Answer:
Answers are bellow.
Explanation:
The element with electron configuration 1s22s22p63s1 belong I A group in the periodic table and it is sodium because it loses one electron.
We have periodic table in attachments.
Sodium is a chemical element with the symbol Na and atomic number 11. It is a soft, silvery-white, highly reactive metal. Sodium is an alkali metal, being in group 1 of the periodic table, because it has a single electron in its outer shell, which it readily donates, creating a positively charged ion—the Na+ cation. Its only stable isotope is 23Na.
The free metal does not occur in nature, and must be prepared from compounds.
It is soft metal, reactive and with a low melting point.
Answer:
yes
Explanation:
sodium is salt and you can get it in the store or anywere.

Answer:
No. If you were to set up what the friend said it would look like this:
19.7g × ==> ×
The above does not look right because the grams do not cancel out. If it's not cancelled, it would be included in your final answer, but you're looking for moles not grams.
When setting up a stoichiometry equation, you have to put the same unit of measurement (ex- grams, cm, mm, etc.) on the numerator of one side and the denominator of the other side.
This would cancel out the unit.
For example: If you wanted to find out how much of 320 cm are in a meter.
*there are 100 cm in 1 meter*
(1. always start with the given number!)
(2. set up the next fraction where you can cancel out cm)
× = 3.2 m
Going back, your friend would have to switch the units from grams/moles to moles/grams. It would cancel out grams, which would leave moles. Therefore, moles will be included in your final answer.
× = _?_ moles
