This is half true. An ion is formed when an atom loses OR gains an electron. When it loses an electron it's called cation because it has a positive charge, and if it gains an electron it's called anion because it has a negative charge.
An atom can become an ion by either gaining or losing electrons. If it gains electrons, it becomes an anion. If it loses electrons, it becomes a cation. An ion is merely an atom with a charge, either positive or negative.
It depends on the exact situation. Probably ions Well this answer is vaguely correct. When an atom gains or loses an electron it becomes an ion. Ions with a net positive charge are called cations and ions with a net negative charge are anions. This allows for an ionic bond to occur. An ionic bond occurs when an anion binds with a cation.
An ion is a charged particle that is formed when an atom gains or loses electrons. The correct ion out of the options you provided is 4. Cl1, which represents a chloride ion that has gained one electron to acquire a negative charge.
If an atom gives one or more electrons as a result positive ion is formed. The reason is that an electron is negatively charged and normally an atom is neutral. if it gives electrons then positive ion is formed which is more likely to take electron to become neutral.
it becomes a charged ion loose = positive gain= negative
gains or loses an electron.
An ion is formed when an atom gains or loses an electrons or electrons. If it gains an electron, it becomes an anion, and if it loses an electron it becomes a cation.
An atom forms an ion when it gains or loses an electron. If an atom gains an electron, it becomes a negatively charged ion (anion). If an atom loses an electron, it becomes a positively charged ion (cation).
An ion is formed when an atom gains or loses an electron
The symbol for the cation formed when a potassium atom loses one electron is K+, and is named the potassium ion.
A positive ion is formed when atoms lose electrons. When a cell gains an electron it becomes negative
An Ion. More specifically if it gains an electron it becomes an anion and it it loses an electron it becones an cation (pronounced Kat-ion)
Removal of an electron from an atom leaves a positively charged ion.
K+ ions
A positive ion is formed when atoms lose electrons. When a cell gains an electron it becomes negative
When a helium atom loses an electron, it forms a helium ion which is positively charged because it has one less electron than protons. This helium ion is written as He+.
The charge on an ion formed by a sodium atom is +1. Sodium readily loses one electron to achieve a stable electron configuration, resulting in a positively charged ion.
