Look at the Periodic Table to see which of these has the greatest atomic number. In reverse order: silver, gold, Mercury, lead (82)
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.
Is the number of protons in an atom determines its atomic number
The sum of the neutrons and protons is the mass number (A)In this problems,the answer for mass number of mercury isotope is:80 protons + 120 neutrons = 200
The atomic number is equal to the number of protons in the nucleus and in a neutral atom will also equal the number of electrons.
nass number is the number of neutrons plus protons in the nucleus of an atom
There are 80 protons in mercury-204 because the atomic number of mercury is 80, which is equal to the number of protons in its nucleus.
The elements with the highest atomic numbers have the greatest numbers of protons in their nucleus, because that is the definition of atomic number.
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 number of protons in an atom's nucleus is the Atomic number.
Is the number of protons in an atom determines its atomic number
The number of protons in an atom's nucleus determines its chemical identity.
The number of protons in a nucleus depends on which element it is. ( The number of protons is the decider as to which element it is. ) The number of electrons in an atom is the same as the number of protons in the nucleus, but none of the electrons are in the nucleus. Rather, they orbit around the nucleus like planets round a star.
The number of protons in the atomic nucleus is equal to atomic number.
The number of protons in the atomic nucleus is equal to the atomic number of an element.
The sum of the neutrons and protons is the mass number (A)In this problems,the answer for mass number of mercury isotope is:80 protons + 120 neutrons = 200
The number of protons in the nucleus of an atom.
The number of protons in the nucleus is the same as the atomic number.
