depends on the element
there are two electrons the first shell hold
A neutral atom will have the same number of electrons as protons. A neutral atom with 14 electrons will therefore have 14 protons, as the negative electrons balance the positive protons. In an ion (atom with a charge), the number of electrons does not match the number of electrons.
Oxygen has 8 electrons (assuming its charge is 0), and in the first shell ("closest" to the nucleus) there are 2 electrons. :)
In an oxygen atom with 2 electron shells and 6 covalent bonds, there are 8 electrons in total. The first electron shell can hold up to 2 electrons, and the second shell can hold up to 6 electrons, giving a total of 8 electrons in the atom.
Neon atom number 10: first shell (K) : 2 electrons second shell (L): 8 electrons all shells being filled up completely
Protons won't be found in an electron shell. They are concentrated in the nucleus.
The protons are in the nucleus. It's the electrons that are in the "shells" around the nucleus. There's just one electron in the third shell of the sodium atom.
firstly the protons are in the nucleus of an atom. there are 16 protons there. the number of electrons is the same as the number of protons. the electron arrangement is as follows: first shell-2 electrons second shell - 8 electrons third shell - 6 electrons this can also be written as 2,8,6
2 in the first shell .every shell after that can have a maximum of 8.
2
there are two electrons the first shell hold
There are 18 protons in an Aragon atom.

An atom of copper has 29 protons.
