Assuming you are talking about the electrons in their shells (not the displaced ones):
It depends on the distance of those electrons from the nucleus. For example electron in the outer shell of potassium (K) is further away form the nucleus than electron in the outer shell of sodium (Na).
It means that potassium can lose this electron in outer shell easier than sodium does, and therefore is more reactive than sodium.

What is the energy level farthest away from the nucleus of the atom that holds 8 or more valence electrons?
The valence electrons of an atom are those electrons that are in its outer energy shell or that are available for bonding. The electrons more loosely held by the nucleus - are the ones that are gained, lost or shared.
What is the effect of electrons held loosely?
__________ electrons are loosely held to a positive nucleus.
Describe how the atoms in water are held together.?
Each hydrogen atom is bonded to the oxygen atom in a covalent bond, in which they share valence electrons.
How can you explain the fact that lanthanides are highly electropositive and metallic?
All have few outer energy level electrons which are loosely held by the atom.
What do delocalised valence electrons moving between nuclei do?
Delocalized valence electrons moving between nuclei become detached from their parent atom. The metal is held together by the strong forces of attraction between the delocalized electrons and positive nuclei.
Electrons that are held most loosely in an atom are called what?
The electrons in the valence band, this can be 1 to 8 electrons (in the s and p orbitals of the outer shell) depending on the element.
Is it true the valence electrons are those electrons most loosely held by the atom?
yes it is true, they are the outermost electrons and sometimes get "stolen" by other elements creating an ion
What is the energy level farthest away from the nucleus of the atom that holds 8 or more valence electrons?
The valence electrons of an atom are those electrons that are in its outer energy shell or that are available for bonding. The electrons more loosely held by the nucleus - are the ones that are gained, lost or shared.
What happens when one or more valence electrons are transferred from one atom to another?
This is the loaning (by one atom) and the borrowing (by another atom) of a valence electron or electrons that creates a chemical bond. This type of bond is the ionic bond where one atom loans (or gives up) and the other borrows (or takes) an electron or electrons. In the other bond type, the covalent bond, the two atoms involved share electrons.
The electrons farthest from the nucleus or most loosely held are called?
the electrons on the last shell of an atom are called valency electrons.
Are the valence electrons held most tightly by the atom?
Valence electrons are the electrons least tightly held by the atom and by definition are the electrons in the outermost shell of the electron and are highest in energy. They are the electrons that often contribute to an elements reactivity and in the case of Sodium, which as one valence electron in its ground state, it "gives up" its electron when it comes in contact with water.
Valence electrons are those?
Valence electrons are those that exist in the highest main energy level in the last shell of an atom.
What is the effect of electrons held loosely?
__________ electrons are loosely held to a positive nucleus.
What parts of an atom participate in chemical reactions?
When an element reacts with another element, they form a compound. How a compound is formed has to do with the number of valence electrons. The valence electrons are the electrons which are held in the outer most energy level.
Describe how the atoms in water are held together.?
Each hydrogen atom is bonded to the oxygen atom in a covalent bond, in which they share valence electrons.
What is the outer most energy level of an atom?
This is the valence shell and is involved in bonding e.g. the sharing or loss of electrons to form a molecule or giant structure. Inner shells do not take part in bonding though their shielding effect and repulsion does affect the loss and gain of electrons from this shell.
How can you explain the fact that lanthanides are highly electropositive and metallic?
All have few outer energy level electrons which are loosely held by the atom.
