How is valence and reactivity related?
Valence electrons are the electrons on the outer shell of an atom. Valence electrons help to determine the reactivity of a substance because atoms do their best to "fill" their outer shell with 8 electrons, thus achieving a more stable energetic state. Different atoms have different numbers of valence electrons, which affects their reactivity. For instance, noble gases are inert because they possess a full set of valence electrons and don't need to "borrow" or "give away" electrons to have a full outer shell. Halogens, on the other hand, are 1 electron away from filling their outer shell, and are very reactive as a result (they attempt to "borrow" an electron with other atoms by forming a chemical bond).
How many electrons does each atom desire?
Atoms do not actually have desires as such, although the metaphor can be useful. Atoms are more stable when they have a full outer electron shell. The smaller atoms, hydrogen, helium, lithium, and beryllium, can obtain a full outer shell with only two electrons in it. The heavier atoms require 8 electrons to have a full outer shell. That is known as the octet rule (an octet is a set of eight).
Are atoms with more than 4 outer electrons are nonmetals?
No, but metals have more than three-fourths.
Which atoms will have their outer energy level filled with 2 electrons?
There are more than two such atoms. Perhaps there was a list of atoms you had to chose from. Anyway, two such atoms are beryllium and magnesium.
Are Atoms with more than 4 outer electrons are metals?
No, atoms with more than four outer electrons are generally not classified as metals. Instead, they tend to be nonmetals or metalloids. Metals typically have fewer than four electrons in their outer shell and tend to lose electrons to form positive ions, whereas nonmetals usually gain or share electrons. The classification of elements as metals or nonmetals is primarily based on their position in the periodic table.
What is the ability of an atom to borrow or lend electrons?
The ability of an atom to borrow or lend electrons is determined by its electronegativity. Atoms with higher electronegativity tend to attract electrons towards themselves, while atoms with lower electronegativity are more likely to donate electrons. This tendency influences how atoms form chemical bonds with each other.
Is it true that atoms with fewer that 4 outer electrons lend electrons?
Atoms with fewer than 4 outer electrons tend to lose electrons to achieve a stable electron configuration rather than lend them. This results in the formation of positively charged ions. Atoms with 4 or more outer electrons tend to gain electrons to fill their outer electron shells and form negatively charged ions.
What if the outer orbital is not full of electrons?
If the outer orbital is not full of electrons, the atom will likely form chemical bonds with other atoms in order to fill its outer orbital and achieve a stable electron configuration. This can result in the atom gaining, losing, or sharing electrons with other atoms to reach a more stable state.
Why do outer shells of atoms hold more electrons?
The outer shells of atoms can hold more electrons because they have higher energy levels compared to inner shells. These outer shell electrons are farther from the nucleus and experience weaker attraction forces, allowing them to occupy a larger electron capacity.
How is valence and reactivity related?
Valence electrons are the electrons on the outer shell of an atom. Valence electrons help to determine the reactivity of a substance because atoms do their best to "fill" their outer shell with 8 electrons, thus achieving a more stable energetic state.

Why is it important covalent bonds have a full outer shell?
Covalent bonds form when atoms share electrons to achieve a full outer shell, which makes them more stable. A full outer shell corresponds to the octet rule, which states that atoms are more stable when they have eight electrons in their outermost shell. By sharing electrons in covalent bonds, atoms can achieve this stable electron configuration.
Which two atoms will have their outer energy level filled with 2 electrons?
Helium (He) and Neon (Ne) will both have their outer energy level filled with 2 electrons.
Do atoms gain or lose electrons to achieve a stable electron configuration?
They can do either - and they will. This is the fundamental mechanism behind the science we know as chemistry. Or Yes, they do. Some want to borrow some and some want to loan some out. This is the fundamental mechanism behind the science we know as chemistry.

That is known as the octet rule (an octet is a set of eight).
are chemical bond energy relationship between outer electrons and neighboring atoms?
Yes, chemical bond energy results from the interactions between the outer electrons of atoms and their neighboring atoms. These interactions involve the sharing, transfer, or attraction of electrons to achieve a more stable configuration, leading to the formation of chemical bonds. The strength of the bond is determined by the nature of these interactions and the arrangement of atoms in the molecule.
What happens to electrons in the outer energy levels when two atoms form covalent bonds?
Electrons in the outer energy levels of two atoms are shared between them to form covalent bonds. This sharing allows the atoms to achieve a more stable electron configuration. The electrons are attracted to the nuclei of both atoms, holding them together in the bond.
Are atoms with more than 4 outer electrons are nonmetals?
No, but metals have more than three-fourths.
