Because the atom is neutral, there are also 8 electrons . Number of nucleons (which is the larger of the two numbers because it counts all nucleons, not just protons): 16. This is the total number of protons and neutrons. Subtract the number of protons (8) and you get the number of neutrons, which is also 8.
How do you find the number of electrons in a neutral atom?
The number of electrons on a neutral atom is equal to the number of protons in the nucleus of the atom
How many electrons are in a neutral atom of F?
So... for the element of FLUORINE, you already know that the atomic number tells you the number of electrons. That means there are 9 electrons in a fluorine atom
How many neutrons are in a neutral atom?
An atomic number of 11 means this atom will have 11 protons. A mass number of 23 means 23 – 11 this atom will have 12 neutrons . Since this atom is neutral the positive protons must be equal to the negative electrons.
How many electrons are there in the neutral atom 19 9 F?
There are 9 electrons .
What are the 9 electrons of fluorine?
| Name Fluorine | Atomic Mass 18.998 atomic mass units | Number of Protons 9 | Number of Neutrons 10 | Number of Electrons 9 |

How do I know if an atom is neutral?
When an atom has an equal number of electrons and protons , it has an equal number of negative electric charges (the electrons) and positive electric charges (the protons). The total electric charge of the atom is therefore zero and the atom is said to be neutral.
What is a neutral atom example?
Atoms are neutral; they contain the same number of protons as electrons. ... A neutral sodium atom , for example, contains 11 protons and 11 electrons. By removing an electron from this atom we get a positively charged Na + ion that has a net charge of +1. Atoms that gain extra electrons become negatively charged.
Are all atoms neutral?
Every atom has no overall charge (neutral) . This is because they contain equal numbers of positive protons and negative electrons. These opposite charges cancel each other out making the atom neutral.
What is the nuclear charge of 19 9 F?
Can you figure out the answers by yourself now? Nuclear charge +9 : 9 protons, fluorine or F. # of neutrons = 19 – 9 = 10. Neutral atom, so (# of electrons) = (# of protons) = 9.
What is the atomic mass of F 19?
| ChEBI Name fluorine-19 atom | Definition The stable isotope of fluorine with relative atomic mass 18.998403 and nuclear spin 1 / 2 . | Stars This entity has been manually annotated by the ChEBI Team. | Supplier Information | Download Molfile XML SDF |

What does the number 19 represent in 19 9 F?
In general atoms are electrically neutral. Therefore the number of protons must equal the number of electrons. In some atoms the number of protons is also equal to the number of neutrons. The atomic number of fluorine is 9 and its mass number is 19.
Is the number of nucleons equal to the number of electrons?
The number of nucleons present in the nucleus is equal to the number of electrons present outside the nucleus .
Can oxygen have 10 electrons?
Oxygen has atomic number eight. This means that the nuclei of all oxygen atoms have eight protons. A neutral oxygen atom will also have eight electrons. In an oxygen ion with a 2− charge, the number of protons is still 8, but the number of electrons is 10 .
