The periodic table

the periodic law states that elements that have similar properties appear

most elements are

elements within the same group in the PT have similar properties becuase they have the same

silicon, a semiconductor, is often found in 

most halogens form compounds by

mendeleev studied the properties of elements and looked for

atoms that gain or lose electrons are called

as you move from left to right across the periodic table, elements

each column of the periodic table is

magnesium (Mg) is located to the right of sodium (Na) because Mg has

atoms of elements that are in the same group have the same number of

which statement about the alkali metals is correct?

a lithium ion is much less reactive than a lithium atom because it

in mendeleev's periodic table, elements in each column had similar

the three main groups of elements are metals, nonmetals, and 

elements in an element family have similar

the order of elements in the modern periodic table is based on an element's
