What is the total number of protons neutrons and electrons in sodium and chlorine after they interact?
First split salt into its components Na-Sodium and Cl-Chlorine; take a look at the periodic table and you'll see the atomic number (at the top of the box of an element) that number is how many protons are in the element, so you add the atomic number for sodium-11 to the atomic number for chlorine-17 and you get 28 protons all together in salt, that means that you must also have 28 electrons (the number of electrons must be the same as the number of protons). Now to solve for neutrons take a look at the number at the bottom of the periodic table (known as the mass number or amu or atomic mass units-not shown on all periodic tables so you may have to look it up) for Sodium it's 22.98977 and for Chlorine it's 35.4527 now what that means is the weighted average mass of all the isotopes of the element, what you can do is round that number to 23 and 35, then add those two numbers together making 58 ( the total number of protons + neutrons) then subtract 28 from 58 to give you 30 neutrons (though the number of neutrons varies depending on the isotope of the elements 30 neutrons is the most common isotope of salt). That leaves you with a grand total of 28 protons, 28 electrons, and 30 neutrons.

What does argon look like with protons and neutrons surrounding it?
Argon has 18 protons and 22 neutrons in the nucleus. It has 18 electrons surrounding the nucleus with 2, 8 and 8 electrons in the three shells.
What does the Bohr model of argon look like?
argon is odorless, colorless, pratically invisible....
How would you use the Periodic Table to find out how many electrons are in a chlorine atom?
Look at the atomic number. That is the number of protons. Assuming a non-ionic form of Chlorine, that is also the number of electrons.

How many electrons does chlorine have in the highest occupied energy level?
There are 3 energy levels in chlorine. Look at the shell notation: 2-8-7. So there are 8 electrons in the highest energy level.
What does the argon look like in its normal state?
Argon is a noble gas. At S.T.P. it is a colourless odourless gas.
What is number of electrons in chlorine?
To find this out, we'll look at a period table to find chlorine's atomic number. This tells us its number of protons, which, as it turns out, is 17. We know that protons and electrons carry equal but opposite charges, so to balance the net charge of chlorine back to 0, it must have 17 electrons.
What does argon look like in its natural state?
It is a colourless gas.
How many electrons does sodium need to achieve a noble gas configuration?
Sodium has 11 electrons, and one valence electron To achieve noble gas configurations, it would have to gain 7 electrons, for a total of 18 like Argon has. But this gain is impossible. So Sodium loses one electron to look like Neon which has 10.

How can the periodic table help you determine the number of valence?
Just look at how many columns it is from the left side, sodium has 1 valence electron, magnesium has 2... chlorine has 7 and argon has 8
