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.

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.
Atoms of the same element having different sums of protons and neutrons are called?
These atoms are called isotopes.
How many protons and neutrons and electrons does the element gold have?
Gold (Au) has 79 protons, 118 neutrons, and 79 electrons.
How a proton differ from an element?
Element is made by atom. atoms included many protons,neutrons and electrons.
How many atoms neutrons and protons are in a element with an atomic number of 8?
15.999 or 16.000
What tells you how many atoms of an element there are?
the atomic mass, which is the mass of its protons and neutrons and electrons together
How many protons and neutrons are in the element?
Neon has 10 protons and 9 neutrons.
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.
What are the basic unit of a chemical element called?
many identical atoms Answer is= Atoms.
How many protons an neutrons does an oxygen atom have?
8 protons and neutrons does an oxygen of an atomOxygen atoms have 8 protons and most of the time 8 neutrons.
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.
How many protons and neutrons are there in the element scandium?
21 protons and 24 neutrons in the only stable for. But there can be as few as 15 and as many as 39 neutrons.
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.
