The valence electrons in a metal are held in delocalised orbitals which cover the whole lattice. This means that they are free to move through the whole structure. This freedom gives metals their special properties such as good electrical and thermal conductivity (because the electrons move easily) and malleability and ductility (because they bond the atoms together in any configuration).

What is the group of elements with the same number of valence electrons?
Elements in the same group on the periodic table have the same number of valence electrons. Valence electrons are the electrons in the outermost energy level of an atom and determine an element's chemical properties.
Valence electrons are responsible for the makeup of the chemical properties of elements?
Yes, valence electrons are the outermost electrons of an atom and are involved in chemical bonding. The number of valence electrons determines an element's reactivity and ability to form bonds. The arrangement and interactions of valence electrons ultimately determine the chemical properties of an element.
What characteristic does the alkali metals alkaline earth metals and the halogens have in common?
All alkali metals, alkaline earth metals, and halogens have a common valence electron configuration: alkali metals have 1 valence electron, alkaline earth metals have 2 valence electrons, and halogens have 7 valence electrons. This shared electron configuration influences their chemical properties, such as reactivity and bonding tendencies.
Is a metals luster is due to its valence electrons?
Most of the properties of a metal, including lustre, are due to the metallic bonding of the electrons.
How many valence electrons are in alkaline earth metals?
Alkaline earths have 2 valence electrons.

Do alkali metals contain 7 valence electrons?
No. Alkali metals have one valence electrons. Halogens have 7 valence electrons.
Why do all elements in the alkaline earth metals have similar properties?
2 valence electrons (apex)

How many valence electrons are in alkali metals?
one valence electrons
How many valence electrons are in alkaline earth metals?
Alkaline earths have 2 valence electrons.
What this element has five valence electrons shows properties of metals and non metals and has 33 protons in the nucleus of each atom?
Arsenic
What is the number of valence electrons in alkaline earth metals?
Alkaline earth metals have 2 valence electrons.
Are elements with very few valence electrons mostly non-metals?
Yes, elements with very few valence electrons are typically non-metals. Non-metals tend to have higher electronegativities, making them more likely to gain electrons to achieve a stable electron configuration. Elements with few valence electrons are more likely to gain electrons rather than lose them, leading to non-metallic properties.
How many valence electrons in alkaline earth metals?
The alkaline earth metals are those in the same group as calcium; they have two valence electrons.
