How many electrons does the nickel ion contain in the compound NiS?
Nostrana [21]

There are 26 electrons in the nickel ion in the compound NiS.

<h3>How many electrons does the nickel ion contain in the compound NiS?</h3>

The number of electrons in a neutral Nickel atom is obtained from the atomic number of Nickel.

The atomic number of Nickel is 28, therefore, the neutral nickel atom has 28 electrons.

In  the compound NiS, nickel atom loses two electrons to to form the nickel ion.

Number of electrons left = 28 - 2 = 26

Therefore, there are 26 electrons in the nickel ion in the compound NiS.

In conclusion, nickel atom loses two electrons to form nickel ion in NiS.

A dark purple liquid is diluted by adding water.
alexandr402 [8]

Answer: The process is diffusion.

Explanation:

a dark liquid will have the highest concentration of dark purple atoms/molecules so it gives a concentrated colour.

when water is added to it, the colourless water molecules fill up the gaps between the purple particles and so their colour fades and becomes lighter and lighter as we add more water. see the image attached where imagine the red particles are water and the blue particles are purple particles. thats why the colour fades.
