The first shell of an atom can hold 2 electrons. This does not mean that all atoms do have 2 electrons in their first shell. The exception is hydrogen (atomic number = 1) which has only 1 electron in its first shell before reacting with other atoms. Larry Mike Domingo 09072626008
It holds 32 elecctrons. Formula: 2n^2 n= orbital # Process: n^2= 4^2=16 16*2=32 :)
2 electrons can be held in a atoms first energy level
The first energy level may hold only 2 electrons.

First energy level can hold 2 electrons.Second energy level can hold 2 + 6 = 8 electrons. Total = 10 electrons.
valence electrons are the electrons in the outermost energy level
An atom has multiple energy levels. When an atom has more electrons than it can fit into an energy level, then it puts them into the next higher energy level.

What is the neutral atom that has its first two energy levels filled, has 5 electrons in its third energy level, and has no other electrons? Enter the name of the element, not the abbreviation.
2 electrons
First energy level can hold 2 electrons.Second energy level can hold 2 + 6 = 8 electrons. Total = 10 electrons.
An atom with seven electrons will have five electrons in the second energy level.
There are 8 electrons in the third energy level of a calcium atom.
A boron atom has three electrons in its second energy level.

the largest number of electrons an atom of helium can have is 2, because it is in the first period, which means it can only have one energy level, which has a maximum capacity of two electrons
