How many valence electrons in a ground state sulfur atom can have the quantum numbers ml = +1 and ms = + ?
a. 6
b. 1

B. 1

Explanation:

The quantum numbers are:

n -> principal, which represents the shell and varies from 1 to 7;

l -> azimuthal, which represents the subshell and varies from 0 to 3;

ml -> magnetic, which represents the orbital and varies from -l to +l passing by 0;

ms -> spin, which represents the spin of the electron, +1/2 or -1/2

Each orbital (ml) can have at least 2 electrons, each one with different ms numbers. So, only 1 electron is possible to have quantum numbers ml = +1 and ms = +1/2 in the valence shell.

answer

fusion: the energy source of stars. the energy released from the collapse of the gas into a protostar causes the center of the protostar to become extremely hot. when the core is hot enough, nuclear fusion commences. fusion is the process where two hydrogen atoms combine to form a helium atom, releasing energy.
