there is no such element

There are 7, 8 and 10 protons in nitrogen, oxygen and neon respectively. Neon has 8 valence electrons and is stable. Nitrogen and oxygen have 5 and 6 valence electrons respectively are are reactive.
An oxygen atom has two valence electrons.
Not necessarily. The atomic number is the same amount as the protons found in a certain element. remember that the number of protons are equal to the number of electrons as well. EX - Calcium's atomic number is 20 so therefore there are 20 protons and 20 electrons in the element. The atomic number also helps you find any valence electrons EX- oxygen's atomic number is 8 so you have 2 electrons filling the 1st orbital and 6 filling the 2 orbital. but the 2nd orbital is supposed to have 8 electron so there are 6 valence electrons.
Neon has 0 valence electrons and so there cannot be any element with fewer valence electrons.

There are 8 neutrons in oxygen element because the no. of electrons are equal to the number of protons and oxygen element contain 8 electrons.
oxygen is a element one the periodic table, as such it is made up of protons electrons and neutrons. so there are protons in oxygen but there is not oxygen in protons.
A neutral oxygen atom has eight electrons, two in the first energy level, and six in the second energy level, which are the valence (not covalent) electrons. You can tell how many electrons a neutral atom has by looking at that element's atomic number. The atomic number is the number of protons in the nuclei of the atoms of that element. In a neutral atom the numbers of protons and electrons are equal. So the element oxygen has the atomic number 8, and in a neutral oxygen atom, there will be 8 protons and 8 electrons.

Oxygen has 2 electrons in the innermost orbital and 6 in the outermost (valence) orbital.
Oxygen has 8 protons and electrons; six electrons are valence electrons.Depending on the natural isotope oxygen has 8, 9 and 10 neutrons
