Pottasium is a metal element. atomic number of it is 19.
Only elements have a particular (unique) atomic number. Potassium (K) has 19 and chlorine (Cl) has 17 as atomic number (= proton number)
The mass number, the number that follows the hyphen at the end of an element name, is the sum of the atomic number of the element and the number of neutrons in each atom of the isotope specified by mass number. The atomic number of potassium is 19; therefore, potassium-39 contains (39 - 19) or 20 neutrons.
'Potassium' is the name. Its Latin name is KALIUM (K) its formula symbol. Atomic No. is 19 ; 19th position in the Periodic Table.
Symbol - F Atomic Number - 9 Mass Number - 19
The atomic number by definition is the number of protons in the nucleus, therefore 19 in this instance. (The isotope effectively specified by the numbers given in the question is potassium-40, which is least commonly occurring natural isotope of potassium.)
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).
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
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.
Pottasium is a meta element. Atomic number of it is 19.
Fluorine is a non metal element. Atomic mass number of it is 19.
Pottasium is a meta element. Atomic number of it is 19.
Only elements have a particular (unique) atomic number. Potassium (K) has 19 and chlorine (Cl) has 17 as atomic number (= proton number)
Potassium is highly reactive element. Mass number of K is 39.
The atomic number indicates the number of protons (19) and electrons (19).
Use the Periodic Table to get Atomic number (19), and atomic mass (39.1). The atomic number is the number of protons, and in the neutral atom, also the number of electrons: 19. The atomic mass is the sum of the mass of the protons and neutrons, 39.1. Subtract the number of protons (use integers) from the atomic mass, 39 - 19 = 20, which is the number of neutrons. Protons = 19 Neutrons = 20 Electrons = 19
The atomic number of potassium (K) is 19.The atomic weight of K is 30.0983 grams per mole.See the Web Links to the left of this answer for a periodic table with more information about this element!I believe the atomic weight is 39.0983.19
