Metals conduct electricity.
Metals ionise [lose one or more electrons] to form positively charged ions - cations.
Most metals share properties such as high electrical conductivity, high thermal conductivity, malleability, ductility, and shiny appearance. They also tend to form cations by losing electrons in chemical reactions.
They have high ionization energy and high electronegativity.
The most of the chemical elements are metals. Most are transition metals (located in the middle of the Periodic Table).
The alkali metals (Group 1) and the alkaline earth metals (Group 2) are most similar in chemical properties due to both groups having similar metallic properties, reactivity, and ability to form cations with a +1 or +2 charge.
Strontium has chemical properties most like calcium as they belong to the same group (group 2) in the periodic table, known as the alkaline earth metals. They both share similar reactivity, solubility, and ability to form white precipitates with sulfate ions.

The chemical properties of calcium are most similar to the chemical properties of magnesium and strontium, as they all belong to the same group in the periodic table (Group 2 or alkaline earth metals). These elements share similar reactivity, ionization tendencies, and ability to form ionic compounds with similar characteristics.
Metals in the same group on the periodic table tend to have similar properties due to their shared number of valence electrons. Thus, metals in groups 1 (alkali metals) and 2 (alkaline earth metals) would have more similar properties compared to metals in different groups.
Most elements are classified as metals, nonmetals, or metalloids based on their physical and chemical properties. Metals are typically shiny, malleable, and good conductors of heat and electricity. Nonmetals are generally poor conductors and can be gases or brittle solids. Metalloids have properties of both metals and nonmetals.
Chemical elements can be divided into metals and non-metals. Metals typically have properties like luster, conductivity, and malleability, while non-metals are generally less shiny, poor conductors, and more brittle.
Examples: resistance to corrosion, valence, Pauling electronegativity.

Density
These properties are: luster, malleability, ductility, conductivity, hardness, resilience, elasticity, shear modulus, etc.
Iodine has the most similar chemical properties to bromine because they are both halogens belonging to the same group on the periodic table. They exhibit similar reactivity and form similar compounds due to their shared electron configuration.
