Where is the location of the neutrons in a periodic table?
Neutrons are not given directly on the periodic table. However the number of neutrons can be indirectly calculated. Mass number = Number of protons + number of neutrons
How many numbers of neutrons does magnesuim have?
Magnesium (Mg), number 12 on the periodic table, has 12 neutrons.
How are atomic numbers and mass numbers of elements arranged in the periodic table?
by ectron protons and neutrons
The number of neutrons in the nucleus of an atom can be calculated by what?
The number of neutrons in the nucleus of an atom can be calculated by subtracting the number of protons (atomic number) from the atomic mass of the atom. Atomic mass - Atomic number = Number of neutrons.
What is the element group number and period number?
The numbers on the left side of the table are the period numbers and on the top are the group numbers.
Why don27t elements in the periodic table have whole numbers for their atomic masses?
Because the masses of protons, neutrons and electrons are not whole numbers.
What 2 numbers are shown in tye periodic table for each element?
The number above the symbol is the atomic number, or the number of protons in the nucleus of one atom of the element. It is this number by which they organized the periodic table. If this number changes so does the identity of the element. In a balanced atom this number will also be the number of electrons in the electron cloud. The number below is the atomic mass number, or the average number of particles (protons plus neutrons) in the nucleus. Since the number of neutrons can change this number must be given as an average so it may contain a decimal.
What does the numbers on the side of the periodic table represent?
The period to which the element belongs
Where is the period number found on the periodic chart of the elemnts?
Usually at the top ... and classically written in Roman numerals.Yes, there are numbers at the top of a periodic table, although they are for the groups/families on the periodic table. Usually the period numbers are found to the left of the periodic table.
How do you find the mass number on the periodic table for the elements are calculated?
The mass number is the number of protons plus the number of neutrons in the atomic nucleus.
What do the period numbers on the periodic table?
There are 7 periods. These describe number of shells.
Transition element 51 neutrons period 10?
The element with 51 neutrons is antimony (Sb), which is a metalloid. Being in period 5, it belongs to the transition elements in the periodic table, showing typical metallic properties and variable oxidation states in its compounds.
