Which element has 2 electrons in the 4s sublevel?

Which elements have 2 electrons in the 4s sublevel?
Ca
How many electrons are found in each sublevel?
Multiply the orbitals in that sublevel by 2. The s sublevel has one orbital and can contain 2 electrons. The p sublevel has three orbitals and can contain 6 electrons. The d sublevel has five orbitals and can contain 10 electrons. The f sublevel has seven orbitals and can contain 14 electrons.
What is the number of electrons in the third principal energy level in an atom having the electron structure 1s2 2s2 2p6 3s2 3p2?
The element with that electron configuration has 4 electrons in the third level. There are 2 electrons in the 3s sublevel and 2 more electrons in the 3p sublevel. This means 4 valence electrons total. This element is silicon (Si, #14).
What element has 2 electrons in the 1s sublevel and 4 electrons in the 2s level?
An element cannot have 4 electrons in the 2 s level. The s subshell can hold only TWO electrons. Carbon has 4 electrons in the 2p level, however, if that's what you meant.

Why can a p sublevel hold 6 electrons while the s sublevel can hold no more than 2 electrons?
because sublevel p has 3 orbital and each orbital can hold up to 2 electrons meanwhile sublevel s only has 1 orbital and each can hold 2 electrons therefore sublevel p can hold more
How many electrons are in the g sublevel?
There are 9 orbitals in a g sublevel. (there is 1 in an s sublevel, 3 in a p sublevel, 5 in a d sublevel, 7 in an f sublevel, 9 in a g sublevel, 11 in an h sublevel, etc.)
The element Mn has how many valence electrons?
In actuality Mn has SEVEN valence electrons, not really 2 as might be predicted. The reason for this is that Mn is [Ar]3d5 4s2, and as a transition element, not only are the 4s electrons available for bonding, but so are those in the d orbital. So, the 5 electrons in 3d and the 2 electrons in 4s are all considered as valence electrons.
How many valence electrons would an element with atomic number 56 have?
The element with atomic number 56 is barium, a group 2 alkaline earth metal. Its atoms have two valence electrons in the 6s sublevel.
How many electrons are in the 2p sublevel of carbon?
Carbon is the group 14, period 2 chemical element. Its electron configuration is 1s2 2s2 2p2. Thus, carbon has 2 electrons in its 2p subshell.
