Sodium Chloride is placed in water, what happens to the sodium ions and chloride ions in the solution.

Which part of the atom is responsible for chemical bonding

Answers

The part of atom that is responsible for chemical bonding is electrons. The correct option is b.

Atomic chemical bonds are formed by electrons. They are subatomic particles with negative charges that move in distinct energy levels or shells surrounding an atom'snucleus.

Atoms interact with one another during chemicalprocesses to produce a more stable electron configuration.

To obtain a full outermost electron shell, sometimes referred to as the octet rule, atoms can either receive, lose, or share electrons. Atoms are able to form chemicalbonds, such as ionic bonds, covalent bonds, and metallic bonds, thanks to this interaction of electrons.

These bonds are crucial for the synthesis of molecules and compounds. The actions and configuration of electrons govern the chemistry and reactivity of elements.

Thus, the correct option is b.

Your question seems incomplete, the probable complete question is:

which part of the atom is responsible for chemical bonding?

a) Protons

b) Electrons

c) Neutrons

d) Nucleus

that would be the electron, because of the Octet Rule, electrons in an atom want to become stable by gaining, losing, or sharing electrons with other atoms until they have 8 valance electrons. Because of this, in a chemical bond atoms share electrons with eachother so noth can have 8 valance electrons and both can become stable.
