Valence electrons can be both lost and gained during a chemical reaction, depending on the types of elements involved. For example, in ionic bonding, valence electrons are typically lost or gained to achieve a full outer shell. In covalent bonding, valence electrons are shared between atoms to complete their outer shells.

What is the number of electrons that are lost or gained or shared by an atom during the course of a chemical reaction?
The number of electrons lost, gained, or shared by an atom during a chemical reaction depends on its valence electrons and the goal to achieve a stable electron configuration. In ionic reactions, atoms can lose or gain electrons to achieve a full valence shell, while in covalent reactions, atoms share electrons to fill their valence shells.
What role do valence electrons play in formation of bonds?
Valence electrons are electrons on the outermost "level". And depending on its electron configuration, it plays a role in which if the atom requires to gain or lose electrons in order to become "stable", it can accept or give electrons to another atom in a chemical reaction.
Are exchanged or shared during the formation of a chemical bond?
Electrons are exchanged or shared during the formation of a chemical bond. In ionic bonds, electrons are transferred from one atom to another, leading to the formation of positive and negative ions. In covalent bonds, electrons are shared between atoms in order to achieve a stable electron configuration.
What does a valence shell have to do with chemical reactions?
The valence shell is the outermost shell of an atom and contains electrons involved in chemical reactions. The number of electrons in the valence shell determines an atom's reactivity and tendency to form chemical bonds with other atoms to achieve a full valence shell, following the octet rule. Chemical reactions often involve interactions between the valence electrons of different atoms to form new compounds.
What subatomic particles is lost or gained during a chemical reaction?
During a chemical reaction, electrons are the subatomic particles that are lost or gained. When an atom loses electrons, it becomes positively charged and when it gains electrons, it becomes negatively charged. This process is responsible for the formation of chemical bonds and the creation of new compounds.
Which electron on an atom is the most likely one to be removed during a chemical reaction?
The valence electron, which is the electron located in the outermost energy level of an atom, is the most likely to be removed during a chemical reaction. This is because valence electrons are involved in the formation of chemical bonds and determining an atom's reactivity.
What is an electron called in the outermost energy level?
They are called valence electrons, and they are responsible for an atom's chemical properties. During a chemical reaction, the valence electrons are the only part of an atom that participates.

In covalent bonds, electrons are shared between atoms in order to achieve a stable electron configuration.
Is the elecron configuration of an atom related to its tendency to give up or gain electrons during a chemical reaction?
Yes. If there are 1 to 3 valence electrons in an atom, then generally those elements will lose these electrons to attain noble gas configuration. If there are 5 to 7 valence electrons, then generally those elements will gain electrons to attain noble gas configuration.
Do non-metals gain electrons in chemical reactions?
Yes, non-metals can gain electrons in chemical reactions to achieve a stable electron configuration, typically by forming negative ions. This process is known as reduction, where the non-metal gains negatively charged electrons to fill its valence shell.
What does a valence shell have to do with chemical reactions?
The valence shell is the outermost shell of an atom and contains electrons involved in chemical reactions. The number of electrons in the valence shell determines an atom's reactivity and tendency to form chemical bonds with other atoms to achieve a full valence shell, following the octet rule. Chemical reactions often involve interactions between the valence electrons of different atoms to form new compounds.
Do alkali metals give up one valence electron during a chemical reaction?
Yes, it is correct.
What subatomic particles is lost or gained during a chemical reaction?
During a chemical reaction, electrons are the subatomic particles that are lost or gained. When an atom loses electrons, it becomes positively charged and when it gains electrons, it becomes negatively charged. This process is responsible for the formation of chemical bonds and the creation of new compounds.
Why did the protons did not participate during chemical bonding?
Chemical bonding only involves the outermost level of electrons, valence electrons. The actual reaction takes place far away from the nucleus of the atom where the protons are. There are reactions that involve the protons, though, but they are nuclear reactions, not chemical reactions. They are usually achieved through high-speed collision in labs.
Why are non valence electrons not involved in reactions?
Non-valence electrons are located in inner energy levels of an atom and are shielded by the valence electrons from interacting with other atoms during chemical reactions. Since they are closer to the nucleus and have higher energy levels, they are less likely to participate in bonding interactions with other atoms. Valence electrons, on the other hand, determine an atom's reactivity and are involved in forming chemical bonds.
