No, Mendeleev grouped the elements by atomic mass and chemical properties to create the periodic table. While there may be some correlation between element density and position on the periodic table, density was not the primary factor Mendeleev used for organization.
According to Chemists, the elements of sodium and chlorine belong to the same atomic family as well as carbon and lead.
Most don't, but a few do. Na and K come immediately to mind ie the Alkali Metals.
Yes, elements can have similar properties if they are in the same chemical group or have the same number of valence electrons. This can lead to similarities in their chemical reactivity and physical characteristics.
The density of elements generally increases from left to right across a period in the periodic table and decreases down a group. This trend is due to the increasing atomic mass and decreasing atomic volume of elements. Higher density elements tend to have higher melting and boiling points, as well as greater hardness and strength.

Density is a property of a substance, not an object. It is the mass of a substance per unit volume. The density of a substance remains the same regardless of the size or shape of the object made from it.
uh pretty sure everything has some amount of density to it.
Elements in the same group have the same number of valence electrons.
Hydrogen with 0.09 density
Density is simply the mass divided by volume. This means that it is the amount of the substance in a specific unit of space. Because a pure substance indicates that it is exactly that, a substance made of a specific combination of elements, it will always have the same density because those elements can only take one form in order for it to be pure.
The moon's average density is about the same as the density of mantle of the Earth.
Iridium is the elemento with the highest density
The small amounts of different elements in a mineral can change its color, hardness, and other physical properties.
get larger
The density of iodine at room temperature is 4,933 g/cm3. This is not a high density.
Density helps to identify the elements on the pedriatic table
