differ in the arrangement of atoms in crystalline solids or in the occurrence of molecules that contain different numbers of atoms.

Detailed explanation-4: -Answer: Factors such as the symbol of the element, atomic number and atomic mass determine the characteristics of an element. Answer: The atoms of all the elements are made up of electrons, protons and neutrons.
