electrons
In the normal sense of "react", no parts meet: The nuclei remain distinct but electons may be shared.
The outermost electrons, located in the atom's electron cloud, determine how it will react with other atoms. These electrons are involved in chemical reactions as they interact with electrons from other atoms to form chemical bonds.
Valence electrons, the are on the outermost layer of the atom
Atoms physically interact with each other through various forces such as electromagnetic forces, strong nuclear forces, and weak nuclear forces. These forces can cause atoms to attract or repel each other, leading to the formation of chemical bonds or interactions.
Valence electrons are responsible for reacting and bonding with other elements. These are the electrons in the outermost energy level of an atom and determine the atom's ability to form chemical bonds with other atoms.
The outermost shell, or valence shell, of an atom is responsible for forming bonds with other atoms. The number of electrons in this shell determines an atom's reactivity and its ability to interact with other atoms to form bonds.
The outermost electrons of a magnesium atom, located in its valence shell, interact with other atoms during chemical reactions. These electrons are responsible for determining the atom's reactivity, making magnesium more likely to form ionic compounds by losing two electrons to achieve a stable electron configuration.

While a lone oxygen nucleus might exist under extreme conditions, if allowed to interact with other atoms at the temperatures at which chemical bonds can form, that oxygen nucleus would immediately take electrons from other atoms until it formed a neutral atom.
Bonding between atoms occurs at the valence electron level. Core electrons and the atomic nucleus are unaffected.
When two atoms with a large difference in electronegativity interact, one atom will pull the shared electrons toward itself more strongly than the other atom. This results in the formation of an ionic bond, where one atom becomes positively charged (cation) and the other becomes negatively charged (anion).
Electrons are the part of an atom that is most directly involved in chemical bonding. They are responsible for the formation of bonds between atoms by being shared, transferred, or attracted to other atoms.
Valence electrons are responsible for reacting and bonding with other elements. These are the electrons in the outermost energy level of an atom and determine the atom's ability to form chemical bonds with other atoms.
When two atoms come into contact, it is their electron clouds that interact. Electrons from each atom repel each other due to their negative charge, creating a repulsive force that prevents the atoms from physically touching.
