The are two electrons in the 3s orbital of magnesium (Mg.)
21
There are two electrons in the outer shell and there are three shells in total. The first shell holds two. The second eight. Then the last is two.
The max. number of electrons that can fill the 3s orbital is 2.
Sodium (Na) has 1 electron in the 3s orbital and chlorine (Cl) has 7 electrons in the 3p orbital. Sodium gives away the one electron to Cl, leaving it with 8 electrons (octet) in the 2p orbital (like Neon). The chlorine takes that one electron giving it 8 electrons (octet) in the 3p orbital. The sodium then has a +1 charge, and the chloride ion now has a -1 charge. This is an ionic bond.
There are 9 occupied orbitals in a phosphorus atom's ground state: one 1s orbital, one 2s orbital, three 2p orbitals, one 3s orbital, and three 3p orbitals.
Sodium is in the third group in the periodic table. It meens that sodium has three shell. First shell - 2 electrons, second shell - 8 electrons, third shell (outer energy level) - 1 electron.
The 2 electrons from 3s orbital.
The 2s orbital and 3s orbital both have the same spherical shape and can hold a maximum of two electrons of opposite spin. They only differ because the 3s orbital is further out from the nucleus than the 2s orbital, thus the 3s orbital has a higher energy value.
Magnesium has a total of 12 electrons. The electron configuration would be 1s2 2s2 2p6 3s2. Therefore, 2 electrons in it's outer shell.
There are two electrons in the outer shell and there are three shells in total. The first shell holds two. The second eight. Then the last is two.
True
One electron in 3s orbital of sodium
All of 11 electrons in sodium are in different electron orbitals: 2 electrons are in 1s orbital, 2 in 2s, 6 in 2p and 1 in the 3s orbital. (This last one is the so-called valence electron)
The most common magnesium ion is Mg2+. It loses 2 electrons. By losing 2 electrons, Mg then has no electrons in the 3s energy level, drastically reducing the energy of the atom.

Two per level (that is, 2 1s, 2 2s, 2 3s, etc.)
Yes, it exists. If you write the orbitals in order of increasing energy, then you get it. The order is:- 1s<2s<2p<3s<3p<4s<3d<4p<5s<4d<5p<6s<4f<5d<6p..................... Here, you get the 3s orbital at the 4th place.
The max. number of electrons that can fill the 3s orbital is 2.
