Name: Fluorine Symbol: F Atomic Number: 9 Atomic Mass: 18.998404 amu Melting Point:-219.62 °C (53.530006 K, -363.31598 °F) Boiling Point:-188.14 °C (85.01 K, -306.652 °F) Number of Protons/Electrons: 9 Number of Neutrons: 10 Classification: Halogen Crystal Structure: Cubic Density @ 293 K: 1.696 g/cm 3 Color: Greenish Atomic Structure.
List the number of protons, electrons, and neutrons in each of the following atoms/ions. For each atom/ion, write a brief (1 – 2 sentences) description of how you determined the number of protons, electrons, and neutrons. A) Calcium cation with a full valence shell and 40 neutrons b) The most common fluorine isotope on Earth (no charge).
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.

How many unpaired electrons in a ground state fluorine atom?

Step 4: Find number of bonds by dividing the number of bonding electrons by 2 (because each bond is made of 2 e-) 8e-/2 = 4 bonds. Step 5: The rest are nonbonding pairs. Subtract bonding electrons (step 3) from valence electrons (step 1). 32-8= 24e-= 12 lone pairs. Use information from step 4 and 5 to draw the CF 4 lewis structure.

1 Answer

Fluorine has one unpaired electron in the ground state.

Explanation:

Fluorine is in the #2nd# Energy Level (row) of the Periodic Table and in the #5th# column of the #p# block making the electron configuration#1s^2 2s^2 2p^5#

The outermost shell of the atom would have #7# electrons.

The Bohr Model would have #2# electrons in the fist orbital and #7# electrons in the second orbit level.
