Typically, a negative ion is formed by gaining electrons. This is because electrons hvae a negative charge. An example of a case where a positive ion can be formed by gaining an electron is when an ion with a charge of +2 can gain 1 electron and become +1. Technically in this case, a positive ion was formed when an electron was gained but the trend was that the ion became more negative not positive.

What atoms can form an ion?
an atom which readily losses or gains electrons to attain stability forms an ion.
What must happen in order for an ion to form?
An ion forms when an atom gains or loses electrons to have a stable electron configuration. When an atom gains electrons, it forms a negatively charged ion (anion), and when it loses electrons, it forms a positively charged ion (cation).
When an atom gains an electron what charge does it have?
An atom that gains three electrons will become an ion with a 3- charge.
When the number of electrons in an atom changes what is the new atom called?
When an atom loses or gains electrons, it becomes an ion.
What is the energy change that occurs when an atom gains electrons called?
The energy change that occurs when an atom gains electrons is called the
What do you call an atom that gains or loses electrons?
An atom that gains or loses electrons is called an ion. If it gains electrons, it results in a negative ion called an anion. If it loses electrons, it results in a positive ion called a cation.
What atoms can form an ion?
an atom which readily losses or gains electrons to attain stability forms an ion.
How many electrons does a sulfur atom lose to form an ion?
they both gain 2 electrons becoming the anions Oxide and Sulfide, O2- and S2-
An atom that loses or gains electrons becomes a?
An atom that loses electrons becomes a positively charged ion called a cation. An atom that gains electrons becomes a negatively charged ion called an anion.
When a atom loses or gains electrons it becomes an?
When an atom loses electrons, it becomes a positively charged ion called a cation. When an atom gains electrons, it becomes a negatively charged ion called an anion.
What happen when an atom forms 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.
What must happen in order for an ion to form?
An ion forms when an atom gains or loses electrons to have a stable electron configuration. When an atom gains electrons, it forms a negatively charged ion (anion), and when it loses electrons, it forms a positively charged ion (cation).
Are ion stable?
because they form in compund where one atom loses electrons and other gains.
What does an atom become when it loses or gains electrons?
it becomes an 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.
What does an atom become if it gains or loses electrons?
If an atom gains or loses electrons, it becomes an ion. If it gains electrons, it becomes a negatively charged ion called an anion. If it loses electrons, it becomes a positively charged ion called a cation.
When an atom gains electrons what does it become?
It becomes an ion.
