What is mass?

Back

Mass is a measure of the amount of matter in an object, which does not change regardless of location, pressure, or gravity.

Front

What are the properties of metals?

Back

Metals are typically malleable, ductile, conductive, and have a high luster.

Front

What are protons?

Back

Protons are positively charged particles found in the nucleus of an atom.

Front

What do elements in the same group (family) have in common?

Back

Elements in the same group have the same number of valence electrons.

Front

What are physical properties?

Back

Physical properties are characteristics of a substance that can be observed or measured without changing its composition, such as color, size, shape, and density.

Front

What is weight?

Back

Weight is the force exerted by gravity on an object, which can change based on location.

Front

What is density?

Back

Density is the mass of an object divided by its volume, indicating how much matter is packed into a given space.

Front

What is the difference between malleable and ductile?

Back

Malleable refers to a material's ability to be hammered or pressed into shape without breaking, while ductile refers to a material's ability to be stretched into a wire.

Front

What are chemical properties?

Back

Chemical properties describe a substance's ability to undergo chemical changes, such as reactivity with other substances.

Front

What is the atomic structure?

Back

The atomic structure consists of protons and neutrons in the nucleus, surrounded by electrons in orbitals.
