What atomic number is F?

What atomic number is F?

Fluorine (F) is the first element in the Halogen group (group 17) in the periodic table. Its atomic number is 9 and its atomic weight is 19, and it’s a gas at room temperature.

What is the electron number of F?

9 electrons
Fluorine is the ninth element with a total of 9 electrons. In writing the electron configuration for fluorine the first two electrons will go in the 1s orbital. Since 1s can only hold two electrons the next 2 electrons for F go in the 2s orbital. The remaining five electrons will go in the 2p orbital.

What are two properties of fluorine?

Fluorine has two solid forms, α- and β-fluorine. The latter crystallizes at −220 °C (−364 °F) and is transparent and soft, with the same disordered cubic structure of freshly crystallized solid oxygen, unlike the orthorhombic systems of other solid halogens.

How many electrons does fluorine have?

Fluorine atoms have nine electrons, one fewer than neon, and electron configuration 1s 22s 22p 5: two electrons in a filled inner shell and seven in an outer shell requiring one more to be filled.

What is the name of fluorine ion?

Fluoride is the negative ion of the element fluorine. The symbol for the element fluorine is F. Fluoride often is written as F -, which stands for the anion of fluorine that has a -1 electrical charge.

What is the atomic number of fluorine?

The atomic number of the element Fluorine is 9
