Best Answer

Atoms of the same element usually have the same number of protons but differ slightly in the number of neutrons. The number of neutrons are usually about the number of protons so it can be estimated as so.

For example, there are two relatively common isotopes of sodium: sodium 22 and sodium 23, where the number is the total number of protons and neutrons. Sodium 22 has 11 neutrons and sodium 23 has 12 neutrons but the sodium atom has 11 protons.

For further information, look up isotopes.

Atoms of the same element have the same number of protons, which defines the element, but they can have different numbers of neutrons, leading to different isotopes of the element.

Specifying a number of protons and a number of neutrons not only restricts the specified material to one element, but also to a single isotope.

The number of protons and the number of electrons will be the same which will be equal to the atomic number of the atom.

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 does the atoms have?

Atoms have varying numbers of neutrons depending on the element. The number of neutrons can be calculated by subtracting the atomic number (number of protons) from the atomic mass of the atom.


Do all atoms of the same element have the same number of isotopes?

No, atoms of the same element can have different numbers of isotopes. Isotopes of an element have the same number of protons but different numbers of neutrons, resulting in variations in their atomic mass.

Can you tell from the periodic table how many neutrons are in an atom?

No. Atoms on the Periodic Table are listed by element in order of atomic number, which is the number of protons an atom contains. The number of neutrons in the atoms of an element usually varies among several isotopes.

What you mean when you say that a particular element consists of several isotopes?

When an element has several isotopes, it means that there are multiple forms of that element with different numbers of neutrons in their atomic nuclei. Isotopes of an element share the same number of protons but differ in their neutron count. These isotopes have similar chemical properties but may exhibit variations in atomic mass and stability.
