Answer:
There are electrons in this atom.
Explanation:
Electron configuration of this atom: .
The electron orbitals of an atom are denoted as , , , , , etc. At any given time, an electron in this atom is located in exactly one orbital.
The electron configuration of an atom gives the number of electrons in each orbitals of this atom.
For example, in this atom, the superscript "" on the right of "" means that there are two electrons in the orbital of this atom. Hence, would translate to:
- The orbital of this atom contains electrons.
- The orbital of this atom contains electrons.
- The orbitals of this atom contain electrons.
Hence, there would be electrons in total in this atom.
Answer:
8) 45 volt
9) 8 ohms
100 volt
Explanation:
using ohms law all through
8) v = 3×15

I believe it is b. I hope this helps you
Answer:
Explanation:
Given parameters:
number of moles magnesium = 6.80mol
number of moles of chlorine = 13.56mol
To find the complete chemical formula, we should obtain the formula of the compound.
Mg Cl
Number of
moles 6.8 13.56
Dividing
by the smallest 6.8/6.8 13.56/6.8
1 2
The formula of the compound is MgCl₂
This is an ionic compound in which Magnesium loses two electrons that would be gained by Cl atoms requiring just an electron each to complete their octet.
