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.

Is mass number the combining capacity of an element?
No, mass number is the number of neutrons and protons that exist within the nucleus of the atom for a particular element. It is based on the idea that most of the mass of an atom derives from the nucleus.
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 do you know how many unpaired electrons are in an element?
You can determine the number of unpaired electrons in an element by examining its electron configuration. Unpaired electrons are found in the outermost energy level, and you can count them by looking for half-filled or singly occupied orbitals in the notation of the element.
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.
What are the azimuthal quantum number for the outermost electrons in a nitrogen atom?
The outermost electrons in a nitrogen atom have an azimuthal quantum number of 1, which corresponds to the p orbital.
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.
What is the valency of elements?
The valency of an element is its combining power with other elements to form compounds. It is determined by the number of electrons an atom needs to gain, lose, or share to achieve a stable electron configuration. The valency of elements can vary depending on the number of electrons in their outermost energy level.
How do you calculate the valency of an element from its electronic configuration?
To calculate the valency of an element from its electronic configuration, determine the number of electrons in the outermost shell. The valency is typically the number of electrons needed to complete the outermost shell to achieve a stable octet (eight electrons). For example, elements in group 1 have a valency of 1, while elements in group 17 have a valency of 7.
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'
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.
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
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 difference between valency and valence electron?
valence electrons are on the outer shell. they're the ones that will interact with other molecules as bonds are formed. electrons on inner shells don't interact with other molecules. they keep to themselves.
Is the valency of an element same as its oxidation number?
Sometimes yes ... sometimes no. Valency of chlorine is 7 ... it has 7 valence electrons. But its most common oxidation number is -1.
What are Valence elcetrons?
Valence electrons are the electrons in the outermost energy level of an atom. They are involved in chemical bonding and determine the reactivity of an element. The number of valence electrons influences the element's properties and behavior in chemical reactions.
