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 to
gain 3 electrons .
Hence, the element gains 3 electrons and thus we consider its valency
to be 8- no. of valence electrons.

How many electrons does phosphorus have in its valence shell?
The atomic number of phosphorus is 15.its electronic configuration is 2,8,5.outermost shell has 5 electrons. it can accommodate 3 more electrons to complete its octet.so its valency is 3. and it has 5 electrons on its valence shell.
How many electrons are found in the outermost shell of alumimum Al atomic number 13?
The atomic number of any element depends on the number of protons it has in its nucleus. Aluminium has 13 protons hence making the atomic number of aluminum 13.
How many electrons are in a chloride ion's outermost energy level?
The chloride ion (Cl-) has 8 electrons on the outermost energy level.
The valency of oxygen is?
two , two valence electron Oxygen has two valence electrons since it must gain two in order to obtain 8 electrons in its outermost energy level. However, the number of valence electrons is six--not two. The valence and valence electrons are only the same for metals in Groups 1, 2, and 3.
What are the azimuthal quantum number for the outermost electrons in a nitrogen atom?
5
How do you find valency of elements?
The number of electrons in the outermost energy shell is usually used in finding the valency of a given element. For instance elements that have two electrons in the outermost energy shell have valency 2.
How do you find valency of an element?
The number of electrons in the outermost energy shell is usually used in finding the valency of a given element. For instance elements that have two electrons in the outermost energy shell have valency 2.
What term refers to the number of electrons found on the outermost energy level of an atom?
The term is 'Valency'
Radical - positive and negative radical in chemistry?
Valency is the number of hydrogen atoms that can combine with [or displace] one atom of the element [or radical] to form a compound. For example, one atom of hydrogen combines with one atom of chlorine to form hydrogen chloride [HCl]; so, the valency of chlorine [chloride] is one. Similarly, the valency of the nitrate radical [NO3] in the compound nitric acid [HNO3] is 1, and the valency of the sulfate radical in the compound sulfuric acid [H2SO4] is 2. For elements that do not combine with hydrogen, the valency is the combining power of the element with another element whose valency is known. Valency may also be defined as the number of electrons that an atom donates or accepts to form the duplet state (i.e., 2 electrons in outermost shell) or octet state (i.e., 8 electrons in outermost shell). The valency of an element [or radical] is always a whole number. Elements [or radicals] with valency one are monovalent, those with valency two are divalent, and those with valency three are trivalent
How do you find valency?
The valency of an element measures its ability to combine with other elements. This valency is determined by the number of electrons in the outer shell of each atom of an element.
What is the valency of elements?
The valency of an element is the number of electrons an atom of that element wants to gain, lose or share in order to be chemically stable.
What do Valence Electrons determine?
The Group Number of the Element you're working on determines the number of Valence Electrons. Valence electrons are electrons in the outside energy level.
What is velancy?
The combining capacity of an element with another element is called valencyOR The number of electron gained or lost by outermost shell of an element is called its valency
Why is chlorine written as CL2 while it has valency of 1?
Valency is the number of electrons to reach the stable number of 8 electrons in its outer shell. Electrically neutral chlorine has 7 electrons its outermost shell. This means that a single bond, where two electron orbitals overlap is required to form the stable element allotrope, therefore two atoms of chlorine are needed.
An element having atomic number 14 its valency will be?
Its valency could be 4 because it has 4 electrons in its valence shell.
What determines the group an element is placed in?
The number of electrons in the outermost orbital.
What is the total number of electrons in the outermost energy level?
The velence electron will vary for element to element and can have 1 to 8 valence electrons.
