How many electrons are in an atom of mercury-202?
Diagram of the nuclear composition and electron configuration of an atom of mercury-202 (atomic number: 80), the most common isotope of this element. The nucleus consists of 80 protons (red) and 122 neutrons (blue). 80 electrons (green) bind to the nucleus, successively occupying available electron shells (rings).
How many neutrons are in mercury 205?
So, there must be 201 – 80 = 121 neutrons . Since atoms are electrically neutral, there must be as many electrons as there are protons. A mercury atom needs 80 electrons to balance the 80 protons.
What has a mass number of 204?
Lead , isotope of mass 204 | Pb – PubChem.
Is mercury toxic?
Health effects of mercury exposure
Elemental and methylmercury are toxic to the central and peripheral nervous systems . The inhalation of mercury vapour can produce harmful effects on the nervous, digestive and immune systems, lungs and kidneys, and may be fatal.
Which is heaviest 25g of HG?
Hence the correct option will be (C) “ 2 moles of carbon dioxide” is heaviest. Note: Water and Mercury which is a silvery-white, shiny metal, are liquid at room temperature.
What is the smallest particle of mercury?
electron O molecule atom proton .
Where is mercury found?
Mercury is a very rare element found in the Earth's crust . It is sometimes found in its free state, but is usually found in ores such as cinnabar, livingstonite, and corderoite. Most mercury today is produced from the mining of cinnabar, a bright red ore.
Is mercury a heavier element than tin?
Yes, mercury is heavier than tin . Mercury and tin are both elements. To find which is heavier, you need to look at the periodic table.
Is the planet Mercury radioactive?
The average surface abundances of radioactive elements on the surface of Mercury north of ~20°S are 1150 ± 220 parts per million (ppm) K, 220 ± 60 parts per billion (ppb) Th, and 90 ± 20 ppb U.
What has an atomic number of 81?
Thallium is a chemical element with the symbol Tl and atomic number 81.
Which element has a mass number of 201?
