Potassium is a metal element. Atomic Mass of it is 30.
Fluorine is a non metal element. Atomic mass of it is 19.
To find the number of protons, you need to subtract the number of neutrons from the mass number. In this case, the atom has a mass number of 19 and 10 neutrons, which means the number of protons is 19 - 10 = 9 protons.
The atomic number is 19 and the mass number of its most abundant isotope K-39 is 39 (19 protons + 20 neutrons) while the mass of that isotope is 38.96371 a.m.u.The relative atomic mass of the element potassium, K, is 39.10 g/mole.
The atomic number is the number of protons: 19.number of neutrons = mass number - atomic number = 21.The number of electrons is normally the same as the number of protons: 19
This gas is likely to be fluorine (F), which has a mass number of 19. Fluorine is a highly reactive, pale yellow gas that is part of the halogen group on the periodic table. It is commonly found in compounds rather than in its pure elemental form due to its high reactivity.
K, or potassium, has a mass number of 19. Fluorine is a non metal element. Mass number of it is 19. No, mass number for potassium is not 19. That is the atomic number.
Fluorine is a non metal element. Mass number of it is 19.
Fluorine is a gas with a mass number 19.
The mass number of fluorine-19 is 18.998404 amu.
Fluorine is a non metal element. Atomic mass number of it is 19.
To find the atomic mass, subtract the atomic number (protons) from the mass number (protons + neutrons). Atomic mass = Mass number - Atomic number Atomic mass = 19 - 9 Atomic mass = 10amu So, an atom with an atomic number of 9 and a mass number of 19 would have an atomic mass of 10 atomic mass units (amu).
Answer is in the question itself. 19. Because atomic mass is nearly equal to the mass number of the atom. Mass number is always a round number that is natural number. The proton code for fluorine atom is 9. Mass number is the total number of protons and neutrons. So for mass number 19, the number of neutrons will be 19 - 9 = 10.
The mass number of an atom is the sum of its protons and neutrons. Since sulfur has 16 protons (its atomic number) and 19 neutrons, the mass number of a sulfur atom with 19 neutrons would be 16 + 19 = 35.
The mass number of an atom is the sum of its protons and neutrons. Chlorine (Cl) has an atomic number of 17, so it has 17 protons. If it has 19 neutrons, then the mass number would be 17 (protons) + 19 (neutrons) = 36. Therefore, the mass number of this chlorine atom is 36.
Fluorine is a non metal element. Atomic mass number of it is 19.
Fluorine has an atomic number of 9, which means it normally has 9 protons. With a mass number of 19, the total number of protons and neutrons in fluorine is 19. Therefore, subtracting the atomic number of 9 protons gives us 10 neutrons in fluorine with a mass number of 19.
Fluorine is a non metal element. Mass number of it is 19.
