Valency is the charge of an ion or radical which has either lost or gained electrons
Note that metals lose electrons easily to become positive ions. This is why most metals are good conductors of electricity.
A Radical is a group of atoms usually charged which can keep itself intact and behaves like a unit in a chemical reaction.
For example:hydroxide ion (OH-) and ammonium ion (NH4+).
When A compound contains more than one such radicals then the formula of this is taken in brackets with their number written on the lower right hand side.

Element 3 lithium has one valence electron and element 4 beryllium has two valence electrons Element 5 boron has how many valence electrons?
Boron has 3 valence electrons.Boron has 3 valence electrons.
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.
How can you tell from an element's number of valence elns whether the element is more likely to form a caor an anion?
If an element has less than four valence electrons, it will tend to lose its valence electrons and form cations. If an element has more than four valence electrons, it will tend to gain electrons and form anions. An element that has four valence electrons will tend to form covalent bonds rather than ionic bonds.
What are Valence elcetrons?
Valence electrons are the electrons on the outermost energy shell of an element.
What is the correct number of valence electron in the element sulfur?
six valence electrons
How many valence electrons should an element to react with a element with 7 valence electrons?
one valence electron
Element 3 lithium has one valence electron and element 4 beryllium has two valence electrons Element 5 boron has how many valence electrons?
Boron has 3 valence electrons.Boron has 3 valence electrons.
Is the element reactive or satble how do you know?
If the element has a full valence shell, such as the noble gases, then it is unreactive. It the element is missing few valence electrons of has few valence electrons, then the element is very reactive, such as the sodium.
What type of properties do valence elcectrons determine for an element?
Valence electrons determine the reactivity of the element.
What is a univalent radical?
A univalent radical is an atom, molecule or ion that has only one open electron available for bonding, or one valence. Hence, univalent radical.
Why is so much emphasis placed on valence electrons?
The valence electrons of an element are mainly what determine an element's properties.
What is the expected number of valence electrons for a group 3 A element?
The expected number of valence electrons for a group 3 A element is 5 number of valence electrons.
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.
How many valence in the element cobalt?
There are 2 valence electrons in cobalt.
How can you tell whether or not an element will react with others element?
Depending on how many valence electrons in the element has, The other element could take away a valence electron to make eight
What element has more valence electrons than oxygenfewer valence electrons than neon more protons than sodium but fewer protons than argon?
Neon has 0 valence electrons so it is not possible to have an element with fewer valence electrons. There can, therefore, be no such element.
