Melals have free electrons. Hence metals react easily by giving electrons.
Metals typically have an abundance of free electrons due to their atomic structure, which allows for the delocalization of electrons within the material. This gives metals their characteristic properties such as high electrical conductivity.
Low ionization energies are typically characteristic of atoms that have large atomic size and few protons in their nucleus, such as alkali metals and alkaline earth metals. These atoms have loosely bound electrons that require less energy to remove.
One characteristic of non-metals is that they are generally gaseous at room temperature. Non-metals will also typically bond with metals easily.
"Dense" is a property that can describe both metals and non-metals. Metals in general tend to be denser than non-metals due to their atomic structure, but there are exceptions. It's important to consider the specific element in question when determining its density.
Atomic emission spectrometry is limited to alkali metals.
Metals conduct electricity; non-metals do not.
No the opposite. It is a characteristic of metals that they have very little or no odor.
they are harder than alkali metals
they are harder than alkali metals
All metals except alloys of metals are elements, but not all elements are metals.
Brittleness is not a characteristic of most metals. Metals are usually ductile and malleable, meaning they can be bent and shaped without breaking. However, some metals, such as cast iron, can exhibit brittleness under certain conditions.
The chemical reactivity of alkali metals increase when the atomic number increase.
