Atomic Structure
Name the 3 subatomic particles in an atom, with their charges, and their locations.
Protons (+) and Neutrons (no charge) in the atom's nucleus. Electrons (-) outside the nucleus
An isotope is a combination of identical atoms that differ by their number of

What is an anion?
Number of neutrons in Sulfur-33
What is 17?
Element in period 5 Group 14
Tin (Sn)
As one moves from down ( ↓ ) a group on the periodic table, the electronegativity of the elements encountered tends to
decrease

Longhand Electron configuration for Magnesium (Mg)
What is 1s2 2s2 2p6 3s2
If atoms contain charged particles, why do they not have a charge?
Protons and Electrons are equal which cancels out the charge.
