# Fluorine Protons Neutrons Electrons

Posted on  by admin
If atoms gain electrons, they become negative ions, or anions. Consider the example of fluorine (see Figure below). A fluorine atom has nine protons and nine electrons, so it is electrically neutral. If a fluorine atom gains an electron, it becomes a fluoride ion with an electric charge of -1.

1. The nucleus of fluorine has 9 protons. Surrounding the nucleus of fluorine is 9 electrons. The electrons arrange themselves in 3 orbits: In the first orbit, there are 2 electrons. In the second orbit, there are 7 electrons. In the third orbit, there are no electron. Bohr deduced that: electrons inside an atom possess different energies.
2. Therefore it has 9 protons in the nucleus and 9 electrons around the nucleus. The number of neutrons in the nucleus of fluorine-17 is 17-9 = 8. The electrons are often shown of as arranged in orbits: 2 in the inner orbit and 7 in the outer orbit for fluorine. Take 9 cherries (=9 protons) and 8 grapes (=8 neutrons) and stick them together.

Name: Fluorine Symbol: F Atomic Number: 9 Atomic Mass: 18.998404 amu Number of Protons/Electrons: 9 Number of Neutrons: 10 Date of Discovery: 1886 Discoverer: Joseph Henri Moissan.

Thereof, does fluorine gain or lose electrons?

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. A fluorine atom will tend to gain, rather than lose, an electron. By gaining a negative electron, it has an overall negative charge.

what happens when an atom gains an electron? However, if something happens to make an atom lose or gain an electron then the atom will no longer be neutral. An atom that gains or loses an electron becomes an ion. If it gains a negative electron, it becomes a negative ion. If it loses an electron it becomes a positive ion (see page 10 for more on ions).

Hereof, how many electrons does fluorine gain or lose?

Example 1: A fluorine atom can get a full valence shell by either gaining one more electron, or by losing seven electrons. The former requires the transfer of less electrons, so the fluorine atom will try to gain one electron first. Therefore, F− ions are more common than F7+ ions.

What happens when fluorine atoms react?

Fluorine is in Group 7. It has seven electrons in its outer shell. It gains an electron from another atom in reactions, forming a fluoride ion, F-. A fluoride ion has the same electronic structure as a neon atom (Ne).
