1s electrons = 2
2s electrons = 2
3s electrons = 2
4s electrons = 2
so a total of 8
Arsenic has 5 [valence electrons] in them.
Five, Arsenic is in group 15
The arsenic ion with a -3 charge has gained 3 electrons, giving it a total of 3 more electrons than the neutral arsenic atom. Arsenic typically has 33 electrons in its neutral state, so the arsenic ion with a -3 charge would have 36 electrons.
The AS3- ion has 36 electrons. This is because arsenic (As) has 33 electrons, and the addition of 3 extra electrons (the negative charge) brings the total to 36 electrons in the ion.
In an atom of arsenic (As), there are 33 protons, 33 electrons, and typically 42 neutrons.
That atom is Arsenic. It would have 33 electrons.
Arsenic has a mass number of 33 with an electron configuration of 1s2 2s2 2p6 3s2 3p6 4s2 3d10 4p3. This means that there are 3 valence electrons.
Arsenic has 33 protons/electrons and 42 neutrons.
Element thirty three is Arsenic and can be fatal to humans.
