What is the ion formed by iodine?
Iodine typically forms a negatively charged ion called iodide (I-).
What would happen if a positively charged sodium ion and a negatively charged ion came into contact?
The ionic compound sodium chloride is formed.
In a negetivly charged ion the number of electrons must be?
In a negatively charged ion formed from a single atom, the number of electrons must be greater than the number of protons in the ion.
What would happen if a positively charged sodium ion and negatively charged chlorine ion came into contact?
The ionic compound sodium chloride is formed.
What would happen if a positively charged sodium ion and a negatively charged chlorine ion came into contact?
The ionic compound sodium chloride is formed.
What type of ion is formed from a neutral atom when it gains electrons?
Negatively charged anions are formed.
What type of bond is formed by a positvely-charged and negatively-charged ion?
an ionic bond
What compare and contrast a hydrogen ion and a hydroxide ion?
A hydrogen ion (H+) is a positively charged ion formed when a hydrogen atom loses its electron. A hydroxide ion (OH-) is a negatively charged ion formed by the combination of a hydrogen ion and an oxygen atom. They are oppositely charged ions that combine to form water (H2O) in a neutralization reaction.
What is formed when atoms lose electrons?
A cation, which is a positively charged ion, is formed when an atom loses electrons.
Ion is formed when an atom loses an electron?
Yes, an ion is formed when an atom either loses or gains an electron, resulting in a net positive or negative charge, respectively. When an atom loses an electron, it becomes a positively charged ion, known as a cation.
What is Ammonium ion and Hydronium ion?
The Ammonium ion (NH4+) is the ion formed when ammonia (NH3) acquires an H+ ion from an acid. The hydronium ion (H3O+) when water acquires an H+ ion from an acid. It is not stable outside of an aqueous (water) environment.
What is formed when an atom gains or loses an electron?
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).
