An ionic bond is formed from a cation and anion.
A cation + anion =
A. negative ion
B. positive ion
C. neutral atom
B. positive ion
explain?
In an ionic bond, a cation (positively charged ion) and an anion (negatively charged ion) are attracted to each other due to the electrostatic force between their opposite charges.
A cation is formed when an atom loses one or more electrons, resulting in a net positive charge. This can occur when an atom has a relatively low electronegativity and easily donates electron(s) to another atom.
An anion is formed when an atom gains one or more electrons, resulting in a net negative charge. This can occur when an atom has a relatively high electronegativity and easily attracts electron(s) from another atom.
Therefore, the combination of a cation (+ charge) and an anion (- charge) results in the formation of an ionic bond, which creates a compound with a balanced overall charge.
A cation is a positively charged ion, while an anion is a negatively charged ion. Therefore, when a cation and an anion combine, the result is an ionic bond.
The correct answer is:
B. positive ion
To determine the answer, we need to understand the charges of cations and anions.
A cation is an ion that has lost electrons, giving it a positive charge. Cations are formed by metals. For example, sodium (Na) can lose one electron to become a sodium cation with a +1 charge (Na+).
An anion is an ion that has gained electrons, resulting in a negative charge. Anions are generally formed by nonmetals. For example, chlorine (Cl) can gain one electron to become a chloride anion with a -1 charge (Cl-).
When a cation and an anion come together, their opposite charges attract each other, and they form an ionic bond. The resulting compound is neutral overall because the positive charge of the cation balances out the negative charge of the anion.
Therefore, the correct answer is C. neutral atom.
