When fluorine bonds with another element the electrons do what?
Fluorine has a stronger attraction to electrons than any other element, so when it bonds to another element that element is going to either donate electrons to the fluorine, or share electrons with fluorine getting the disproportionate share.
What is the symbol for one element that DOES NOT need eight electrons to have full set of valence electrons?
The element is helium, with symbol He.
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.
Electrons of the 19th element?
The 19th element is potassium, which has the atomic symbol K. It has 19 electrons, including one valence electron that can be easily lost.
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 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
Which element has 86 electrons and 82 protons?
Pb+4, Lead
What element is a gas in period 6 and has 86 protons?
Radon. Because it has 86 protons, it has 86 electrons, so therefore, the atomic number is 86 on the periodic table.
How many shells does radon have?
Radon is a non metal element. There are 86 electrons in a single atom.
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)
If an element has a total of 86 electrons is it inert reactive or non reactive?
This is radon, it has a full outer shell of electrons, so it is technically non reactive
In the formula XBr2 if the ion of element x has a mass of 230 and 86 electrons what is the identity of the element and how many neutrons does it have?
it would be an isotope of Radon, (Radon-230)
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
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.
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.
