Protons, Neutrons, Electrons
A Proton has what charge?
negative charge
Where is the Atomic Mass on the element (periodic table)
Top left corner
Where do you find the electron configuration?
What is an ion
any atom or group of atoms that bears one or more positive or negative electrical charges.
When there two or more species of a chemical element with the same atomic number and position on the periodic table it is...
What a isotope
What is the location of a neutron
The Nucleus
Two atoms will always have the same atomic number if they have the same...?
number of protons
What is the valance electron?
the last electron in the electron configuration.
When writing Chlorine Atom do you add 1 take away one or do nothing to the valence electron when writing it visually?
Protons = ?
atomic #
Does the Proton Neutron or Electron have an insignificant mass?
What is the electron has an insignificant mass.
What is the Atomic mass of lithium (round to nearest tenth!)
6.9
Is 1-6-13-3 ok for the excited state of manganese
No! A correct version would be 1-7-13-4
how many valence electrons are there in a Neon ion?
8 - since there the number on the top right is 0 you don't add or subtract any from the valence electron
What page is your Periodic table on?
9
The atomic number is the same as...
number of protons and electrons (the answer could be protons, electrons or both.)
Steps for natural abundance
1) convert all percent abundances to decimal #
2) multiply each decimal abundance by the isotopes
3) add the results
4) Check your periodic table to see if your close
If you see -4 on the upper right corner of the element do you add or subtract to valence electron for an ion? And how much?
You add 4

When you see the electron configuration of Francium it is -18-32-18-8-1. What are the first two electron places in this electron configuration? How did you know?
2-8-
Look at the bottom of the reference table page 9
