Exploring Atoms, Compounds, and Mixtures

What are the three main parts of an atom?

• Protons, Neutrons, Electrons

• Electrons, Neutrons, Quarks

• Protons, Photons, Neutrons

• Protons, Neutrons, Positrons

How do neutrons differ from protons?

• Neutrons are found outside the nucleus, while protons are inside the nucleus.

• Neutrons have a mass greater than protons.

• Neutrons are positively charged, while protons are neutral particles.

• Neutrons are neutral particles, while protons are positively charged.

What is the nucleus of an atom made of?

• Protons and neutrons

• Photons and neutrinos

• Electrons and positrons

• Quarks and leptons

Define a compound in terms of its composition.

• A compound is a substance that cannot be broken down into simpler substances by chemical means.

• A compound consists of only one type of element in any ratio.

• A compound is a substance made up of two or more elements chemically combined

• A compound is a mixture of different substances that can be separated easily.

How can you identify a compound from its chemical formula?

• By analyzing the elements and their ratios in the formula.

• By determining the color of the compound.

• By observing the compound's physical state at room temperature.

• By measuring the boiling point of the compound.

What is a mixture?

• A mixture is a single substance with uniform composition.

• A mixture is a solution that cannot be separated by physical means.

• A mixture is a chemical reaction between two substances.

• A mixture is a combination of two or more substances that are not chemically bonded.

What are the two main types of mixtures?

• Solid and liquid mixtures

• Natural and artificial mixtures

• Homogeneous and heterogeneous mixtures

• Simple and complex mixtures

Give an example of a homogeneous mixture.

• Saltwater

• Air

• Oil

• Sand

What is a heterogeneous mixture?

• A heterogeneous mixture is a mixture where the components are not uniformly distributed and can be easily distinguished.

• A heterogeneous mixture is a pure substance with a fixed composition.

• A heterogeneous mixture cannot be separated into its components.

• A homogeneous mixture is a mixture where the components are uniformly distributed.

What is the process of separating a mixture called?

• Chemical reaction

• Separation process

• Filtration method

• Mixture analysis
