How many valence electrons with an element with an atomic number 113 have?
The element with the atomic number 113 would fall in the 13th column of the periodic table Group IIIA. This group has an electron configuration that would end as p1 , meaning there would be 3 valence electrons.
What element has 7 valence electrons and 4 shells?
Valence electrons are the number of electrons present in the outermost shell of an atom. Now, the last shell of chlorine atom has 7 electrons in it. Therefore, there are 7 valence electrons present in an chlorine atom.

What is the name of element 113 in the periodic table?
Nihonium
Nihonium, moscovium, tennessine, and oganesson are the permanent names for elements 113, 115, 117, and 118, the International Union of Pure & Applied Chemistry (IUPAC) announced today. The permanent names for elements 113, 115, 117, and 118 are nihonium, moscovium, tennessine, and oganesson.
How many valence electrons are in the element C?
four valence electrons
Carbon has four valence electrons and here a valence of four.
How is valency calculated?
The valency of an atom is equal to the number of electrons in the outer shell if that number is four or less. Otherwise, the valency is equal to eight minus the number of electrons in the outer shell. Once you know the number of valence electrons, you can easily calculate the valency. Was this answer helpful?
Where do you find valence electrons?
outermost shell
Valence electrons are the electrons in the outermost shell, or energy level, of an atom. For example, oxygen has six valence electrons, two in the 2s subshell and four in the 2p subshell. We can write the configuration of oxygen’s valence electrons as 2s²2p⁴.
What is the chemical name of CFC 113?
1,1,2-Trichloro-1,2,2-trifluoroethane, also called trichlorotrifluoroethane or CFC-113, is a chlorofluorocarbon. It has the formula Cl 2FC-CClF 2. This colorless, volatile liquid is a versatile solvent. It has attracted much attention for its role in the depletion of stratospheric ozone.
How much CFC-113 is in the atmosphere?
The amount of CFC-113 in the atmosphere has remained at about 80 parts per trillion, since the early 1990s. It is isomeric with 1,1,1-Trichloro-2,2,2-trifluoroethane, known as CFC-113a, which has the structural formula CF 3 -CCl 3. The Montreal Protocol in 1987 called for the phase out of all CFC’s, including CFC-113 by 2010.
