Answer:

21H deuterium (D), 31H is tritium (T), 11H is hydrogen

Explanation:

11H: it has the greatest abundance, it has only one proton (it does not have neutrons).

21H (D): it has a proton and a neutron in its nucleus.

31H (T): it has a proton and two neutrons in its nucleus.

Remember that isotopes have the same atomic number, but a different mass number (elements in the number of neutrons differed).

Answer:

See below.

Explanation:

They are Hydrogen 1 , Hydrogen 2 (also called deuterium) and Hydrogen 3 (tritium)

Hydrogen has no neutrons in the nucleus while deuterium has 1 and tritium has 2.

Deuterium has been used in the nuclear industry ( as heavy water , deuterium oxide) and as a compound lithium deuteride in the H bomb. Tritium is also used as a fuel in nuclear fusion reactions, and as a radioactive tracer.

What is the correct formula for combining Mg2+ and Br1+

True [87]

Answer: The correct formula is $MgBr_2$

Explanation:

For formation of a neutral ionic compound, the charges on cation and anion must be balanced. The cation is formed by loss of electrons by metals and anions are formed by gain of electrons by non metals.

Here magnesium is having an oxidation state of +2 called as $Mg^{2+}$ cation and bromine $Br^{-}$ is an anion with oxidation state of -1. Thus they combine and their oxidation states are exchanged and written in simplest whole number ratios to give neutral $MgBr_2$ .
