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 else can I help you with?
What is the effect of electrons held loosely?
Electrons held loosely can lead to a material exhibiting good electrical conductivity since they are free to move in response to an applied voltage. This is seen in metals where the valence electrons are not strongly bound to the atomic nucleus.
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.
The valence electrons are those electrons most tightly held by the atom?
Valence electrons are the electrons in the outermost energy level of an atom, and they are involved in bonding with other atoms to form molecules. These electrons are most loosely held by the atom, as they are farthest from the nucleus and have the highest energy.
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.
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

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 the electrons in the outermost energy level of an atom. They are involved in chemical bonding and determining an element's reactivity.
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.
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 parts of an atom participate in chemical reactions?
Electrons are the parts of an atom that participate in chemical reactions. Specifically, it is the outermost electrons, known as valence electrons, that are involved in forming chemical bonds with other atoms.
The force of attraction by group 1 metals for their valence electrons is?
The force of attraction by group 1 metals for their valence electrons is weak. This is because group 1 metals have a single valence electron that is loosely held and easily lost to form positive ions.
