What is the mass number of an element has 19 protons 19 electrons and 20 neutrons?
19
How many protons neutrons and electrons are in k39?
In potassium-39 (K-39), there are 19 protons (since it's the element potassium), 20 neutrons (subtracting the element's atomic number from its atomic mass), and 19 electrons (since atoms are electrically neutral).
What element has 9 electrons 9 protons and 10 neutrons?
The element is Neon and the isotope is 10Ne19
What will be the element name of an atom with 9 potons and 10 neutrons?
Fluorine. Number in periodic system = Number of protons
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 is the mass number of an element that has 19 protons?
Fluorine is a non metal element. Mass number of it is 19.
Which element has 19 protons 35 electrons 2 neutrons and 201 particles in the nucleus?
This element doesn't exist.
How many protons electrons and neutrons in the element potassium?
The atomic number of potassium is 19. So there are 19 protons and 19 electrons. The number of neutrons depends on the isotope. The most stable isotope of potassium (K-39) has 20 neutrons (39 - 19 = 20).
Which element has 10 neutrons is a nonmetal and has an atomis mass greater than 19?
Neon
How many protons and neutrons are in potassium?
Potassium has the atomic number 19; that means it has 19 protons. The number of neutrons - as with any element - depends on the specific isotope. For more details, check the Wikipedia article on "Isotopes of potassium".
What atoms are in potassium?
Which potassium atom do you want? At what level do you want to count particles?potassium-38: either 19 protons & 19 neutrons or else 114 quarkspotassium-39: either 19 protons & 20 neutrons or else 117 quarkspotassium-40: either 19 protons & 21 neutrons or else 120 quarkspotassium-41: either 19 protons & 22 neutrons or else 123 quarkspotassium-42: either 19 protons & 23 neutrons or else 126 quarkspotassium-43: either 19 protons & 24 neutrons or else 129 quarkspotassium-44: either 19 protons & 25 neutrons or else 132 quarksI hope you did did not mean to count either the mesons or gluon that's convey the strong force in each case.
How many protons does potassium 39 have?
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.
