Will fluorine gain or lose electrons?
When forming ions, elements typically gain or lose the minimum number of electrons necessary to achieve a full octet. For example, fluorine has seven valence electrons, so it is most likely to gain one electron to form an ion with a 1- charge.
What happens when an electron is gained?
If an atom or molecule gains an electron, it becomes negatively charged (an anion), and if it loses an electron, it becomes positively charged (a cation). Energy may be lost or gained in the formation of an ion.
What would happen if fluorine loses an electron?
It can lose one of its electrons, making it an ion. It now has more positive protons than electrons so it has an overall positive charge. Therefore it is a positive ion. A fluorine atom will tend to gain, rather than lose, an electron.
What happens to fluorine when it gains a proton?
An electrically neutral fluorine atom contains nine protons and nine electrons. When this atom gains an elec- tron, the result is a negative ion.
Why does the fluorine atom tend to gain only one electron?
Answer and Explanation: The fluorine atom tend to gain only one electron because the outer shell needs to be stabilized. Fluorine has 7 electrons in its outer shell, and it needs 8 electrons to be considered full. Therefore, gaining one electron will allow the atom to be full from 7 to 8.
When an atom loses or gains electrons what does it become?
If an atom loses or gains electrons, it will become a positively or negatively charged particle, called an ion. The loss of one or more electrons results in more protons than electrons and an overall positively charged ion, called a cation.
How does fluorine become an ion?
Fluorine, F It has seven electrons in its outer shell. It gains an electron from another atom in reactions, forming a fluoride ion, F -. Note that the atom is called fluorine, but the ion is called fluoride.
How do you know if an ion loses or gains an electron?
When an ionic compound forms, the more electronegative element will gain electrons and the less electronegative element will lose electrons.
Is fluorine positive or negative?
It has an extra electron, and so it has a negative charge. An atom with one or more extra charges is called an “ion”. A negatively charged ion like fluorine is called an “anion”.
How many electrons are in F -?
As a neutral atom, the number of protons it has must be equal to the number of electrons, as they are particles of opposite charge and a neutral atom has a total charge of zero. Therefore, F atom has 9 electrons total and F− has 10 electrons total.

When fluorine becomes an ion What will its charge be and what noble gas will it have the same electron configuration as?
The electron configuration of a F− ion is 1s22s22p6 . This is the same electron configuration as neon, which has atomic number 10, so it has 10 protons and 10 electrons in its neutral atoms.
What happens to the atomic radius when an electron is gained?
The gain of an electron adds more electrons to the outermost shell which increases the radius because there are now more electrons further away from the nucleus and there are more electrons to pull towards the nucleus so the pull becomes slightly weaker than of the neutral atom and causes an increase in atomic radius.
When electrons are gained a ion is formed?
Ions are formed when atoms lose or gain electrons in order to fulfill the octet rule and have full outer valence electron shells. When they lose electrons, they become positively charged and are named cations. When they gain electrons, they are negatively charged and are named anions.
What is being formed when an atom gains an electron?
When an atom loses or gains an electron, ions are formed. If an atom loses electron it forms positive charge and if gains electron it forms negative charge. An atom which carries charge on it is known as ion.
How do electrons gain energy?
The electron can gain the energy it needs by absorbing light. If the electron jumps from the second energy level down to the first energy level, it must give off some energy by emitting light. The atom absorbs or emits light in discrete packets called photons, and each photon has a definite energy.
