What’s the electron configuration of an N-3 ion

Chemistry
1 answer:
Alla [95]3 years ago
8 0

Answer:

1s2 2s2 2p6

Explanation:

The nitride ion(N^3-) is formed when nitrogen gains three electrons. Nitrogen possesses seven electrons in its orbitals and ordinarily has the electronic configuration; 1s2 2s2 2p3. However,being in group 15, nitrogen can accept three electrons to form the nitride ion and complete its octet of electrons. When this happens, three electrons are added to the nitrogen atom and the electronic configuration is now the same as that of Neon, its closest noble gas which is 1s2 2s2 2p6. Hence the answer given above.

Elements can accept or donate electrons in order to complete their octet structure in accordance to the octet rule which states that atoms and ions must possess eight electrons in their outermost shell in order to attain chemical stability. The reason for ion formation and chemical reaction is in order for species to attain the octet structure.

Inner planets usually have...
BigorU [14]

Answer:

Shorter revolution times, Made of rock, No rings

Explanation:

want more facts? Here u go!

The four planets closest to the Sun—Mercury, Venus, Earth, and Mars—are the inner planets or terrestrial planets (Figure below). They are similar to Earth. All are solid, dense, and rocky. None of the inner planets has rings. Compared to the outer planets, the inner planets are small. They have shorter orbits around the Sun and they spin more slowly. Venus spins backward and spins the slowest of all the planets.

All of the inner planets were geologically active at one time. They are all made of cooled igneous rock with inner iron cores. Earth has one big, round moon, while Mars has two very small, irregular moons. Mercury and Venus do not have moons.

‼️SHOW ALL STEPS‼️ If 14.4 grams of iron reacts with hydrochloric acid, how many grams of hydrogen gas will be produced?
Alex Ar [27]

Answer: 0.771 g of H_2 will be produced

Explanation:

To calculate the moles :

\text{Moles of solute}=\frac{\text{given mass}}{\text{Molar Mass}}    

\text{Moles of} Fe=\frac{14.4g}{56g/mol}=0.257moles

The balanced chemical reaction is:

2Fe(s)+6HCl(aq)\rightarrow 2FeCl_3(aq)+3H_2(g)  

According to stoichiometry :

2 moles of Fe produce = 3 moles of H_2

Thus 0.257 moles of Fe will produce=\frac{3}{2}\times 0.257=0.385moles  of H_2  

Mass of H_2=moles\times {\text {Molar mass}}=0.385moles\times 2g/mol=0.771g

Thus 0.771 g of H_2 will be produced
