<h2>Halogens.</h2>
Explanation:
All of the halogens form salts with alkali metals with the formula MX.
Halogens are the members of group 17 in the periodic table. They have seven electron in their valence shell and tend to form negative ion with minus one charge. They get there name because of their property to form salts. Halogens are very reactive and form salts with the metals.
Answer:
The meaning of star system is "A small number of stars." I think it's either A) a group of hundreds of stars, or B) a group of two or more stars.

hope we can be friends
can i please get brainliest
Explanation:
The orbital diagram of an electron with eight electron is attached. Since the 2p orbitals are filled using the maximum space available instead of pairing the electrons, this is in accord with Hund's rule.
When filling orbitals, you should put one electron in each box. After all of the boxes in the orbital have one electron in each, you can then put the second electron into each of the boxes.
Answer:
1.25 g/L.
0.0214 mol/L.
Explanation:
Concentration in g/L = 5/4
= 1.25 g/L (answer).
As for mol / L we need to know the molar mass of salt.
It is 22.99 + 35.45 = 58.44.
So in mol/L it is 1.25 / 58.44
= 0.0214 mol/L.
Many aging processes are oxidation processes in which oxygen is the electron acceptor either directly
