The first element with an electron in the second energy level?
The first element with an electron in the second energy level is lithium. Lithium has three electrons, with two in the first energy level and one in the second energy level.
What is the neutral atom that has its first two energy levels filled has 1 electrons in its third energy level and has no other electrons?
This atom would be lithium (Li). It has 3 electrons, with 2 electrons in the first energy level and 1 electron in the third energy level.
What has 4 electrons in energy level n3?
An atom with 4 electrons in energy level n=3 could be an atom of lithium (Li). This is because lithium has an electron configuration of 2-1 in its first three energy levels (n=1, n=2, n=3) with 4 electrons, two in the first energy level, two in the second energy level, and one in the third energy level.
How many energy levels does lithium have?
there are two protons in the first level and one proton in the second level of Lithium
