Moles of iron = 7.30
<h3>Further explanation</h3>
Given
mass of iron = 408.67 g
Required
moles of atoms
Solution
The mole is the number of particles contained in a substance
1 mol = 6.02.10²³
Moles can also be determined from the amount of substance mass and its molar mass
mol iron-Fe (Ar = 56 g/mol)
mol = mass : MW
mol = 408.67 g : 56
mol = 7.30
C, the one with the most neutrons
Answer:
Rubidium
Explanation:
Rubidium has atomic number 37 and belong to group one alkali metals and has one valence electron at the outermost shell whiz is 5s1
the mass of the shells will remain the same because you can not change mass even if you were to leave this planet and go to the moon your weight would change but your mass remains the same
There are three subatomic particle that are present in an atom. These are electrons, protons, and neutrons. Among these three, I believe the <span>subatomic particle that plays the greatest part in determining the properties of and element would be the electron. It is what determines how the element would react in different conditions.</span>
