How many neutrons does fluorine 19 have?
10 neutrons
This isotope of fluorine has 9 protons, 9 electrons and 10 neutrons.
What is the shorthand for an element?
Shorthand electron configuration of an element starts with the symbol of the noble gas in the previous period, followed by the rest of the electron configuration for the element in question.
How many electrons does 19 have?
19 protons, 20 neutrons and 18 electrons.
What is fluorine 19 charge?
It has an extra electron, and so it has a negative charge.
What is fluorine-18 used for?
Fluorine-18 fluorodeoxyglucose (F-18 FDG) positron emission tomography (PET), used most commonly for tumor, cardiac, and brain imaging, is increasingly being used to detect infection. Increased FDG uptake occurs with inflammation and infection as a result of activation of granulocytes and macrophages.

What is shorthand form?
Shorthand is an abbreviated symbolic writing method that increases speed and brevity of writing as compared to longhand, a more common method of writing a language. The process of writing in shorthand is called stenography, from the Greek stenos (narrow) and graphein (to write). Many forms of shorthand exist.
What does shorthand notation look like?
Shorthand notation uses the noble gas of the previous line. This is due to the fact that all the orbitals up to that noble gas are completely filled. Then, you start filling in the orbitals for the element for the row that it is in. I will use two examples—magnesium (Mg) and bismuth (Bi)—to show the shorthand form.
How many valence electrons does fluorine-19 have?
It is the most electronegative element, given that it is the top element in the Halogen Group, and therefore is very reactive. It is a nonmetal, and is one of the few elements that can form diatomic molecules (F2). It has 5 valence electrons in the 2p level. Its electron configuration is 1s22s22p5.

How many electrons does fluorine have on the periodic table?
Fluorine is a 9. chemical element in the periodic table of elements. It has 9 protons and 9 electrons in the atomic structure. The chemical symbol for Fluorine is F.
What are the signs and symptoms of fluorine exposure?
First Aid. Warning: Fluorine is a corrosive gas and may be converted to hydrofluoric acid in the lungs and on other moist tissue. Signs and Symptoms of Fluorine Exposure: Signs and symptoms of acute exposure to fluorine include coughing, choking, and chills. Eye, nose, skin, and respiratory irritation may occur.
What are hydrogen fluoride and hydrofluoric acid used for?
Fluorine and hydrogen fluoride are used to make certain chemical compounds. Hydrofluoric acid is used for etching glass. Other fluoride compounds are used in making steel, chemicals, ceramics, lubricants, dyes, plastics, and pesticides.
