Mercury is normally considered to have 2 valence electrons- its configuration is 5d106s2. Mercury was long believed not to use any other electrons in forming bonds and is called a post transition element.
However the compound HgF4 was discovered in 2007. It can only be isolated by trapping at at very low temperatures (solid neon gas temperature) so in practical every day terms the 2 valence electron rule holds.
What else can I help you with?
How many electron shells does mercury have?
There are two valence electrons in a mercury molecule. Mercury is known commonly as quicksilver. It is also registered as the symbol Hg.
What is the mass number of Hg?
Mercury is a metal element. Atomic number of it is 80.
Do mercury form ions by the loss of electrons?
Yes, mercury can form ions by the loss of electrons. It typically does so by losing one or two electrons, resulting in the formation of cations such as Hg⁺ and Hg²⁺. These ions can participate in various chemical reactions, influencing the behavior and properties of mercury in different environments.
Of the metals Pb Hg Na and Ca which is the most difficult to oxidize?
Mercury (Hg) is the most difficult to oxidize among the metals lead (Pb), mercury (Hg), sodium (Na), and calcium (Ca). Mercury has a unique electronic configuration that makes it reluctant to lose electrons and be oxidized.
What is the symbol for Mercury in the Periodic Table of Elements?
The chemical symbol for mercury is Hg. The atomic number for the element is 80. It is one of the only liquid elements on the table.
How many electrons are present in an atom of mercury 201?
121 neutrons.
What is the symbol and number of protons in one atom of Mercury?
The symbol of Bromine is Br and number of protons(or atomic number) which is also equal to the number of electrons is 35

The chemical symbol for element Mercury is?
Hg is the chemical symbol for mercury
How many d electrons does Hg have?
Mercury (the neutral atom) has 8o electrons.
What is the oxidation number of mercury 1?
+1 for Hg in the Hg22+ ion
How many protons and electrons does mercury have?
Mercury (Hg) can ONLY have 80 protons, or else it cannot be mercury. The difference between its mass number (201) and 80 is 121, which is the number of neutrons. These can vary and are called isotopes. The number of protons can always only be 80 for mercury, tho.
What is the symbol and the number of mercury?
We use Hg as the symbol. Atomic number of Hg is 80.
What is the mass number of Hg?
Mercury is a metal element. Atomic number of it is 80.
Do mercury form ions by the loss of electrons?

These ions can participate in various chemical reactions, influencing the behavior and properties of mercury in different environments.
Who has 80 electrons transition element?
Electrons each have a charge of -1. So, if the element we're trying to find is electrically neutral, it needs to have 80 protons to balance out the 80 electrons. If you look at a periodic table, you will see that this element is mercury, or Hg.
Of the metals Pb Hg Na and Ca which is the most difficult to oxidize?
Mercury (Hg) is the most difficult to oxidize among the metals lead (Pb), mercury (Hg), sodium (Na), and calcium (Ca). Mercury has a unique electronic configuration that makes it reluctant to lose electrons and be oxidized.
