How is it possible for an atom to have no charge even though it is made up of protons, neutrons, and
electrons?
An atom has no charge because there are an equal number of positively-charged protons and negatively-charged
electrons.
The mass of an atom may be determined by adding the masses of the protons and neutrons in the nucleus.
Why is it unnecessary to include the electrons when determining the mass of an atom?
The electrons are not necessary to include when determining the mass of an atom because they have virtually no mass
at all.
Why is the atomic mass of an element not given as a whole number on the Periodic Table even though each
individual atom of the element has a whole number of protons and neutrons?
The atomic mass on the periodic table is an average weighted mass of all known isotopes of that element.
With as much detail as possible, please explain why hydrogen (H) is where it is on the periodic table.
Hydrogen is not an alkali metal (it’s not a metal at all), but it is in the same column as the alkali metals because it shares
the characteristic of having one valence electron. It is in the first period because it has only one electron shell. It is
atomic number 1 because it has just one proton.
With as much detail as possible, please explain why helium (He) is where it is on the periodic table.
Helium is considered a noble gas and is in the 18th group of the periodic table because it shares the noble gas
characteristic of having a full valence electron shell and being relatively unreactive with other elements. Helium does not
have 8 valence electrons like the other noble gases- it has only 2, but the first electron shell is ‘full’ with only 2 electrons.
Helium is in the first period because it has only one electron shell. It is atomic number 2 because it has two protons.
