Actually the atomic number tells you how many protons there are. And there are 6 elements with 2 electrons. You can find out that out by looking at a periodic table and looking at family 2. Im guessing you won't be able to find the element your looking for unless you know the number of nuetrons or even better the number of protons.

∙ 10y agoMost elements have two 2s electrons, as well as many other electrons. However, if you mean what element has two 2s valence electrons, that element would be beryllium, whose electron configuration is 1s22s2.

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.
What element has 2 electrons in the 1s sub-level 2 electrons in the 2s sub-level and 2 electrons in the 2p sub-level?
Carbon
If each orbital can hold a maximum of two electrons how many electrons can 2s hold?
17
How many element do the elements belonging two group IIIA have in there outermost shell?
Group 3 is part of the transition metal series. This means that the number of outer shell electrons the element has will depend on its oxidation state.
What is the total number of valence electrons in germanium atom in the ground state?
Germanium is in group 14 and in period 4 The s orbitals are 1S, 2s, 3S and 4S with two electrons in each - therefore 8 in all although only the two - those in the 4S - are valence electrons
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.
How many electrons can occupy the 2s subshell and 3d subshell?
Two electrons can occupy the 2s subshell, and 8 electrons can occupy the 3d subshell.

How would I find the electron configuration for carbon?
Carbon is the sixth element with a total of 6 electrons. In writing the electron configuration for carbon the first two electrons will go in the 1s orbital. Since 1s can only hold two electrons the next 2 electrons for C goes in the 2s orbital. The remaining two electrons will go in the 2p orbital. Therefore the C electron configuration will be 1s2 2s2 2p2.
How many electrons are held in the second energy level?
A total number of 8 electrons. Two in the 2s orbital and six in the 2p orbital
The outermost shell of the carbon atom contains?
two 2s electrons (2s2 ) and 2p electrons 2p2 so 4 all together
How many electrons to fill a 6 proton outer shell?
An atom with six protons would be a carbon atom. It would have six electrons, two in the first shell, the 1s orbital, and four in the second shell, two 2s electrons and two 2p electrons. The 2p orbital is further out than the 2s, so depending how detailed you want to be there are either four in the second shell, or two in the 2p orbital.
How many total electrons does an atom possess if it has the first two electron orbitals completed?
4 electrons. First orbital is the 1s which has 2 electrons. Second orbital is the 2s which has 2 electrons.
Which element have two protons and two electrons?
Helium
An element that has two outer electrons seeks to gain six more?
An element that has two outer electrons is carbon. Carbon would not use the energy to gain six more electrons when it can easily get rid of the two outer electrons.
