Elements in Group 1 have 1 more electron than the noble gas in the row above it.
Elements in Group 2 have 2 more electrons than the noble gas in the row above it.
Elements in Group 15 have 3 less electrons than the noble gas in the same row as it.
Elements in Group 16 have 2 less electrons than the noble gas in the same row as it.
Elements in Group 17 have 1 less electrons than the noble gas in the same row as it.

This is a method of relating how two or more elements or texts are SIMILAR.?
compare
Can be used to easily compare properties of different elements?
The Periodic table
If the volume of a proton is similar to the volume of an electron how will the densities of these two particles compare?
Proton mass = approx. 1,850 x electron mass.If volumes are similar, then proton density = approx. 1,850 x electron density.
What is the Compare and contrast the properties of the halogens with alkali metal?
elements in the halogen family react easily with other elements whose atoms can give up electrons.alkali metals lose one electron they are left with 0 valence electrons and they become more chemically stable
How do you compare the reactivity of a set of elements?
Electronegativity is a measure of the reactivity; see the link below.
How do the valence electron configurations of the alkali metals compare with others?
The valance electron configuration is the same in each at ns1 where n = the period number.
Compare the stability of a lithium atom with that of its ion Li plus?
Li+ means that the atom lost an electron. And this means it has now has a complete outershell, thus being more stable than the Lithium atom with 1 valence electron

Planets.
How does the mass of a electron compare to the mass of a proton and neutron?
Mass ratio proton (neutron)/electron: 1 836
How does the mass of electron compare to the mass of the proton?
The proton mass is about 2,000 times greater than the electron mass.
How does the mass of an electron compare to the mass of proton?

How does the mass of a proton compare to the mass of a neutron and an electron?
Mass ratio proton (neutron)/electron: 1 836
Why is the periodic table important to chemists?
The way that elements are arranged on the Periodic Table tells you some properties of the elements and how they relate to other elements. Elements in the same group (column) will exhibit some similar chemical properties, because their outer electron configurations are the same, for example.
