A cation, which is a positively charged ion, is formed when an atom loses electrons.
To form a molecule, atoms can share, lose, and gain electrons
If atoms gain electrons, negatively charged anions are formed. If atoms lose electrons, positively charged cations are formed.
Cations are formed when neutral atoms lose electrons, leading to a positive charge. This loss of electrons results in a higher number of protons compared to electrons in the atom, creating an overall positive charge.
Molecules are formed when atoms lose electrons and then attach themselves to other atoms
Ions do not share electrons with other atoms. Ions are formed when atoms gain or lose electrons to achieve a stable electron configuration. Positive ions (cations) lose electrons, while negative ions (anions) gain electrons.
Most atoms have the ability to lose electrons, given the conditions are favorable, e.g. in a chemical reaction, but the ones that loose their electrons easiest are the ones with only a few electrons in their outer shell, such as the alkali metals and alkaline earth metals which only have 1 and two electrons, respectively.
Positive ions (or cations) are formed when atoms lose electrons
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.
When atoms or molecules gain or lose electrons, they are best described as becoming ions. Ions are charged particles that are formed through the process of gaining or losing electrons.
Ions are formed when atoms gain or lose electrons in their outer orbit/shell. Electrons are negatively charged so if they lose an electron they become positively (plus) charged.
The two types of ions are cations and anions. Cations are formed when atoms lose electrons, resulting in a positively charged ion, while anions are formed when atoms gain electrons, resulting in a negatively charged ion.
Atoms that gain or lose electrons become ions, not molecules. Ions are charged particles due to an imbalance of protons and electrons. Molecules are formed when atoms are bonded together by sharing electrons.
