What else can I help you with?
You are a noble gas with a mass no of 19?
The element with a mass number of 19 could be fluorine, which is a halogen and a gas, but not a noble gas.
What element is a gas and has a mass number of 19?
The fluorine-19 isotope.
What element is a gas and a mass number of nineteen?
Fluorine is a non metal element. Mass number of it is 19.
Gas with mass number 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.
What element is a gas with mass number of19?
Fluorine is a non metal element. Atomic mass number of it is 19.
What is the gas with a mass number of nineteen?
The atomic mass 19 is for fluorine, the ist member of halogens it exists as F2,a diatomic gas.
What element has a mas number of 19?
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.
What atom has a mass number of 19?
Fluorine is a non metal element. Mass number of it is 19.
What is the mass number of fluorine-19?
The mass number of fluorine-19 is 18.998404 amu.
What is the mass number for fluorine -19?
Fluorine is a non metal element. Atomic mass number of it is 19.
An atom with an atomic number of 9 and a mass number of 19 would have an atomic mass of what?
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).
Fluorine's atomic number is 9 and its atomic mass is 19. How many neutrons does fluorine have?
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.
