Answer:

The viscosity of the water will decrease. Surfactants disrupt intermolecular forces within a liquid. Viscosity is directly related to intermolecular forces. If intermolecular forces are decreased, viscosity should also decrease.

have a good day ! :)

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.

What is the electronic configuration of Au3+?

Anettt [7]

Answer:

$AU^{3+} : [Rn] 5f^3$

Explanation:

Writing electronic configuration of any element you should know atomic number of that element ,

and also electrons are filling according to their energy level and first electron is filled in the lower energy orbital

and it follows n+1 rule if n+1 is same for two orbital electron will go first in the lowest value of n.

writing electronic configuration of ion can be done like first for their neutral atom and then add or remove electron it will make things easy because there are also some eception case their you may do wrong.

$AU : [Rn] 5f^3 6d^1 7s^2$

remove three electron from outer most shell of AU

$AU^{3+} : [Rn] 5f^3$
