There are 11 protons and 12 neutrons. And that does not depend on the Periodic Table. Sodium had 11 protons and 12 neutrons long before the periodic table, or even human, beings existed!
What else can I help you with?
How do you determine the numbers of subatomic particles in an atom based on its identity?
The number of protons in the nucleus determines the atom's identity. This is the atomic number on the periodic table. The number of electrons in a neutral atom is equal to the number of protons. Neutrons can vary, but the atomic mass on the periodic table provides an average number of protons and neutrons in an atom.
How many protons and neutrons are in florine?
no of proton is 9 and no of neutrons is also 9.
Why is the periodic number now based on the atomic number of elements and not mass number?
Because the number of protons defines the element, not the mass (you can have Hydrogen with 1 or 2 neutrons and it is still Hydrogen)
What 2 properties are the modern periodic tables based on?
It is based on atomic number. The number of protons.
How do you calculate the atomic mas based on the number of protons and neutrons of an atom?
To calculate the atomic mass of an atom, you would add the number of protons and neutrons together. Protons and neutrons each have a mass of approximately 1 atomic mass unit (amu). The sum of the protons and neutrons will give you the atomic mass of the atom in atomic mass units.
Did Mendeleev know about protons neutrons and electrons?
No, Mendeleev did not know about protons, neutrons, and electrons. He is best known for creating the periodic table of elements based on the properties of the elements without knowledge of the atomic structure. The discovery of protons, neutrons, and electrons came later with the development of atomic theory.
How do you fine the mass number?
This is based on elements. You can use a periodic table. Mass number is equals to total of neutrons and protons.

How many protons and neutrons are in florine?
no of proton is 9 and no of neutrons is also 9.
What must be true of the nucleus of atoms of a substance to call it an element?
It needs at least one proton. The periodic table is arranged, in one aspect, based on the ascending number of protons. The size and mass of the nucleus is determined by the number of protons and neutrons. Neutrons are NOT required to form an element.
Are the elements of the periodic table are arranged by the number of neutrons?
No, they are organized by numerous factors (such as free electrons and number of orbital shells) but are given their periodic number based on their electrons.No. They are arranged by the number of protons which is the same as the number of electrons.
The order of elements in a periodic table is based on?
The order of the elements in the periodic table is based on the number of protons in the nucleus. The number of neutrons decides the isotope, and the number of electrons decides the charge. For instance, Hydrogen in its most basic form is merely a single proton. This is also why the atomic weight increases throughout the periodic table as the atomic number increases.
How many protons electrons and neutrons are in europium?
In europium, the number of protons is 63, electrons is also 63, and neutrons can vary based on the isotope of europium. The most common isotope, europium-153, has 90 neutrons.
What is the name of the table that shows an element symbol and its name the number of protons and neutrons of the element?
The Periodic Table of the Elements includes most of this information (but not the number of neutrons). The Chart of the Nuclides (or Table of the Isotopes) includes all of the information.
Why is the periodic number now based on the atomic number of elements and not mass number?
Because the number of protons defines the element, not the mass (you can have Hydrogen with 1 or 2 neutrons and it is still Hydrogen)
What 2 properties are the modern periodic tables based on?
It is based on atomic number. The number of protons.
What has 8 protons 8 neutrons and 8 electrons?
Oxygen has 8 protons, 8 neutrons and 8 electrons. The symbol for oxygen is O and the atomic number is 8.
