How many protons are in the Hg atom?
The element mercury (Hg) has 80 protons and 80 neutrons. It exists in several different isotopes which have different numbers of neutrons, however, the average number of neutrons in a mercury atom is 121. (The atomic weight is 200.59 which would require 80 protons and 120.59 neutrons, although of course every atom has only whole numbers of neutrons, you only get fractions because you are getting an average of different isotopes.)
An element is determined by what?
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.
What element results if you add a pair of protons to the nucleus of mercury?
Assuming that two neutrons and two electrons are also added, the atomic number would shift from 80 to 82, resulting in lead. If the neutrons or electrons were not added, it would be the radioactive isotope, lead-206.
If an atom has 35 electrons and its mass number is 80 calculate the number of protons?
In a neutral atom, the number of electrons will be the same as the number of protons. This is because one positive proton will cancel out one negative electron; therefore, if the atom is neutral, it must have the same number of protons and electrons.The number of protons is also the same as the atomic number. For this example, Bromine, with the atomic number of 35, has 35 protons.Bromine:Atomic number- 35Number of protons- 35Number of electrons- 35The mass number is the sum of the atomic number (or number of protons/electrons) and the neutrons. For this example, we know the atomic number (35) + # neutrons = mass number (80). To figure out the number of neutrons, take the mass number and subtract the number of electrons/protons/atomic number. Mass number (80) - atomic number (35) = neutrons (45).
How many electrons does Mercury have on all of its energy levels?
The electron configuration for mercury is this: 1s2 2s2 2p6 3s2 3p6 3d10 4s2 4p6 5s2 4d10 5p6 4f14 5d10 6s2 Mercury is element 80. That's its atomic number, and there are 80 protons in its nucleus. If a mercury atom is neutral, it will have 80 electrons about it, and the electrons will be arranged as outlined above.
What is an electrically neutral atom of mercury?
80 electrons, 80 protons
How many protons are in the Hg atom?
The element mercury (Hg) has 80 protons and 80 neutrons. It exists in several different isotopes which have different numbers of neutrons, however, the average number of neutrons in a mercury atom is 121.

What isotope has 80 protons 80 electrons and 121 neutrons?
It is the Sr+2 ion. It is formed by a Sr atom.
If an atom has 80 protons and 121 neutrons and is not in an excited state how many electrons does the atom have?
80
What is the number protons in the nucleus?
The number of protons in the nucleus is equal to the atomic number of that atom. Said another way, the atomic number of any element is the number of protons in the nucleus of any atom of that element.It might be helpful to consider some examples, and if we look at mercury, we'll see it has an atomic number of 80. All atoms of mercury have 80 protons in them. Aluminum has the atomic number of 13, so all atoms of it have 13 protons in them. Uranium, which has atomic number 92, has 92 protons in all of its atoms.The number of electrons and neutrons in a given atom of a given element can vary for a number of reasons, and these characteristics are considered separately. The number of electrons in any atom will match the number of protons in the nucleus of that atom only if the atom is a neutral one. Some atoms loan out or borrow electrons, and then they become what are called ions. The number of neutrons can vary, too, and we use the term isotope to talk about atoms of a given element having different neutron counts.The atomic number indicates the number of protons in an atom's nucleus.The number of protons in the nucleus is the atomic number of the atom.
The nucleus of an atom consists of 8 protons and 6 neutrons The total number of electrons present in a neutral atom of this element is?
Atomic number 76 is Osmium, the densest element. Its atomic mass is 190. Atomic number tells you the number of protons, so 76 protons. Atomic mass tells you the sum of protons and neutrons, so there are 190-76 = 114 neutrons.
How many protons neutrons electrons does bromine 80 have?
Br-80 has 35 protons, the element has 35 electrons (bromide anion has one more), and 80-35=45 neutrons.
What element has the least protons of mercury helium uranium nitrogen?
Helium, with only two protons per atom. In contrast, nitrogen has 7, mercury has 80, and uranium has 92.
What is inside of a mercury atom?
80 protons, 80 electrons, 121 neutrons

How many particles are there in the nucleus of an atom of mercury?
there are 80 protons in the nucleus of an atom of mercury
How many protons are in a boron?
The element boron has atomic number 5; therefore, there are 5 protons in each boron atom, because the atomic number of an element is defined as the number of protons in each atom of an element.
