Hey there!:
* For 2p subshell :
n = 2, l =1, ml = -1, 0, +1
* for 5d subshell,
n = 5, l = 2, ml = -2, -1, 0, +1, +2
Hope that helps!
The answer is (4) at the cathode, where reduction occurs. The Na+ gains one electron and become Na(l). So the reaction occurs at cathode and is reduction reaction.
Answer:
.
Explanation:
Lithium is in the first column of the periodic table, so it will have 1 valence electron.
Bromine is in the seventh column of the periodic table, so it will have seven valence electrons.
They must combine in a way to reach 8.
When combining elements to form compounds, the "crisscross method" is used. Above Li would be a charge of +1, and above Br would be a charge of -1.
Cross the 1 from the top of Li to the bottom of Br, and so there is 1 Br.
Cross the 1 from the top of Br to the bottom of Li, and so there is 1 Li.
It is not written BrLi because chemists decided to order them the other way. Technically speaking, it isn't wrong, but the positive charge is normally put on the left and the negative charge is normally put on the right.
Answer:
Argon has 8 valence electrons and no extras, it does not require a bond in order to fill its shells, its satisfied by itself.
Chlorine is missing 1 Electron, if it connects with another Chlorine it will be satisfying both of their needs with a Covalent bond.
Explanation:
Answer:
Protons have a much larger volume than neutrons.
Explanation:
Protons have a slightly smaller mass than neutrons.
Protons have a positive charge.
Protons and neutrons make up the nucleus.
