Which element has 9 electrons 9 protons?

By looking at the periodic table, you will see that Fluorine has 9 protons. Since the number of electrons equal the number of protons, Fluorine has 9 electrons as well.

What atom has 9 protons in its nucleus?

fluorine atom
For example, a fluorine atom has 9 protons and 10 neutrons. Its atomic number is 9, while its atomic mass is 19 atomic mass units. So we can say that its atomic weight is 19, or its mass number is 19.

What are 3 uses for fluorine?

Fluorine is important in creating nuclear material for nuclear power plants and insulating electrical towers. It also is used to etch glass in the form of hydrogen fluoride. Fluorine is used to make plastics, such as Teflon, and is also important in dental health.
