The valence electrons are located in an atom's outermost energy level
<h3>Further explanation </h3>
In an atom, there are levels of energy in the shell and subshell
This energy level is expressed in the form of electron configurations.
Electrons fill the orbitals based on the Aufbau principle, namely the filling of electrons starts from the lowest energy level
Usually used in describing Lewis structures, placed around the element
Each orbital in an atom consists of 4 quantum numbers : n, l, ml, ms
Each electron has a different quantum number and this conforms to Pauli's rule: no electrons have the same 4 quantum numbers
Valence electrons are electrons used in a chemical bond , and in an atom's outermost energy level
Noble gas has a stable electron configuration of 8 valence electrons which guides the formation of chemical bonds called the octet rule
The correct answer is C.
On the left:
2 carbon+ 2 oxygen+ 2 oxygen
On the right:
2 carbon+ 4 oxygen (remember to multiply the coefficient and subscript)
Um definitely under .00001
Explanation:
I think the answer is B and A
i believe the answer is success of a policy. if this was correct please mark brainliest and lmk if you have any more questions x
