ANSWER:
all of them
Explanation:
preciseness is measured by how many decimal places are used not by accuracy. since all of these are to the same decimal place they are all equally precise even if they are inaccurate.
Here is your answer:
Theirs 12 protons, 12 electrons, and 14 neutrons!
Reason: When you look at the atomic number for any element on the table with all of the elements that's how many protons, and electrons their are in the substance (or element) you find how many neutrons by rounding the number under the atomic number which will equal 14!
Your answer is 12:12:14

Answer:
<u>1)Thus based on the diagram , the values of principle quantum number that can be assigned to the electrons are : 2,3 and 4.</u>
<u>2)This quantum number tells us the shell in which an electron is present and how far it is roughly from the nucleus.</u>
Explanation:
According to the rules of electron filling in subshells in quantum mechanics , <em>Aufbau's principle states that :</em>
<em>"An electron must be filled in a lower energy state or subshell and then higher. If they have the same energy , the one with lesser principal quantum number will be filled first."</em>
Thus ,
The series of filling goes like:
Thus , the subshells in the given information have 1,3 and 1 orbitals respectively. Thus it has to be which is possible in two cases :
1)Thus based on the diagram , the values of principle quantum number that can be assigned to the electrons are : 2,3 and 4.
2)This quantum number tells us the shell in which an electron is present and how far it is roughly from the nucleus.
