The number of an element on the Periodic Table is equal to the number of protons in a single atom of that element.
Since Mercury (symbol Hg) has the atomic number of 80, this means there are 80 protons in a single atom of mercury.
The interesting fact is that scientists have categorized the known elements only based on the atomic number. Atomic number is nothing but the number of protons present in the core or nucleus of the atom. In a funny way, we can say that the elements live in their own flats with some definite door number in the periodic apartments.
Thus the flat number for mercury is 80. Because of 80 protons are present in the nucleus of mercury atom.
The neighbouring resident to mercury is gold as its flat number is 79. Another neighbour is Thallium whose atomic number is 81.
So it has become possible to change mercury into gold by the physical means not by chemical means. That means, the transmutation is only possible as we change the number of protons present in the nucleus (termed as physical change) not by changing configuration of electrons around the nucleus in the atom, which is termed as chemical change.
In ancient days people were crazy to make gold out of other metals especially base metals. They were named as Alchemists.
Finally Rutherford declared that such transmutation is only possible by Physical not by Chemical.
Mercury, that curious metal which is liquid at room temperature and was know to the ancients, has 80 protons in its nucleus.
There are 80 protons and 80 electrons in Mercury
The atomic number of mercury will tell you this (the atomic number = number of protons (and electrons)). The atomic number of Mercury is 80.
80.
Well in mercury, the ammount of neutrons is 121. the ammount of protons is the same as the atomic number and electrons which is 80.
80; it's the atomic number typically in the top left corner
Mercury has 80 protons.
80 protons, 80 electrons
how many protons are in mercury
The amount of electrons in mercury is (80)electrons.
Experimentally, I'm not sure, but I know you can look at your periodic chart, the large number over the symbol of each element is teh number of protons in that element.
Each element has a unique number of protons. If another atom has the same number of protons as that element, it is the same element.
The atomic number of the element refers to the number of protons of an atom: all atoms of an element have this number of protons. A neutral atom of the element will have the same number of electrons.
Each atom of an element has the same number of protons which is unique for that particular element ( = atom number in the periodic system)
The element mercury has 80 protons.
The number of protons is different.
Each chemical element has a specific number of protons; the number of protons is equal to atomic number of the element.
Mercury is a metal element. Atomic number of it is 80.
The amount of electrons in mercury is (80)electrons.
Mercury (Hg) has an average atomic mass of 200.59. This is an average based on the percentages of the naturally occurring isotopes of Mercury. There is an isotope of Mercury that has 201 particles in the nucleus. Since Mercury's atomic number is 80, Mercury-201 has 80 protons and 121 neutrons in its nucleus.
By the number of protons in the nucleus. So the atomic number decides the element. If it is 1, then that is Hydrogen element. 2 is for Helium, 3-Lithium, 4-Berilium, 5-Boron and so on. Gold element has 79 protons in its nucleus. Mercury has 80. So with a high sophisticated technology if we take only one proton from each mercury atom, then we can produce gold. So mercury has been changed into gold. So transition of element is only by physical means not by chemical means.
The identity of an element is determined by the number of protons in the nuclei of its atoms. This is the atomic number of an element.
Experimentally, I'm not sure, but I know you can look at your periodic chart, the large number over the symbol of each element is teh number of protons in that element.
There are many different types of elements, all varying in the number of protons they contain. To determine the number of protons in a specific element, refer to the periodic table of elements. The atomic number (generally listed above the element's symbol, sometimes represented as 'Z') is equal to the number of protons in that atom.
By definition, the number of protons in the atoms of an element is the atomic number of the element.
Each element has a unique number of protons. If another atom has the same number of protons as that element, it is the same element.
