the number of electrons in a valence shell is 8
there are two electrons the first shell hold
The K shell of an atom can hold up to 2 electrons.
Valence electrons are the total amount of electrons on the outermost shell of an atom. Meaning if the last shell has two, the valence electrons are two. But a complete valence shell would hold eight.
they "steal" electrons so that they can have a full outer shell. shells hold electrons and the outer shell's electrons are called valence electrons. valence electrons are the ones that do all of the chemical bonding. the right half usually steals electrons because(eg.) it uses less energy to take 3 than to give away 5. atoms are stablest with a full or empty outer shell, and then become ions. ions are charged elements. an atom only becomes an ion if a chemical bond is about to occur. those only occur if a compound is forming (sodium chloride(NaCl) is Na+1 and Cl-1 ,and they are charged because one valence electron is being shared or "stolen")
Is called a shell. The first shell around the nucleus can hold a maximum of two electrons. While the second shell can hold a maximum of eight electrons.

The K shell of an atom can hold up to 2 electrons.
P stands for Principal shell and it can hold 6 electrons.
Valence electrons are the total amount of electrons on the outermost shell of an atom. Meaning if the last shell has two, the valence electrons are two. But a complete valence shell would hold eight.
The first shell of Neon, known as the K shell, can only hold two electrons. The first shell of any chemical element can only hold two electrons.
The second shell can hold eight electrons.
Valence shell is outermost shell of an atom.It cannot hold more than 8 electrons.
There can be up to 18 valence electrons in a atom, these atoms are krypton, xenon, radon, and sometimes mentioned is ununoctium but is an "unknown element" so the element is not always mentioned

The first shell can hold a maximum of 2 electrons, the second shell can hold up to 8 while the third shell can also hold a maximum of 8.
