Atomic number 9 - a nonmetallic univalent element belonging to the halogens; usually a yellow irritating toxic flammable gas; a powerful oxidizing agent; recovered from fluorite or cryolite or fluorapatite.

Pottasium is a meta element. Atomic 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).
Fluorine is a non metal element. Atomic mass number of it is 19.
Pottasium is a meta element. Atomic number of it is 19.
Potassium is highly reactive element. Mass number of K is 39.
Fluorine is a gas element. atomic number of it is 9.
Potassium vapor
Pottasium is a meta element. Atomic number of it is 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.
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).
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
The atomic mass 19 is for fluorine, the ist member of halogens it exists as F2,a diatomic gas.
Since the atomic number of an element corresponds to the number of protons in its nucleus, potassium with an atomic number of 19 has 19 protons.
