Which element has highest valency?
The element with the highest valency is fluorine, which has a valency of 7. This means that fluorine can form compounds by gaining one electron to complete its outer shell and reach a stable electron configuration.
What is the formula for valency?
The valency of an element is determined by the number of electrons it gains, loses, or shares to achieve a stable electron configuration. It is typically the same as the number of electrons an element needs to gain or lose to achieve a full outer shell (octet). For example, elements in Group 1 have a valency of +1 because they lose one electron to achieve stability, while elements in Group 17 have a valency of -1 because they gain one electron to achieve stability.
What is the valency of an element with example?
== == The valency of an element is the measure of electrons it needs or needs to loose to obtain a stable structure (a noble gas structure, such as helium, neon, argon ...) for example in NaCl, sodium has 11 electrons which means 1 valence electron, chlorine has 17 electrons which means it has -1 valence electrons; so sodium looses 1 electron and chlorine gains that electron so sodium ends up with 10 electrons (Neon's electron structure) and chlorine ends up with 18 electrons (Argon's electron structure) the number of outer electrons. Noble elements are the most stable elements (thats why they don't react well and stay alone, like helium) so all the other elements try to obtain the noble electron structure. Elements usually gain or loose 4 electrons.
What is the valency of fluorine?
The valency of fluorine is 1. It typically forms one bond by gaining one electron to achieve a full outer electron shell.
Why you take the valency of helium 0?
Noble gases have electronegativity values of zero because they have completed the fulfillment of their orbitals and are no longer looking to bond with anymore electrons. There are exceptions with Krypton, Xenon, and Radon though.
What is the valency of lithium?
The valency of lithium is 1. It has one valence electron in its outer shell.
What is the valency of helium be?
helium's valency is zero as id does not combine with other elements
What is the valency of helium?
Helium has a valency of 0 because it has a full outer shell with 2 electrons, making it stable and unreactive.
What is the electron number for helium?
two
Which element has highest valency?
The element with the highest valency is fluorine, which has a valency of 7. This means that fluorine can form compounds by gaining one electron to complete its outer shell and reach a stable electron configuration.
Why do helium neon argon have a 0 valency?
Noble gases such as helium, neon, argon etc have completely filled valence orbitals, and hence have sable electronic configuration. They do not form bond with other elements. In other words, they are chemically inert and have zero valency.

What is meant by valency orbit and valency electron?
A valance electron is one that is associated with an atom. The valence orbit is the one that electron travels in.
How calculate valency?
Valency is calculated in this way... 1. Find atm no of that element. 2. Write down electronic configuration. 3. Take the valence shell electron number. 4. The number of electrons to be lost are added as the valency.
What is called valency of an electron?
In fact an electron has no valency, though it is equal to a -1 (minus one) charged anion like Cl-, having a valency of -1
How do you find out valency of manganese?
The valency of manganese can be determined by looking at its electron configuration. Manganese typically forms compounds in which it has a valency of +2, +3, +4, +6, or +7 depending on the specific compound it forms. This valency corresponds to the number of electrons that manganese can lose or gain to achieve a stable electron configuration.
What is the valency of hydrogen and why?
The valency of hydrogen is +1 because it has a tendency to lose an electron while combining with an Elelment. This gives it a positive valency.
