Does fluorine have a mass number of 19?
A neutral atom of fluorine has a mass number of 19 and an atomic number of 9.
What is the atomic number of fluorine-19?
9
Fluorine-19 has an atomic number of 9. The atomic number is equal to the number of protons in an element and can be identified on the periodic table….
What is the mass number of 19 9F?
18.9984 amu
Use 18.9984 amu as the actual mass of 19 9F.
What is fluorine-19 charge?
It has an extra electron, and so it has a negative charge.
What does the number 19 represent in 19 9 F?
fluorine
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.
What is the difference between fluorine-18 and fluorine-19?
Only fluorine-19 is stable and naturally occurring; therefore, fluorine is a monoisotopic and mononuclidic element, and only artificially produced fluorine isotopes have mass numbers other than 19. The longest-lived radioisotope is 18F; it has a half-life of 109.739 minutes.
What is the difference between fluorine 18 and fluorine 19?
What element has a mass of 19?
Potassium
