What is the reactive pattern of group 1 elements?
The Group 1 metals get more reactive as we go down the group.

Why were group 0 elements not included in the first periodic table?
The noble gasses had not yet been discovered, and there was no reason at that time to suspect their existence.

Who was Mendeleev and what is he famous for?
Dmitri Mendeleev was a Russian chemist in the 1800s who is most famous for his work on developing the periodic table of elements. He discovered that there was a regularity to the known elements by arranging them in order of their atomic weights.

List some properties of Metals and what they mean.
Metals, shiny solids, are room temperature (except mercury, which is a shiny liquid element), with characteristic high melting points and densities.Many of the properties of metals, including a large atomic radius, low ionization energy, and low elec

What group is Oxygen in and how do you know without looking at a periodic table? (Hint, it's to do with the electrons in the valence shell).
Determine the group number and period number of the element. The vertical columns of the periodic table, counting left to right, 1 through 18, are called groups. In the periodic table, elements with similar chemical properties are in the same group.
