Dmitri Mendeleev and Henry Moseley developed their periodic tables about forty years apart. During that time, many discoveries i

n chemistry were made. Which fact was most likely discovered between the time of Mendeleev’s table and the time of Moseley’s table that helped Moseley develop his version? Atomic mass is the average mass of different samples of the same element. Different elements can have similar chemical properties even if their atomic masses are different. The number of protons in an atom is different than the atom’s total mass. Protons strongly affect an element’s atomic mass, while the electrons in atoms do not.

How many electrons in an atom can share the quantum numbers n = 2, l = 1?<br> 1<br> 3<br> 6<br> 10
Igoryamba
Principal quantum number is n = 2, principal quantum number gives the energy shells electrons reside in,
angular momentum quantum number , these are the number of subshells and gives how many subshells are there in energy shells, values for l range from 0 to n-1
magnetic quantum number -m- gives the specific orbital in the subshells and their orientation.
spin quantum number gives the spin of the electrons.

in this case, n = 2
the types of subshells in n=2 are 0 and 1
0 - s subshell 
1 - p subshell
the  specific number of orbitals are given by -l to +l
when l = 1
then -1, 0 and +1
therefore there are 3 orbitals in p subshell and orbitals are in 3 orientations
each orbital can hold a maximum of 2 electrons, 
since there are 3 orbitals each holding 6, there are 6 electrons to which these quantum numbers are the same
answer is 6
