What is the mass atomic number of potassium?
Name: PotassiumSymbol: KAtomic Number: 19Atomic Mass: 39.0983 amuThe 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.
What is the mass number for patasium?
Potassium is a metal element. Atomic mass of it is 30.
How many neutrons occur in potassium with a mass number of 39?
Potassium with a mass number of 39 has 20 neutrons. The mass number of an element is the sum of its protons and neutrons. Since the atomic number of potassium is 19 (number of protons), the number of neutrons can be calculated by subtracting the atomic number from the mass number.
What does K 19 and 39.098 represent on a periodic table?
K is the symbol for potassium. 19 is the number of protons and 39.098 is the mass number (Protons + Neutrons + Electrons).
Explain how you would calculate the number of neutrons in potassium -40?
To calculate the number of neutrons in an atom of potassium-40, subtract the atomic number (which is 19 for potassium) from the mass number (which is 40 for potassium-40). So, 40 (mass number) - 19 (atomic number) = 21 neutrons in potassium-40.
What is an atom of potassium's atomic number and mass number?
The atomic number of potassium is 19.The atomic weight of potassium is 39,0983(1).The mass number of the isotope potassium-39 is 39.
What is the nearest whole number of atomic mass of potassium?
The nearest Whole number of atomic mass of potassium is 69
Which element has an atomic number of 19?
Fluorine is a non metal element. Atomic mass number of it is 19.
What is the atomic mass of potassium?
The atomic mass of potassium is approximately 39.10 atomic mass units.
What is the atomic and mass number of potassium?
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.

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.
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).
What is the mass number for patasium?
Potassium is a metal element. Atomic mass of it is 30.
What are potassium's atomic symbol and number?
Potassium is highly reactive element. Mass number of K is 39.
An atoms of potassium has atomic mass of 39 amu and an atomic number it therefore has neutrons in its nulces?
An atom of potassium with an atomic number of 19 has 20 neutrons in its nucleus. This can be determined by subtracting the atomic number from the atomic mass (39 - 19 = 20).
How many neutrons occur in potassium with a mass number of 39?
Potassium with a mass number of 39 has 20 neutrons. The mass number of an element is the sum of its protons and neutrons. Since the atomic number of potassium is 19 (number of protons), the number of neutrons can be calculated by subtracting the atomic number from the mass number.
