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.
The number of protons in an atom is the definition of atomic number. For potassium, this is 19. The number of neutrons may be found by subtracting the atomic number from the mass number; in this instance 39 - 19 = 20 neutrons.
Potassium-39 has 19 protons. This is because the atomic number of an element indicates the number of protons in its nucleus, and potassium has an atomic number of 19.
19 protons
20 neutrons
19 electrons (assuming it is not ionized)
Potassium's atomic number is 19. Thus, to be electrically neutral, it must have 19 protons and 19 electrons. 39K has 39 - 19 = 20 neutrons.

How many prtons are presnt in an atom potassium -39?
A potassium-39 atom has 19 protons since the atomic number of potassium is 19.
How many protons are in K39?
bruh
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).
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.
How many electrons and neutrons are in potassium?
Potassium (K) Has the same number of electrons as protons therefore it has 19 electrons. To find the number of neutrons you take the mass of the element minus the number of protons so 39-19=20. so there are 20 neutrons in potassium.
How many prtons are presnt in an atom potassium -39?
A potassium-39 atom has 19 protons since the atomic number of potassium is 19.

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).
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).
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.
How many electrons and neutrons are in potassium?
Potassium (K) Has the same number of electrons as protons therefore it has 19 electrons. To find the number of neutrons you take the mass of the element minus the number of protons so 39-19=20. so there are 20 neutrons in potassium.
What is the mass number and symbol of an atom that contains 19 protons 19 electrons and 20 neutrons?
The mass number is always the sum of the numbers of protons and neutrons and therefore is 39 in this instance. The atomic number of 19 shows that the atom is of the element potassium, and its symbol is 39K.
How many protons are in potassium?
There are 19 protons in the potassium atom.
What is 39 in potassium?
The atomic number of potassium is 19, which means it has 19 protons in its nucleus.
What has 19 protons 20 neutrons and 19 electrons?
An atom with 19 protons, 20 neutrons, and 19 electrons is potassium-39, an isotope of potassium.
What is the atomic number and mass number for potassium?
The atomic number for potassium is 19, which means it has 19 protons in its nucleus. The mass number of potassium is approximately 39, which includes the sum of protons and neutrons in its nucleus.
