A positive ion and a negative ion.
A positive ion and a negative ion. two oppositely charged ions
If a positive ion is attracted to a negative ion, they will come together and form an ionic bond. This bond is formed by the electrostatic attraction between the oppositely charged ions. This bond is typically strong and stable.
KClO4 has an ionic bond. In this compound, potassium (K) donates its electron to form a positive ion, while the perchlorate ion (ClO4) gains that electron to form a negative ion. The attraction between the positive and negative ions creates the ionic bond in KClO4.
No, sodium and chlorine do not form a covalent bond. They typically form an ionic bond, where sodium loses an electron to form a positive ion and chlorine gains an electron to form a negative ion, resulting in an attraction between the two ions.
Sodium and chlorine can form an ionic bond. Sodium easily loses an electron to form a positively charged ion, while chlorine gains an electron to form a negatively charged ion, leading to the attraction between the two ions to form an ionic bond.
Calcium and oxygen will form an ionic bond in the compound calcium oxide. Calcium will donate its two electrons to oxygen, creating a positively charged calcium ion and a negatively charged oxygen ion, which will attract each other to form the bond.
Selenium and bromine can form an ionic bond, where selenium, a nonmetal, gains electrons to become a negative ion, and bromine, a halogen, loses electrons to become a positive ion.
They form an ionic compound.
When anions and cations form bonds, they typically form ionic bonds. In an ionic bond, the cation (positively charged ion) is attracted to the anion (negatively charged ion) through electrostatic forces, creating a stable bond between the two ions.
The formation of an ionic bond with Hg2^2+ (mercury(I) ion) typically occurs when it reacts with an anion to achieve a stable electron configuration. The mercury atom loses two electrons to form the Hg2^2+ ion, which then is attracted to a negatively charged ion to form an ionic bond.
