Periodic Table of Elements
Periods are the horizontal division of the periodic table and they tell you the charge of these elements in each specific period.
Groups are the vertical division of the periodic table and they tell you the valence electrons of the elements and there are a few exceptions.
Valence Electrons: it depends on what group the element is found in
-Metals: You find Metals in the middle of the periodic table
-Nonmetals they are found in group 18 and these elements: f, cl, br, i, o, s, se, n, p, c and h.
-Metalloids Beside the stair steps in the periodic table
-Atomic Number The atomic number tells us how many protons are in the element and they are arranged in numerical order.
-Atomic Mass The atomic mass is found at the bottom of each element and it tells us how much the nucleus weighs and helps tell us how many neutrons are in the nucleus.
*Explain how you know if elements are highly reactive or not. The closer to the edge it is the more reactive because it has more/less valence electrons to bond with and its easier to bond.
*List the properties of metals, nonmetals, and metalloids using physical properties such as luster conductivity, and malleability. Metals are very conductive and malleable , non metals are not conductive at all and metalloids share both characteristics of metals and non metals.
