Answer :
Answer:
The element nitrogen forms an anion with the charge -3. The symbol for this ion is N³⁻, and the name is nitride. The number of electrons in this ion is 10.
Explanation:
The element nitrogen is in the Group 15 in the Periodic Table, so it tends to gain 3 electrons (3 negative charges) to fill its valance shell with 8 electrons.
The element nitrogen forms an anion with the charge -3. The symbol for this ion is N³⁻, and the name is nitride. The number of electrons in this ion is 10 (the original 7 plus the 3 gained). It is isoelectronic with the gas Neon, which accounts for its stability.
Final answer:
Nitrogen forms an anion with a charge of -3 when it gains 3 electrons. The symbol for this ion is N^-3 and it's called a nitride ion. The number of electrons in this ion is 10.
Explanation:
The element nitrogen can form an anion or a cation depending on whether it gains or loses electrons. When nitrogen gains 3 electrons, it forms an anion with a charge of -3. The symbol for this ion is N-3, and the name is nitride ion. The atomic number of nitrogen is 7, which means a neutral nitrogen atom has 7 electrons. So, when nitrogen gains 3 electrons to form a nitride ion, the total number of electrons is 10.
