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
An atom becomes charged when it either gains or loses one or more electrons. If an atom gains electrons, it becomes negatively charged (anion); if it loses electrons, it becomes positively charged (cation). This process is known as ionization.
When an atom gains electrons, it becomes negatively charged because it now has more electrons than protons. When an atom loses electrons, it becomes positively charged because it now has more protons than electrons.
An atom becomes an ion by gaining or losing electrons. When an atom loses electrons, it becomes a positively charged ion (cation) as it has more protons than electrons. On the other hand, when an atom gains electrons, it becomes a negatively charged ion (anion) as it has more electrons than protons.
A positive ion. Originally atoms have a neutral charge with equal amount of electrons and protons. If atom loses electrons, it still has the same amount of protons so it becomes a positive ion
A neutral atom that subsequently gains or loses one [or more] electrons is called an ion. If it gains an electron [or electrons] it will have a negative charge. If it loses an electron [or electrons] it will have a positive charge.
An atom becomes charged when it either gains or loses one or more electrons. If an atom gains electrons, it becomes negatively charged (anion); if it loses electrons, it becomes positively charged (cation). This process is known as ionization.
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 (-).
When an atom loses an electron to another atom, it becomes positively charged because it now has more protons than electrons. The atom that gains the electron becomes negatively charged because it now has more electrons than protons. This transfer of electrons creates ions that may attract or repel each other depending on their charges.
When an atom gains electrons, it becomes negatively charged because it now has more electrons than protons. When an atom loses electrons, it becomes positively charged because it now has more protons than electrons.
An atom is electrically neutral; it has the same number of positively charged protons as it has negatively charged electrons. If an atom either gains or loses one or more electrons, then it will have an electric charge, and will be an 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.
An atom becomes a positive ion by losing electrons, resulting in more protons than electrons. This creates a net positive charge. An atom becomes a negative ion by gaining electrons, leading to more electrons than protons. This creates a net negative charge.
If it loses an electron (negative charge) it becomes positive.
An atom becomes an ion by gaining or losing electrons. When an atom loses electrons, it becomes a positively charged ion (cation) as it has more protons than electrons. On the other hand, when an atom gains electrons, it becomes a negatively charged ion (anion) as it has more electrons than protons.
