Within the core of the Sun, temperatures and pressures are high enough to fuse hydrogen atoms into helium, which is the Sun's main form of energy production. Assuming there was a slight mistake in where you have copied the results here the correct answer is the third option.
Hope this helps!
Answer:
3- is the charge and 8 dots on its Lewis dot structure.
Explanation:
Hello there!
In this case, since nitrogen is an element with five valence electrons (electrons on its outer shell), we infer that it needs three bonds to complete the octet, for which its charge, when forming nitride ions is 3-, which means it has received three electrons. Thus, when drawing the Lewis dot structure, it is evident that is will have 5+3 = 8 dots due to the electron reception.

Half-life is the time it takes for the radioactive material's mass to decrease by half.
So, half of 96 is 48
half of 48 is 24
half of 24 is 12
half of 12 is 6
96->48->24->12->6
You count how many arrows (->) there is.
Which is 4
Then you use the 12 minutes the question gave you to do:
12 divided by 4
= 3
So, one half-life (Or the time it takes for the radioactive material's mass to decrease in half) is 3 minutes
and every 3 minutes it will decrease by half.
What are the answer? For me to help you I need to see them
