in the third shell, an electron has more energy and is further from the nucleus
It represents the family the element is in.
electrons
valence electrons
4/3 * pi * (125 - 27)Improved answer with the same result:If the outer circumference is 10 times pi cm then its outer radius is 5 cm and its inner radius is 3 cm.outer volume - inner volume = volume of the sphere's shell(4/3*pi*53) - (4/3*pi*33) = 410.5014401 or 410.5 cubic cm to 1 decimal place
The outer shell of an atom is called the valence shell. It contains the valence electrons, which are involved in forming chemical bonds with other atoms.
An oxygen atom has six (6) electrons in its outer shell.

A neutral neon atom has 8 electrons in its outer shell. Neon has a total of 10 electrons, with 2 in the inner shell and 8 in the outer shell.

The valence shell is the outermost shell...and an atom can only have one outer shell.
The outer-most shell of an atom is called the valence shell. It is involved in forming chemical bonds with other atoms.
Electrons are found in an atom's outer shell. The outer shell, also known as the valence shell, is where the electrons involved in chemical reactions and bonding are located. The number of electrons in the outer shell determines the atom's chemical properties.
When an atom forms an ion, the outer shell of the ion will have gained or lost electrons to achieve a full valence shell. For cations (positive ions), the outer shell will have fewer electrons than the neutral atom. For anions (negative ions), the outer shell will have more electrons than the neutral atom.
