What has 9 protons 9 neutrons and 9 electrons?

The atomic number is also called the proton number of the element. Since this atom has 9 protons, then its atomic number will be 9 . If we look on the periodic table, atom number 9 is called fluorine.

How many electrons if there are 9 protons?

9 electrons
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. Meanwhile, it’s mass number of 19, minus 10 neutrons, gives you 9 protons or electrons. Hence, the atom would be Fluorine.

### How many protons neutrons and electrons does be 9 have?

How many protons neutrons and electrons are there in a neutral atom of beryllium-9? From the periodic table, beryllium has an atomic number of 4 and a mass of almost 9 amu. Therefore, a neutral beryllium atom has 4 protons, 4 electrons, and 5 neutrons (# neutrons = mass # – # protons).

What atom has 9 electrons and 9 protons?

Fluorine atom has 9 electrons and 9 protons.

What element in the periodic table that has 9 electrons?

Fluorine is a chemical element with the symbol F and atomic number 9.

#### Which element has 9 electrons 9 protons?

element fluorine
The element fluorine has 9 protons and 9 electrons.

What ion has 9 protons 9 neutrons and 10 electrons?

A flourine ion contains 9 protons, 9 neutrons, and 10 electrons.

How do you find the number of protons electrons and neutrons?

The number of protons in the nucleus of the atom is equal to the atomic number (Z). The number of electrons in a neutral atom is equal to the number of protons. The mass number of the atom (M) is equal to the sum of the number of protons and neutrons in the nucleus.

## What has 9 protons 9 electrons and 10 neutrons?

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. Meanwhile, it’s mass number of 19, minus 10 neutrons, gives you 9 protons or electrons. Hence, the atom would be Fluorine.

What is the name of the element that has 9 protons?

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.

How do you calculate the number of protons in an atom?

Locate the element’s atomic number. The atomic number is located above the element symbol, in the upper left-hand corner of the square. The atomic number will tell you how many protons make up a single atom of an element. For example, boron (B) has an atomic number of 5, therefore it has 5 protons.

### How many protons neutrons and electrons are in each element?

7 protons, 7 electrons, 7 neutrons Oxygen, O 8 protons, 8 electrons, 8 neutrons Fluorine, F 9 protons, 9 electrons, 10 neutrons Neon, Ne 10 protons, 10 electrons, 10 neutrons Sodium, Na 11 protons, 11 electrons, 12 neutrons Magnesium, Mg 12 protons, 12 electrons, 12 neutrons Aluminium, Al 13 protons, 13 electrons, 14 neutrons Silicon, Si

What is the number of neutrons in an element?

The atomic number of the element equals the number of protons. Calculating the number of neutrons then becomes atomic mass of the isotope minus the atomic number of the element equals the number of neutrons. For uranium-235, atomic number 92, the number of neutrons is 235-92=143, or 143 neutrons.

How do protons neutrons and electrons compare?

When you compare the masses of electrons, protons, and neutrons, what you find is that electrons have an extremely small mass, compared to either protons or neutrons. On the other hand, the masses of protons and neutrons are fairly similar, although technically, the mass of a neutron is slightly larger than the mass of a proton.
