How many orbitals occur in the 2 electron shell?
The second shell has a total of four orbitals. It first has a subshell designated s, which has one orbital and holds two electrons.
How many sublevels are contained in the second shell N 2 of a given atom?
So since the shell number is two, that means that there’s two possible sub levels that exist.
How many electrons can each of the following orbitals hold?
Any orbital can hold a maximum of 2 electrons with opposite spin. The first shell has one 1s orbital and holds 2 electrons. The second shell holds 8 electrons; 2 in a 2s orbital and 6 in three 2p orbitals. The third shell holds 18 electrons; 2 in a 3s orbital; 6 in three 3p orbitals; and 10 in five 3d orbitals.
What is the total number of electrons in the second principal energy level of a nitrogen atom in the ground state?
What is the total number of electrons in the second principal energy level of a nitrogen atom in the ground state? 26.
What is the total number of electrons in the second principal energy level of an oxygen atom in the ground state?
Oxygen has eight electrons. The first two electrons will go in the n=1 level. Two is the maximum number of electrons for the level so the other electrons will have to go in a higher energy level. The n=2 level can hold up to eight electrons so the remaining six electrons will go in the n=2 level.
How many electrons are in the second principal energy level of sodium?
Sodium has 11 electrons. The first two fill the innermost energy level. The second energy level is also full, holding eight electrons and one electron remaining in the outer energy level. It is the number of outer electrons that give an element its chemical properties.
