Why does an atom that has lost an electron have a positive charge?
Wiki User
∙ 12y ago
Every atom has a positively charged nucleus containing protons, each with a 1+ charge. Electrons, each with a -1 charge surround the nucleus. In a neutral atom the number of electrons is equal to the number of protons, so there is no net charge. If an atom loses electrons it will have more protons than electrons resulting in an overall positive charge.
For example, a neutral magnesium atom has 12 protons and 12 electrons, resulting in an ion with 12 protons and 10 electrons. Since there are two more protons than electrons in this ion, the overall charge is 2+

∙ 9y agoWhen an atom loses a negative charge it is left with a positive charge because atoms tend to be balanced. The positively charged atom won't remain so for long because it will be attracted to negatively charged atoms.

∙ 14y agoAn atom is made up of protons and neutrons with electrons that orbit the nucleus. Electrons have a negative charge, protons a positive charge, and neutrons no charge at all. When an electron leaves an atom's orbital, it removes a negative charge, leaving more protons than electrons, resulting in a positive charge (assuming the number of protons and electrons were equal).

An atom that has lost or gained an electron resulting in a net charge?
positive
The removal of an electron results to what charge?
+1. Because an atom normally has an equal number of protons and electrons, it is neutral. By removing a negative (the electron), the atom is then positive. The more electrons you remove, the more positive the atom becomes. Then, it is called an ion, such as Cu is copper, but Cu2+ is a copper(II) ion; it is a copper atom that has lost two electrons.
What kind of charge would a sodium atom have if it lost one electron?
Sodium become a cation (positive charge) - Na+.
A molecule is an atom that has gained or lost an electron?
The answer is simply an "ion." The atom itself cannot be named until it has gained or lost an electron, in which it has lost an electron to become more positive, it would become a cation. If the ion had gained an electron to become more negatively charged, it is then named an anion.
What are atoms that have an electrical charge due to gain or loss of electrons?
A cation for an atom that has lost an electron and is now positive and an anion for an atom that gained an electron and is now negative.The general term for an atom with a different number of electrons than protons is an ion.
An atom that has lost or gained an electron resulting in a net charge?
positive
What are differences between atom and ion?
An atom has no charge. An ion is an atom that has either gained or lost an electron giving it a charge. An atom that has gained an electron is called an anion and is negative, while an atom that lost an electron is called a cation and is positive.
What difference between atom and ion?
An atom has no charge. An ion is an atom that has either gained or lost an electron giving it a charge. An atom that has gained an electron is called an anion and is negative, while an atom that lost an electron is called a cation and is positive.
What can you infer about ion that has an positive charge?
This ion is derived from atom who lost one electron.
The removal of an electron results to what charge?
+1. Because an atom normally has an equal number of protons and electrons, it is neutral. By removing a negative (the electron), the atom is then positive. The more electrons you remove, the more positive the atom becomes. Then, it is called an ion, such as Cu is copper, but Cu2+ is a copper(II) ion; it is a copper atom that has lost two electrons.
When a atom has a positive or negative charge beause it lost or gained an electron is a?
An atom has a postitive charge when it loses an electron and a negative when it gains one. It then becomes an ion through this process.
What kind of charge would a sodium atom have if it lost one electron?
Sodium become a cation (positive charge) - Na+.
What is an atom that has given up or gained electrons?
Atoms that have lost or gained one or more electrons are called ions.An atom that has gained and electron is an anion; and atom that has lost an electron is a cation. Gaining an electron means the anion has a negative charge; losing one or more electrons means the atom has a positive charge.
When electrons are lost from an atom what type of ions are formed?
Losing an electron makes an atom take on a positive charge, therefore it becomes a cation, or a positive ion.
What is a neutral atom that gains or loses electrons?
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.
A molecule is an atom that has gained or lost an electron?
The answer is simply an "ion." The atom itself cannot be named until it has gained or lost an electron, in which it has lost an electron to become more positive, it would become a cation. If the ion had gained an electron to become more negatively charged, it is then named an anion.
If an atom gives up an electron does it it have a positive charge?
Yes. It becomes a cation (a positive ion). Yes. Each positively charged proton in the nucleus must be cancelled out by a negatively charged electron, or else any noncancelled proton's positive charge will give its atom a positive charge. Likewise the atom that gains the lost electron will have more negatives than positives and will gain a negative charge.
