Answer is: chromium (Cr).
Chromium with atomic number 24, it means it has 24 protons and 24 electrons.
Electron configuration of chromim atom: ₂₄Cr 1s² 2s² 2p⁶ 3s² 3p⁶ 3d⁵ 4s¹.
In chromium, half full d-sub level (3d) is more stable than a partially filled d sub-level (3d⁴), thai is why an electron from the 4s orbital goes to a 3d orbital.
the correct answer is option d.
6.67*10-3 hrs
A. Lowering the temperature.
I hope this helped!
Answer:
Explanation:
The oxidation state of S is (-2) and that of Mg is (+2) since Mg loses two electrons to S
Answer:
3.01×10²³ atoms of calcium
Explanation:
number of moles = number of atoms/Avogadro's constant
n = N/NA
N = n×NA = 0.500 mol×6.02×10²³ mol^-1
N = 3.01×10²³ atoms of calcium
