Cation
A way to remember is that you know electrons are negatively charged, and if an atom loses an electron it becomes positively charged, pos=paws cats have paws positive ions are cations. Anions sounds like anti-ions anti is negative anions are negative.
A cation i.e positive ion is formed when atoms loses an electron. As no. of proton and electron are equal in neutral atom. As electron is removed the proton becomes greater in no. So a positive ion is formed.
Electrons are negatively charged, so if a neutral atom loses one, the atom becomes positively charged. Positively charged atoms are called cations (if it gains an electron, it becomes more negatively charged and becomes and anion).
When an atom loses one or more electrons, it becomes a positively charged ion, called a cation. In a neutral atom, the numbers of protons and electrons are equal. However, when an atom loses electrons, the number of protons remains the same. This results in more positively charged protons than negatively charged electrons, so the overall charge on the ion is positive.
For example, an aluminum atom lose three electrons when forming its cation. A neutral aluminum atom has 13 protons and 13 electrons. When the aluminum atom loses 3 electrons, the resulting aluminum ion has 10 electrons and 13 protons. Since there are now 3 more protons than electrons, it develops an ion with a 3+ charge.
Losing an ion creates a positive charge. This forms a positive ion.
If an atom loses an electron it loses a negative charge. This will mean the atom now has a positive charge overall because the electron is no longer there to cancel it out.
A positive ion is formed when atoms lose electrons. When a cell gains an electron it becomes negative
When an atom loses an electron it becomes a positive ion or cation, because electrons are negatively charged.
A positive ion, because it loses negative charges.
A cation - a positive ion
When an atom loses or gains an electron, it forms an ion. Similarly if a molecule also lose or gain an electron it forms a molecular ion ,e.g CH4+ CO+ etc.

An atom that has lost or gained an electron or electrons is called an ion. When an atom loses an electron, it forms a positive ion because the protons then outnumber the electrons. When an atom gains an electron, it forms a negative ion because the electrons now outnumber the protons. A positive ion is called a cation (pronounced "cat-ion" not "ca-shun.") A negative ion is called an anion (pronounced "an-ion" not "an-yun.")
That would be an ion.
For an atom to form an ion, it has to either gain or lose one or more electrons. Usually this happens during a chemical reaction, when an element gains or loses electrons to achieve noble gas configuration.
Losing an ion creates a positive charge. This forms a positive ion.
Atoms NEVER lose protons, just electrons.
Type your answer here... when helium atom removes a electron it forms a helium+ ion.(He+)
positive ion forms when any electron removes from an atom and an anion called negative ion forms when an atom accepts an additional electron
The ion has a smaller diameter.
The lithium atom lose an electron.
it is an ion
A positive ion, or cation forms.
No, typically hydrogen forms a positive ion.
A positive ion is formed when an atom loses one or more then electrons.
The atom had either lost or gained one or more electrons forming and ion. Thus the ion has an overall electric charge.
A charged particle that forms when an atom transfers electrons is an ion. An atom that loses an electron forms a positively charged ion called a cation; an atom that gains an electron forms a negatively charged ion called an anion.
