What has a mass number of 19?
The chemical element fluorine is a gas that has a mass number of 19.
How many neutrons are in a fluorine atom with a mass number of 19?
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. So we can say that its atomic weight is 19, or its mass number is 19.
What is the mass in grams of a single fluorine-19 atom?
Determine the mass of 1 F-atom in gramm (F-19). Gram-atomic mass of fluroine=19g. =3.1550×10-23g.
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.
Which statement about an atom of fluorine-19 9f is correct?
The correct statement about an atom of fluorine, 19 F 9, is that it contains a total of 28 protons, electrons and neutrons. In 19 F 9, F stands for fluorine which is a chemical element and 9 stands for atomic number i.e its atomic number is 9.
How many electrons does 19 have?
19 protons, 20 neutrons and 18 electrons.
What is the atomic number of an atom with a mass of 19 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 isotope has 19 protons and 20 neutrons?
The element of potassium has the symbol K. The nucleus of an atom of potassium contains 19 protons and 20 neutrons.
What is fluorine formula?
Fluorine is the chemical element in the periodic table that has the symbol F and atomic number 9. ... In its pure form, it is a poisonous, pale, yellow-green gas, with chemical formula F2. Like other halogens, molecular fluorine is highly dangerous; it causes severe chemical burns on contact with skin.
What element has an electron of 19?
For example, for Potassium (K) (atomic #19), the preceding noble gas is Argon (Ar) (atomic #18). Thus, the configuration shown for Potassium is [Ar]4s1 (see Table below). Potassium (K) atom has 19 electrons.
What isotope has 19 protons and 22 neutrons?
Potassium-41 - It has 19 protons and atomic mass is 41. Hence, number of neutrons is 41 - 19 which is 22.
What is the mass number of an element with 19 protons 19 electrons and 21 neutrons?
The element potassium's atomic number is 19. Its relative atomic mass is 39.098.
