Answer:

Correct answer is B. Three electrons are gained, creating Al ^ -3

Explanation:

Aluminum in its valence shell has 3 electrons, this shell can have a maximun of 6 electrons. Then, to fill its valence shell, 3 electrons must be gained, and then the valence shell would have 6 electrons and would be complete.

If 3 electrons are gained, then Aluminum, would have a charge of -3, since each electron gained gives negative charge to the atom.

Al^ -3 is a ion of aluminum with charge -3.

Find the mass of a 52.2N bucket.

Goshia [24]

Answer:

m = 5.22 kg

Explanation:

The force acting on the bucket is 52.2 N.

We need to find the mass of the bucket.

The force acting on the bucket is given by :

F = mg

g is acceleration due to gravity

m is mass

$m=\dfrac{F}{g}\\\\m=\dfrac{52.2}{10}\\\\=5.22\ kg$

So, the mass of the bucket is 5.22 kg.

Select all that apply. There MIGHT be more than one.

I believe the answer to your question is “Lithosphere plate boundaries”

The planet Earth is covered by a layer formed by land and rocks called the earth's crust or lithosphere. This crust is not smooth and uniform, but rather irregular and composed of tectonic plates, also called lithosphere plates. These plates are not fixed as they are under the magma (high temperature molten rock).

Hope this helps!:)
