![N^{3-},Mg^{2+}](https://tex.z-dn.net/?f=N%5E%7B3-%7D%2CMg%5E%7B2%2B%7D)
![S^{2-},Ti^{4+},K^{+}](https://tex.z-dn.net/?f=S%5E%7B2-%7D%2CTi%5E%7B4%2B%7D%2CK%5E%7B%2B%7D)
Explanation :
Isoelectronic : It is defined as the compound or molecule having the same number of electrons and the same number of electronic structure.
- The element is helium. The number of electrons are 2.
- The element is beryllium. The number of electrons are 4. The number of electrons in
= 4 - 2 = 2 - The element is lithium. The number of electrons are 3. The number of electrons in
= 3 - 1 = 2 - The element is nitrogen. The number of electrons are 7. The number of electrons in
= 7 + 3 = 10 - The element is neon. The number of electrons are 10.
- The element is sulfur. The number of electrons are 16. The number of electrons in
= 16 + 2 = 18 - The element is magnesium. The number of electrons are 12. The number of electrons in
= 12 - 2 = 10 - The element is titanium. The number of electrons are 22. The number of electrons in
= 22 - 4 = 18 - The element is potassium. The number of electrons are 19. The number of electrons in
= 19 - 1 = 18
The isoelectronic groups are:
![He,Be^{2+},Li^{+}](https://tex.z-dn.net/?f=He%2CBe%5E%7B2%2B%7D%2CLi%5E%7B%2B%7D)

Explanation:
Answer:
Molar mass is the mass of a given substance divided by the amount of that substance, measured in g/mol. For example, the atomic mass of titanium is 47.88 amu or 47.88 g/mol. In 47.88 grams of titanium, there is one mole, or 6.022 x 1023 titanium atoms.
