<span>Helium = 1
Carbon = 8
Nitrogen = 8
Strontium = 52
Tellurium = 71
If you look on a periodic table, on each element there is a number on
the top left. This represents the number of protons in an atom. Protons
have a mass of 1 (in relative to Carbon-13)
If we take nitrogen-15 for example; The number 15 tells you that the
isotope has a mass of 15. Now if you look on the periodic table,
Nitrogen has a proton number of 7. Only protons and neutrons have a
mass, electrons are considered to be negligable. Therefore the number of
neutrons Nitrogen-15 contains is 15 - 7 = 8 </span>
Answer:
Blue: Because violet really has the most and blue is based on violet!
Explanation:
Hope this helps! Plz mark as brainliest!
10.92N
Force = mass x acceleration
4.2kg x 1.6m/s^2 = 10.92N
Non metal atoms got this from google btw
It's A. volume
Pressure =
with const depends on the chosen unit of volume
I think so...
