What is the charge of fluorine 19?
What is the charge of fluorine 19?
A fluorine atom has nine protons and nine electrons, so it is electrically neutral. If a fluorine atom gains an electron, it becomes a fluoride ion with an electric charge of -1.
What is the mass number of fluorine 19?
Fluorine
| Isotope | Atomic mass (Da) | Isotopic abundance (amount fraction) |
|---|---|---|
| 19F | 163(6) | 1 |
How many protons neutrons and electrons are in fluorine 20?
| Name | Fluorine |
|---|---|
| Atomic Mass | 18.998 atomic mass units |
| Number of Protons | 9 |
| Number of Neutrons | 10 |

How many protons neutrons and electrons are in fluorine 18?
F- has 9 protons, 9 neutrons, 10 electrons.
Why is fluorine-18 used?
Because of its short half-life and positron emission, 18F is widely used in molecular imaging of biological and biochemical processes, including early detection of many diseases and assessment of treatment response by positron emission tomography (PET) [24-34].
Why is fluorine-18 unstable?
Fluorine-18 Of the unstable nuclides of fluorine, 18F has the longest half-life, 109.739 minutes. It has two decay modes, of which the main one is positron emission. For this reason 18F is a commercially important source of positrons. Like all positron-emitting radioisotopes, 18F also may decay by electron capture.
What happens when fluorine-18 enters the body?
For example, fluorine-18 labelled fluorodeoxyglucose, also called FDG, is a radioactive version of the sugar glucose (the isotope of fluorine is tagged to glucose, which has a half-life of about 112 minutes). Once injected into the body, it will go to places where glucose is used for energy.
How is fluorine-18 disposed?
Fludeoxyglucose F 18 that is not involved in glucose metabolism in any tissue is then excreted in the urine. Fludeoxyglucose F 18 is cleared from most tissues within 24 hours and can be eliminated from the body unchanged in the urine.
How is chlorine 36 used?
Chlorine-36 has been widely used for dating old groundwater. The 36Cl used for this purpose is produced in the atmosphere by the interaction of cosmic rays with argon atoms. The 36Cl then mixes with ordinary atmospheric chloride (mostly derived from the ocean).
Is chlorine 37 radioactive?
There are only two stable isotopes: 35Cl and 37Cl with respective proportions of 75.76% and 24.24% (Berglund and Wieser 2011). The longest-lived radioactive isotope is 36Cl (half-life of 301,000 years); all other isotopes having half-lives of less than 1 h.
How many protons does chlorine 37 have?
17 17
How many electrons are in CI?
17 electrons
What is the electron configuration of Cl 1?
The electron configuration for Cl-1 is [Ne] 3s2 3p6.
