20 neutrons

Potassium has 20 neutrons.

What is a liquid with only one type of atom?

When a substance contains only one type of atom it is called an element.

What is the number at the end of an isotope’s name?

Answer Expert Verified The number of protons and electrons remain same for two isotopes. This means isotopes have different mass number but have same atomic number. When we write an isotope the number at the end of the isotope’s name is the mass number.

How many neutrons are in potassium 41?


Potassium-41 – It has 19 protons and atomic mass is 41. Hence number of neutrons is 41 – 19 which is 22.

How many neutrons are in potassium-40?


Names potassium-40 K-40
Protons 19
Neutrons 21
Nuclide data

How many neutrons do potassium 39 and potassium 41 have?

Since K is atomic number 19 it has 19 protons. It would need 20 neutrons to get to K 39. So K 41 has 19 protons and 22 protons. The difference between each of those isotopes is 2 neutrons.

How many electrons are in potassium ion?


1.17: Ions
Element Protons Electrons
Potassium atom 19 19
Potassium ion 19 18
Sulfur atom 16 16
Sulfur ion 16 18

How many protons neutrons and electrons are there in potassium ions K 1?

19 protons 20 neutrons and 18 electrons.

How do you calculate the atomic mass of potassium?

To calculate Molar Mass multiply the number of atoms of the element by Atomic mass. Therefore the Molar Mass of Potassium is 39.0983 g/mol.

Why is potassium an atomic element?

Potassium is a chemical element with the symbol K (from Neo-Latin kalium) and atomic number 19. Potassium is a silvery-white metal that is soft enough to be cut with a knife with little force.
Standard atomic weight Ar std(K) 39.0983(1)
Potassium in the periodic table

How many neutrons does potassium 33 have?

The number of neutrons in the isotope can be calculated from its mass number which is written as a superscript in a nuclear symbol. Therefore there are 21 neutrons in this isotope of potassium (K).

How many protons and neutrons are there in a potassium atom that has a mass number of 39 and an atomic number of 19?

Explanation: Protons (the atomic number) and neutrons both contribute to the atomic mass. If you therefore subtract the number of protons (19) from the atomic mass (39) you are left with the number of neutrons (=20).

How many atoms are in an element?

An atom is an element. The two words are synonymous so if you’re looking for the number of atoms in an element the answer is always one and only one.

What substances are made up of atoms?

What is made up of only one type of particle?

A chemical element is a substance that is made up of only one type of atom. Atoms are made up of protons neutrons and electrons.

What is the number at the end of an isotope’s name atomic number neutron number?

– The liquid contains only one element. -The liquid is a pure substance. The number at the end of an isotope’s name is the -mass number. While looking at xenon (Xe) on the periodic table a student needs to find an element with a smaller atomic mass in the same group.

What is the mass number of a potassium K atom that has 20 neutrons?


An atom of potassium with 20 neutrons would have a mass number of 39 and thus be an atom of the potassium-39 isotope.

How is the name of each element in the periodic table represented?

In the typical periodic table each element is listed by its element symbol and atomic number. For example “H” denotes hydrogen “Li” denotes lithium and so on. Most elements are represented by the first letter or first two letters of their English name but there are some exceptions.

How many protons neutrons and electrons does potassium-41 have?

Potassium-41 is composed of 19 protons 22 neutrons and 19 electrons.

How do you find the atomic number?

Now you know that atomic number = number of protons and mass number = number of protons + number of neutrons. To find the number of neutrons in an element subtract the atomic number from the mass number.

What are atoms measured in?

atomic mass units

They measured atomic weights in terms of atomic mass units (amu) where 1 amu was equal to one-twelfth of the mass of a carbon-12 atom.

How many neutrons are in an atom of 14c?

eight neutrons

For example carbon-14 is a radioactive isotope of carbon that has six protons and eight neutrons in its nucleus. We call it carbon-14 because the total number of protons and neutrons in the nucleus also known as the mass number adds up to 14 (6+8=14).

What is the element symbol of potassium?


How many protons and neutrons are in an atom of K 39?

3919K 19 39 K has 19 protons and 20 neutrons.

What does the 39 mean in potassium 39?


Filters. (physics) The major stable isotope of potassium 3919K having nineteen protons and twenty neutrons it amounts to over 93% of the element in nature. noun.

What is the atomic number of 41 K?


Properties of Potassium-41 Isotope:
Properties of Potassium-41 Isotope: POTASSIUM-41
Atomic Number (Z) 19
Mass Number (A) 41

Proton Number (Z) 19

How many ions does potassium have?

Potassium ions have a charge of 1+ while sulfate ions have a charge of 2−. We will need two potassium ions to balance the charge on the sulfate ion so the proper chemical formula is K 2SO 4. Calcium ions have a charge of 2+ while nitrate ions have a charge of 1−.

What is the mass number of potassium?

39.0983 u

How many neutrons and electrons are in potassium?

This tells you that potassium has 19 protons and – since the number of protons is the same as the number of electrons- also 19 electrons. To find out the number of neutrons you have to look at the atomic mass or weight of the element. This can also be found in the periodic table.
