Chemistry

Almost all of the mass of an atom (more than 99%) is in its nucleus, so "atomic mass" is pretty much a measure of the size of the nucleus of an atom. The nucleus of an atom is made up of protons and neutrons. Protons and neutrons are almost exactly the same size.

Construct <br> an isotope has 17 protons 20 neutrons and 18 electrons
ASHA 777 [7]
Add proton + neutrons = Mass 37

Proton is same as your atomic mass= 17

If you go on the periodic table look up 17 and it will give u the letter.

Chromium has a smaller atomic radius than iron. *<br> O<br> True<br> False
Sunny_sXe [5.5K]

Answer:

False

Explanation:

Atomic radius is defined as the distance between the nuclei of 2 identical atoms that are bonded together

Now, from periodic tables, chromium has a calculated atomic radius of 1.66 Å while iron has a calculated atomic radius of 1.56 Å

Thus, chromium has a bigger atomic radius than iron.

So the statement is false.
