If ba+2 will reacts with n-3, the formula of the compound formed is:
Ivanshal [37]

If Ba^{+2} will reacts with N^{-3}, the formula of the compound formed is Ba_3N_2.

<h3>What is an ionic compound?</h3>

Ionic compounds are neutral compounds made up of positively charged ions called cations and negatively charged ions called anions.

Barium is a metal element and Nitrogen is a non-metal element, so they form an ionic compound. To make the formula of an ionic compound, first, we need to see the valence of the atoms, that is, how many electrons it can donate or it has to gain to have 8 electrons in the valence layer (octet rule).

Barium is in family 2, so it has two electrons in its valence layer, so it must donate these two electrons; Nitrogen is in family 15, so it has 5 electrons ins its valence layer and must gain 3 electrons.

Writing the ions they must form:

Ba^{+2}N^{-3}

First came the cation (positive charge), then the anion (negative charge), and the charges must change between them, without the signal, and will inform how many atoms are necessary for which element:

Ba_3N_2

Hence, If Ba^{+2} will reacts with N^{-3}, the formula of the compound formed is Ba_3N_2.

Which pair of nuclei can undergo a fusion reaction?
AVprozaik [17]
The correct answer is B. Fusion only happens between small atoms. Thus, hydrogen-2 and hydrogen-3 can undergo fusion. Fusion reaction happens when two or more nuclei combine or collide to form an element with a higher atomic number. In this process, some of the matter of the fusing nuclei is converted to energy.
