86 - Atomic Number ( Number of Protons )
RN (Radon)
222 - Mass Number
atomic number 86 - a radioactive gaseous element formed by the disintegration of radium; the heaviest of the inert gasses; occurs naturally (especially in areas over granite) and is considered a hazard to health.
What else can I help you with?
What is the symbol for one element that DOES NOT need eight electrons to have full set of valence electrons?
An element that does not require eight electrons for a full set of valence electrons is represented by the element symbol B. Boron only needs six electrons to complete its valence shell and achieve stability.
How many valence electrons are in the element Neon?
There are 8 valence electrons in the element Neon, as it is in group 18 of the periodic table.
Which element has a mass number of 40 and only has 2 valance electrons?
The element that has a mass number of and two valence electrons is an isotope of calcium.
What element is in the fourth period of the periodic table with a total of 3 3d electrons?
The element in the fourth period with 3 3d electrons is titanium (element #22).
The number of electrons in the outermost shell of an element is 5 what is its valency and why?
Its valency is 3 i.e. 8-5.The element is a non metal since it has 5 electrons in the outermost shell.Hence, it is very difficult for the element to loose 5 electrons and would be easier togain 3 electrons .Hence, the element gains 3 electrons and thus we consider its valencyto be 8- no. of valence electrons.
What element in the periodic table has atomic mass of 230 with 86 electrons?
Rn has 86 electrons, Th is the closest to having an atomic mass of 230
How many shells does radon have?
Radon is a non metal element. There are 86 electrons in a single atom.
Which element has 86 electrons and 82 protons?
The element with 86 electrons and 82 protons is lead, with the chemical symbol Pb. Lead is a heavy metal that is commonly used in construction, batteries, and radiation shielding due to its high density.
How is the noble gas element helium differ from radon?
Helium has 2 electrons and Radon has 86 electrons but both have 8 valence electrons (8 electrons in their outermost shells)
What element is a gas in period 6 and has 86 protons?
The element is radon (Rn), which has 86 protons. Radon is a noble gas that is located in period 6 of the periodic table.
If an element has a total of 86 electrons is it inert reactive or non reactive?
An element with 86 electrons is reactive because it is not a noble gas and does not have a full outer electron shell. Elements tend to react to achieve a stable electron configuration, such as by gaining or losing electrons to achieve a full outer shell.
How many protons are in element radon?
Radon has 86 protons and electrons; the number of neutrons is different for each isotope: Number of neutrons = Atomic mass of the Rn isotope - 86
How many electrons are in a radium atom?
The number of electrons in a radium atom is usually 88. If it goes though bonding however, it will tend to lose those two outer electrons, and become a radium ion. If it bonds with oxygen, which has 6 outer electrons, it will lose the two outer electrons it has to become a radium ion with a full outer level of 86 electrons, and oxygen will get a complete outer level of 8 electrons. Radium will become Ra2+, a typical radium ion, also known as Radium 86, as it loses 2 electrons.
What has 86 electrons125 neutrons and 82 protons?
The element with 86 electrons, 125 neutrons, and 82 protons is the element Lead (Pb). The number of protons (atomic number) determines the element, and in this case, it is 82 for lead. The sum of protons and neutrons gives the atomic mass, which is 207 in this case, making it the isotope with mass number 207.
What is the number of protons neutrons and electrons of radon?
There are 88 protons/electrons in radium. There are 138 neutrons.
What is atomic strucutre?
IT is the electrons on element IT is the electrons on element
How many electrons does the element neon?
The Element Neon has 10 protons and 10 electrons.
