<h3><u>Answer;</u></h3>
3p34s23d7
<h3><u>Explanation</u>;</h3>
- Electrons in an atom are contained in specific energy levels that are different distances from the nucleus.
- Within each energy level is a volume of space where specific electrons are likely to be located, called orbitals. Orbitals are of different shapes, denoted by a letter (s, p, d, f, g).
- S-orbital takes a maximum of two electrons, p-orbital take a maximum of six electrons, d-orbital takes a maximum of 10 electrons, and so fourth.
- The electron filling pattern takes; 1s, 2s, 2p, 3s, 3p, 4s, 3d, 4p, 5s, 4d, 5p.........
- Therefore; in this case after 3p3, we then go to 4s, with 2 electrons, then 3d which takes 7 electrons.
The answer for this one is a
Answer:
8.13x10^22 molecules
Explanation:
We can use the Avogadro's number(6.022 x 10^23 units / mole)
2.30 g NH3 (1 mol / 17.03 g ) (6.022 x 10^23 molecules / 1 mol ) = 8.13x10^22 molecules
