Choose the answer that best completes the following statement: when an aluminum atom reacts so as to attain a noble gas electron configuration, choose the answer that best completes the following statement: when an aluminum atom reacts so as to attain a noble gas electron configuration, the atom gains five electrons. the noble gas configuration of argon is achieved. a 3- ion forms. the result is a configuration of 1s22s22p6. none of the above

The correct statement is : The atom gains five electrons.

Explanation:

Aluminum has the atomic number of 13.

The electronic configurations of aluminum is given:

So, in order to gain stability of noble gases aluminium ether have to gain 5 electrons or loose three elections.

By gaining five electrons its electron configuration gets same as that of the argon's electronic configuration.

So, the charge on the aluminium ion will be (5-).

1. Plasma is "the state..." because plasma is rarely natural on earth (only lightning strikes) and has the highest temp

gas is "particles move freely" they do move freely

liquid is "it expands to fill volume" they do not have definite boundaries so they fill up the container

solid is "it retains its shape" yup dis is pretty obvious ig

2.

I agree with your answers.

it wouldnt be hypothesis or theory because they are basically the same thing and they explain facts. fact would be the best answer

conduct experiments would be the most logical here because you can gain new knowledge from conducting experiments instead of the rest.
