If neons atomic number is 10 how many electrons are in the outer energy level?

To determine the number of electrons in the outer energy level of an atom, you need to understand the electronic configuration of that atom. For neon (Ne), with an atomic number of 10, we need to examine the periodic table.

The periodic table is organized in a way that the elements in the same column, called a group, tend to have similar chemical properties. Neon belongs to Group 18, also known as the noble gases.

The noble gases have a complete outer energy level, which means they have stable electron configurations. In particular, neon has two electrons in its first energy level and eight electrons in its second energy level. Since the outermost energy level is also the second energy level, neon has a total of 8 electrons in its outer energy level.

So, in the case of neon (Ne), it has 8 electrons in its outer energy level.
