What else can I help you with?
What is true about all anions?
Atoms are not anions. An atom is an electrically neutral particle with equal numbers of protons and electrons. An atom becomes an anion by gaining more electrons, so becoming negatively charged.
When atoms lose electrons in an ionic bond what do they become?
These atoms become anions.
Do all atoms that are anions have more electrons than protons?
Atom that are anions have two more electrons than it has in protons.
How do the sizes of cations and anions relate to the atoms they form from?
Cations are formed when atoms lose electrons and hence are smaller in size than the corresponding atoms. Anions are formed when atoms gain electrons and hence are larger in size than the corresponding atoms.
Radioactive isotopes have excess electrons?
No (this is valid for neutral atoms); anions have excess electrons.
Do ions have more electrons than the atoms from which they were formed?
of course, ions are formed by loosing (cations) or gaining (anions) electrons. anions have more electrons than the atom from which it is formed.
Why are anions always larger than the atoms from which they are form?
When electrons are added into the outer shell repulsion occurs, to minimize the repulsion the electron cloud expands.
Do in ionic bonding atoms loose or gain electrons?
Actually both. Atoms gain electrons to form negatively charged anions whereas when atoms lose electrons positively charged cations are formed. Ionic bond is the force of attraction between cations and anions
What is it called when gain of electrons or H?
Gain of electrons form anions (negative charged atoms).
What kind of atoms gain electrons?
Generally non-metals gain electrons and form anions.
What are atoms that tend to pick up electrons in a reaction called?
Anions
How do positive and negative ions forms?
Atoms gain electrons to form negatively charged anions. Atoms lose electrons to form positively charged cations.
