This valence shell has the valence electrons.
Electrons
Electrons belong in the outermost shell of an atom. They are negatively charged particles that orbit around the positively charged nucleus of an atom in specific energy levels known as shells or orbitals.
the valence shell is the outermost shell of an atom that has free electrons for taking part in chemical reactions... the valence shell of sodium has one free electron
Valence electrons are the electrons in the outermost shell of an atom. The ones in the inner shell are known as core electrons.
The outermost occupied energy shell of an atom is the valence shell, and it varies depending on the atom. It can be determined by looking at the period the atom is in on the periodic table.
The question is somewhat vague. If the question were written as an atom contains seven electrons in the outermost energy level and that outermost shell is a p-shell then the atom is a halogen. If the atom contains seven electrons in the outermost energy level and that outermost shell is a d-shell or f-shell then the atom is a metal.
There is no Iodone atom, there is however an Iodine atom that has seven valence electrons or seven electrons in outermost shell.
the valence shell
The valence shell is the outermost shell...and an atom can only have one outer shell.
Valence electrons are the electrons in the outermost shell of an atom. The ones in the inner shell are known as core electrons.
The outermost shell of an atom is determined by the number of electrons it can hold, which is based on the atom's position in the periodic table. Atoms tend to fill their outermost shell with electrons to achieve stability, following the octet rule for main group elements. The outermost shell is also known as the valence shell and is responsible for an atom's chemical behavior.
Electrons in the outermost shell are called valence electrons.
