An atom which has lost an electrons forms a positive ion which is called cation.
ANSWER: ADDENDUM A nucleus does not loose an electrons it just has temporarily misplaced an electrons by am external force. That electron will be practically replace immediately by an electron from the next nucleus that is how electron current is generated and sustained
it is called ion or cation to be more specific.
When an atom loses electrons, leaving it with more protons than electrons, it becomes a cation, which has a positive charge. An anion has more electrons than protons.
An atom that loses one or more electrons is an ion, specifically a cation.
Ion
ion
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.
If an atom gains an electron, it becomes an anion, which is negative. Anions are larger than the original atom because of the added electrons. N + electron(-) --> N(-) If an atom loses an electron, it becomes a cation and positively charged. Cations are smaller than the original atom because of the lost electrons. N(2+) = cation
When an atom gains or loses one or more electrons, it forms an ion. If it loses electrons, it becomes a positively charged ion called a cation. If it gains electrons, it becomes a negatively charged ion called an anion.
it gains or acquires a charge either positive or negative so when it gains energy, it aquires a negative charge then when it loses energy, it aquires a positive charge
An atom becomes more positive when it loses an electron because electrons carry a negative charge. When an atom gains an electron, the atom becomes more negative.
A cation.
An atom that loses one or more electrons becomes positively charged, because the number of protons (+) in the nucleus will outnumber the electrons (-).
ion
An atom that loses one or more electrons becomes a positively charged ion.
When an atom loses electrons it becomes ionized and more positive a charge. Losing an electron can cause this atom to react with other atoms.
An atom has three charges: protons which are +, electrons which are - and neutrons which have neither. They balance each other out. If electrons are lost, the atom now has more protons and the atom becomes positive.
When a neutral atom loses one or more electrons, the atom becomes a positive ion.
An atom that loses one or more electrons is an ion, specifically a cation.
If an atom loses an electron (electrons are negative), the atom becomes 'less negative' which means 'more positive'. Atoms are normally neutral (no charge), so losing one electron gives it a positive charge. When an atom has a charge it is called an ION. So the atom becomes a Positively Charged Ion.
Atoms that gain or lose electrons are called ions. If it gains one or more electrons it becomes negative it is called an anion. If it loses one or more electrons and becomes positive it is called a cation.
An atom becomes a positively charged ion when it loses one or more electrons.
