What are the chemical and physical properties of an alloy?
An alloy is a mixture of two or more elements, with at least one being a metal. Chemical properties of an alloy depend on the elements present and their proportions, affecting properties like corrosion resistance and reactivity. Physical properties include hardness, conductivity, and melting point, which also vary based on the alloy composition.
When two elements combine to form a compound do the elements keep the same properties they had as individuals or do they adapt with new properties as a compound?
They normally have new properties as a compound, example- sodium metal, extremely reactive, reacts violently with moisture; and chlorine gas, deadly poisonous, react together to form table salt-sodium chloride
How are two atoms of the same elements alike?
They have all the chemical, physical, nuclear properties identical. This is not the case for isotopes.
Is a compound a physical mixture of a simpler substance?
No, a compound is not a physical mixture; it is a chemical combination of two or more elements that are bonded together in fixed proportions. Unlike a mixture, where the individual components retain their properties and can be separated by physical means, the elements in a compound undergo a chemical change and lose their individual properties. Compounds have distinct characteristics that differ from those of their constituent elements.
Is it true that an alloy is a mixture of elements that has metallic properties?
Yes, that is true. An alloy is a solid solution or a mixture of two or more elements, at least one of which is a metal. Alloys often display metallic properties such as conductivity, malleability, and ductility.
What are two physical properties of metal?
Density Boiling point
Why is magnesium a metal?
magnesium is not a metal but a reactive metal. scientists have divided all elements into two types of category: metals and non-metals to classify them as they have different chemical and physical properties. magnesium has properties of a metal so it is a metal.

Are iron and sulfur different?
Yes, iron and sulfur are different elements. Iron is a metal with the symbol Fe and atomic number 26, while sulfur is a non-metal with the symbol S and atomic number 16. They have different physical and chemical properties.
What two elements in the periodic table have similar properties?
element in a group exibhit more or less same properties some of them have more things and some have less as they are dependent on the valency in the outermst shell of the elctrons so that they acn become reactive ,metal non metals etc
How are two atoms of the same elements alike?

What type of solution is an alloy?
an alloy is a solid solution and a solution usually refers to solid or gas
The difference between aluminum and iron?
They are two different elements composed of two different types of atom. They have different chemical and physical properties.
What are two physical characteristics of group 15?
The elements of group 15 vary widely in the physical properties, from gaseous nitrogen (N) to non-metal solid phosphorus (P) to metalloid antimony (Sb) to soft metal bismuth (Bi). However, all react similarly in chemical reactions with three valence electrons.

Is argon and potassium the same?
No, argon and potassium are not the same. They are two different elements on the periodic table with different physical and chemical properties. Argon is a noble gas with atomic number 18, while potassium is an alkali metal with atomic number 19.
