Explanation:
a) What are elements?
=> In chemistry, an element is a pure substance which cannot be broken down by chemical means, consisting of atoms which have identical numbers of protons in their atomic nuclei. The number of protons in the nucleus is the defining property of an element, and is referred to as the atomic number (represented by the symbol Z). Chemical elements constitute all of the baryonic matter of the universe.
b) What are the three main types of elements?
=> There is metals, nonmetals and metaloids. Specifically there is 8 different categories Alkali metals, Alkali Earth metal, Transition metals, Other metals, Other nonmetal's Halogens, Noble Gases and Rare Earth metals.
c) Write property of each type of element?
=> The elements in the periodic table are arranged in order of increasing atomic number. All of these elements display several other trends and we can use the periodic law and table formation to predict their chemical, physical, and atomic properties. Understanding these trends is done by analyzing the elements electron configuration; all elements prefer an octet formation and will gain or lose electrons to form that stable configuration.
