1. option B

2. ground state Fe :  [Ar] 4s² 3d⁶

<h3>Further explanation</h3>

Aufbau rule

<em>Electrons occupy orbitals of the lowest energy level</em>

Charging electrons in the sub-shell uses the following sequence:  

1s², 2s², 2p⁶, 3s², 3p⁶, 4s², 3d¹⁰, 4p⁶, 5s², 4d¹⁰, 5p⁶, 6s², etc.  

So the correct choice of answer is B.

Ground state is the state of electrons filling skins with the lowest energy levels.

Excited state is the state of electrons which occupy a higher energy level

The atomic number of Fe = 26, so electrons=26

Ground state configuration of Fe : [Ar] 4s² 3d⁶ or

1s², 2s², 2p⁶, 3s², 3p⁶, 4s², 3d⁶

What magma would have formed from the partial melting of mantle material?.
BabaBlast [244]

Answer:

Basaltic magma is formed through dry partial melting of the mantle. The mantle lies just below the crust of the earth. Basalts make up most of the ocean’s crust; this is why basaltic magma is typically found in oceanic volcanoes. See also what substances are emitted from fumaroles? What type of melting produces most basaltic magmas?

PLEASE HELP WHAT IS THE CORRECT ANSWER (if possible let me know why)
ANTONII [103]

Answer:I’m not 100% sure but I think it’s the first answer.

Explanation:

The pressure would increase as the molecules are pushing out word more and more, leading to more space being taken and more pressure. But then again, I’m not sure. I’m just a freshman with below average grades.
