What is the atomic number of an element with 9 electrons?

Atom of an element has 9 electrons 9 protons and 10 neutrons what is atomic no.? The atomic number is 9. The atomic number of an element is the number of protons in one atom of that element.

Which of the following elements has 9 protons?

The element that has 9 protons is fluorine. Its atomic number is 9, indicating that the element has 9 protons in the nuclei of its atoms. If there are 10 electrons, then the fluorine atom has gained an electron and is now a negatively charged anion with a charge of 1-.

How many protons and electrons does fluorine have?

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.

How do you find the atomic number of an element?

The atomic number of an element is the number of protons in one atom of that element. Thus, if an atom of an element has nine protons, then its atomic number is also nine.

How to find the number of neutrons?

1 Answer. The number of neutrons is obtain through the difference of the mass number and the number of electrons.

How many electrons does fluorine have?

Since the number of electrons equal the number of protons, Fluorine has 9 electrons as well.

What is the atom number 9?

If we look on the periodic table, atom number 9 is called fluorine.

What is the atomic number of an element?

Explanation: The atomic number of an element is the number of protons in one atom of that element. Thus, if an atom of an element has nine protons, then its atomic number is also nine.
