sodium has one valence electron
Yes, if the orbital is the outermost one that includes the valence electrons. Aluminum, for example, is such an atom, as is boron.
As a neutral atom, sodium possesses 1 electron in its outermost (3rd) energy level. As a 1+ ion, it possesses 8 electrons in its second energy level, forming an octet, which is the optimum number of electrons for sodium to possess in its outermost energy shell.
The outermost electrons, meaning the ones in the valence shell of the atom.
Electrons in the outermost shell are valence electrons!
The electrons on the outermost energy level of the atom are called valence electrons.

Valence electrons are electrons in the outermost shell (or outermost energy level or outermost orbital) in an atom. Noble gases have 8 valence electrons. But helium (a noble gas) has only 2 valence electrons.

Covalent bonds are formed when atoms share electrons. Let's take hydrogen for example. To be the most "happy" atoms want their outermost orbital full of electrons. Hydrogen has only one electron in its 1s orbital, but the 1s orbital can hold two electrons. Hydrogen wants two electrons to be "happy" so it will do what it takes to get them. If a hydrogen atom bumps into another hydrogen atom they can both become "happy" as each atom will share its electron with the other atom, giving each a full outermost orbital with the help of the other atom's electron. This is what creates the bond in covalent bond as the hydrogen atoms are "happier" together with a full orbital than they would be with a half-full orbital apart.
Valence electrons are the electrons in the outermost shell of an atom. The ones in the inner shell are known as core electrons.
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 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
