It depends on what you mean by 'higher energy'.
Carbon needs to have 8 electron in its outermost shell to have it completely filled, 4 more valence electrons than it has in the neutral for of carbon.
Carbon atoms have a total of six electrons. In a neutral carbon atom, these electrons are arranged with two in the first energy level (the innermost shell) and four in the second energy level, allowing for the formation of four covalent bonds with other atoms.
There are 2 energy levels in a Carbon atom. The first energy level consists of '1s' orbital, and the second energy level consists of the '2s' orbital and the '2p' orbital.
Carbon has 4 outermost electrons.
You shouldn't use terms like "outer level", because they're confusing. It could potentially mean at least two things, specified more precisely below. The highest occupied energy level of a ground state neutral carbon atom, the 2p level, has two electrons. The number of electrons in a ground state neutral carbon atom that have a principal quantum number of 2 (the highest associated with any electrons in such an atom) is four.
In its ground state, carbon does not have any electrons in the third energy level.
The valance energy level contains 4 electrons in carbon.
Carbon has four electrons in the outermost energy level, which is energy level two. It needs eight electrons to have this energy level filled.
K,L = 2, 4 Electron configuration 1s2, 2s2 2p2
Carbon has four electrons in the outermost energy level, which is energy level two. It needs eight electrons to have this energy level filled.
In a neutral carbon atom, there will be 4 electrons in the outer most valence shell.
Carbon has 2 energy levels. There are 6 electrons, 6 protons, and 6 neutrons.
4
carbon has 2 electrons in its first energy level and 4 in its secound energy level because carbons atomic number is 6. 4+2=6.
There are four electrons in the second energy level of carbon. Here's the electron configuration: 1s2 2s2 2p2 or [He] 2s2 2p2.
8
Carbon needs to have 8 electron in its outermost shell to have it completely filled, 4 more valence electrons than it has in the neutral for of carbon.
