they have lost some electrons
Atoms that have lost electrons are called ions. When an atom loses electrons, it becomes positively charged because it now has more protons than electrons.
An atom that has lost valence electrons is called a cation. This causes the atom to have a positive charge due to having more protons than electrons.
An ion can be either negative or positive, depending on whether it has gained or lost electrons. A negatively charged ion, or anion, has gained electrons, while a positively charged ion, or cation, has lost electrons.
An ion is an atom or molecule that has gained or lost electrons, giving it a positive or negative charge, respectively. This charge allows ions to participate in chemical reactions by forming bonds with other ions or molecules. Ions play a crucial role in various chemical processes, such as electrolysis and ion exchange.
They are electrons in the outermost energy level of an atom. They are the electrons that are either shared, lost, or gained in the proccess of forming chemical compounds
Ionization level refers to the number of electrons that an atom has lost or gained, resulting in the formation of an ion. An atom with a positive ionization level has lost electrons and becomes positively charged, while an atom with a negative ionization level has gained electrons and becomes negatively charged.
Calcium typically loses 2 electrons to achieve a stable electron configuration, forming a Ca2+ ion. This results in a full outer energy level (valence shell), similar to the noble gas configuration of argon.

Electrons are lost when forming a xenon ion because xenon, a noble gas, tends to lose electrons to achieve a stable octet configuration in its outer energy level. Xenon can lose up to 8 electrons to form Xe2+ or Xe4+ ions.
The electron is negative (-), the cation is positive (+).
Different charges result from the loss of one or more electrons, or the gaining of one or more electrons forming ions. Atoms that lose electrons develop a positive charge equal to the number of electrons lost. Atoms that gain electrons develop a negative charge equal to the number of electrons gained.
If an object has a positive charge, it has lost electrons and now has more protons than electrons. This excess of positive charge causes the object to repel other positively charged objects and attract negatively charged objects.
Atoms that have lost electrons are called ions. When an atom loses electrons, it becomes positively charged because it now has more protons than electrons.
An ion can have a positive charge (cation) if it has lost electrons, or a negative charge (anion) if it has gained electrons. The charge of an ion is determined by the number of electrons it has gained or lost during the process of ionization.
A positive oxidation number represents the charge an atom would have if electrons were transferred to the more electronegative atom in a compound. It signifies that the atom is losing electrons and becoming oxidized in a chemical reaction.
An element you have a +2 charge It is had lost electrons. It would have to lose the same number of electrons that its positive charge is. So it would have lost 2 electrons.
