The atomic number that sodium has in Periodic Table is 11 and valency is 1. The periodic table is a kind of table that was invented for the better study of elements and other types of compound. It makes the systematic study of elements.
11 is the atomic number for the element sodium in the periodic table.
NaCN stands for sodium cyanide. This is a compound and is not found on the periodic table as such. Periodic table is an arrangement of elements and not compounds. NaCN contains three elements: Sodium (Na, atomic number 11), carbon (C, atomic number 6) and nitrogen (atomic number 7).
Mass number is the number of protons and neutrons in the nucleus of an atom. Atomic number on the periodic table is the number of protons in the nucleus of an atom. mass number - atomic number = number of neutrons The atomic number of sodium is 11. Specified mass number is 23. Therefore, 23-11 = 12 neutrons
The atomic number of sodium is 11. Other numbers are 3rd period and column 1.
sodium chloride is a salt, a type of compound, not an element. it has no atomic number.
All of the others in the same row of the Periodic Table as sodium.
11. This can be found in a periodic table or other reference.
According to the modern periodic table "Elements are the periodic function of their atomic number".They are arranged in increasing atomic no. in the periodic table.
The periodic table is a function of the atomic number.
All of the elements in the same period (row) of the periodic table as sodium have this property.
Sodium reacts the most on the periodic table.It is alkali metal with atomic number 11.It forms sodium chlorine with cl.
In modern periodic table, elements are listed by increasing atomic number.
