They can be both. In sodium there is a single unpaired valence electron. In magnesium there are two valence electrons and they are paired.

What is so special about a valence electron?
Valence electrons are the electrons in the outermost shell of an atom. These electrons are important in bonding and magnetism. For example, carbon has 4 valence electrons. It can make 4 covalent bonds to fulfill the octet rule. Also, if an atom has unpaired electrons, it is called paramagnetic and if an external magnetic field is applied, it will be attracted. If all of the electrons are paired, it is diamagnetic and will be repelled by an external magnetic field.
Where on the periodic table do elements with 3 unpaired electrons appear?
The atoms of the elements in Group 13 (IIIA), the boron group, have three valence electrons, all of which are unpaired. The atoms of the elements in Group 15 (VA), the nitrogen group, have five valence electrons, three of which are unpaired.
How many electron unpaired is in rubidium?
2 Valence Electrons
Which group of elements forms bonds by using their six valence electrons?
The group 16 elements have 6 valence electrons. However, they generally only have two unpaired electrons available for bonding.
How many single or lone pair of electrons nitrogen have?
There are 3 unpaired electrons in an isolated nitrogen atom, the nitrogen molecule has none.
What factor dertemines that an oxygen atom can form two covalent bonds while a carbon atom can form four?
It is the number of unpaired electrons in their valence shells. Oxygen has two unpaired valence electrons and carbon has four unpaired valence electrons.
How many unpaired electrons are there in a ground state fluorine atom?
There should not be any unpaired valence electrons in a pure sample of Fe2O3: This substance is composed of Fe+3 cations and O-2 anions, in which all of the originally unpaired valence electrons in Fe and O atoms have become paired. Since Fe is a transition element, there may or may not be unpaired non-valence electrons in its inner shells.
How many valence electrons are in o?
O - Oxygen has 6 valence electrons.
In the Lewis symbol for a fluorine atom there are paired and unpaired electrons.?
Yes. That is true. There are 3 pairs of electrons, and 1 lone unpaired electron.
Does xenon have one valence electron with neutral?
No. there are no unpaired electrons in xenon. In neutral form, xenon will have 8 valence electrons.

How many unpaired electrons are in the boron atom?
In the element bromine (Br), there is only 1 unpaired electron. It has 7 valence electrons, so 3 pairs, plus an unpaired electron.
How many electron unpaired is in rubidium?
2 Valence Electrons
How many unpaired electrons are in Tc?
Technetium has 43 protons and electrons.
How many electrons would a phosphorus atom have in its Lewis Dot Structure?
5 electrons where two electrons are paired and three are unpaired
The reactivity of an atom arises from what?
the existence of unpaired electrons in the valence shell. :)
