What are two physical properties of metallic aluminum?
Two physical properties of metallic aluminum are its silver-white color and its high electrical conductivity.
Why is alluminium metal and carbon is not?
Aluminum is a metal because it has metallic properties such as being a good conductor of electricity and having a shiny appearance. Carbon, on the other hand, is a non-metal because it lacks these metallic properties and has a variety of physical forms including graphite and diamond.
What are physical properties of silver spoon?
A silver spoon has physical properties such as being shiny, metallic, malleable, and a good conductor of heat and electricity.
What happens to the physical properties of substances when they are at room temperature?
At room temperature, the physical properties of substances can change. For example, some substances may melt, freeze, evaporate, or condense. These changes can affect properties like color, texture, and state of matter.
Why are the properties of covalent compounds so diverse?
The diverse properties of covalent compounds arise from the varying strengths of the covalent bonds between atoms, different molecular structures, and the types of atoms involved. Factors like bond polarity, molecular shape, and intermolecular forces can all contribute to the wide range of physical and chemical properties exhibited by covalent compounds.
What type of bonding would be found between a metallic element and a covalent molecular element And do covalent bonds have physical or chemical properties and the same question for dispersion forces?
The bonding between a metallic element and a covalent molecular element is typically ionic in nature, where the metallic element donates electrons to the covalent molecule, resulting in electrostatic attraction. Covalent bonds exhibit distinct physical properties, such as low melting and boiling points, and they also influence chemical properties like reactivity and solubility. Dispersion forces, also known as London dispersion forces, are weak intermolecular forces arising from temporary dipoles in molecules; they primarily affect physical properties like boiling and melting points but do not typically influence chemical properties directly.
What are four physical properties shared by metallic elements?
Four physical properties shared by the metallic elements are that they are ductile, malleable, have good thermal conductivity, and have a metallic luster. They are also good conductors of electricity.
Why are the physical properties of the noble gases similar to those of covalent molecular substances?
The physical properties of noble gases are similar to those of covalent molecular substances because both have weak intermolecular forces between their particles. Noble gases exhibit London dispersion forces due to temporary dipoles, while covalent molecules share electrons through covalent bonds, resulting in weak forces of attraction between molecules.
Is lithium chemical or physical properties?
It has both. It is a metallic element.
How would changing the proportions substances in an alloy change its properties?
Changing the proportions of substances in an alloy will change the physical properties of that alloy. The differing substances will change the metallic structure of the crystals of the metal alloy, and this alters the ductility, durability, hardness, tensile strength, toughness and other characteristics we assess are regards alloys.

What is the difference in metallic and nonmetallic elements?
Differences exist in chemical and physical properties.

How physical properties and chemical properties are the same?
They both describe substances
