A positive ion (cation) is formed by removing electron(s) from an atom or group of atoms until there are fewer electrons than protons.
A negative ion (anion) is formed when an atom or group of atoms gains electron(s) until there are more electrons than protons.
Only non-metals form negative ions - this ability (to gain electrons) is intrinsic to the nature of non-metals.
Only metals form positive ions - this ability (to lose electrons) is intrinsic to the nature of metals.
What else can I help you with?
What is a group of atoms with with a positive or negative charge?
A polyatomic ion is a group of atoms with a charge.
Are cations negative ions?
Yes, the cation is a positive ion; ex.: H+, Ca2+, (UO2)2+.
What are the charged particles formed called?
Negative charge: electrons Positive charge: protons
What are Molecules that carry positive or negative electrical charges?
Molecules that carry positive or negative electrical charges are called ions. Positively charged ions are called cations, while negatively charged ions are called anions. Ions are formed when atoms gain or lose electrons.
Is copper a negative ion?
No, copper typically forms positive ions by losing electrons to achieve a stable electron configuration. Negative ions are formed by gaining electrons.
What is a ionic compound formed from the negative ions of and acid and the positive ions of a base?
salt
What is a group of atoms with with a positive or negative charge?
A polyatomic ion is a group of atoms with a charge.
How do you find positive and negative charged ions?
Positive ions are formed when an atom loses electrons, resulting in a net positive charge. Negative ions are formed when an atom gains electrons, resulting in a net negative charge. In chemical reactions, ions can be identified based on their charge and presence of a positive or negative sign.
How are negative and positive ions made?
A negative ion (anion) is formed after gain of electrons in the atom.A positive ion (cation) is formed after loss of electrons from the atom.
What is formed when positive and negative ions attract each other?
When positive and negative ions attract each other, an ionic bond is formed. Ionic bonding refers to the complete transfer of valence electron between atoms.
How do positive and negative ions forms?
Atoms gain electrons to form negatively charged anions. Atoms lose electrons to form positively charged cations.
Are cations negative ions?
Yes, the cation is a positive ion; ex.: H+, Ca2+, (UO2)2+.
What is the difference between a negative and a positive?
positive ions carry positive charge and negative ions carry negative charge
Which of the following are always larger than the neutral atoms from which they are formed.. A. positive ions B. negative ions C. cations D. none of the above?
B. negative ions. Negative ions are formed when neutral atoms gain electrons, increasing their size due to the additional electron(s) while positive ions or cations are formed when neutral atoms lose electrons, reducing their size.
What kinds of charges can ions have?
Ions can have either a positive or a negative charge.
What is a repeating pattern of positive and negative ions held together?
An ionic solid. More specifically, the alternating positive and negative ions form an ionic lattice.
What are the charged particles formed called?
Negative charge: electrons Positive charge: protons
