Bronchi that is the answer
Answer:
Mg²⁺
Explanation:
The electron configuration of Mg is [Ne]3s².
It is easier for Mg to get a complete octet by losing two electrons and exposing the neon core than it is to add eight electrons and get an Ar octet.
The most stable monatomic Mg ion is Mg²⁺.
No, they do not. It is not true.
You can define an element as a substance with only one type of atom in
(e.g. only sulphur atoms). If a substance has more than one type of atom
in, then it is either a compound or a mixture, depending on whether the
elements have bonded. Examples of elements are:
Oxygen
Sulphur
Carbon
Hydrogen
Protactinium
Compound-
A substance made up of atoms of two or more different elements joined by chemical bounds.
Molecule- a pure substance that cannot be broken down
Salt- A Ionic Compound Formed From The Reaction Of An Acid And Base .
I believe the answer is "hard water"
