Atoms are the building blocks of all matter. Carbon is the most versatile element that bonds with itself and other elements. Living things need carbon in order to grow, live, and reproduce. Two or more elements joined chemically are known as compounds. Sodium and chlorine are poisonous alone, but when combined they form table salt. Overall, classes of matter is important because without matter, the earth, the universe, and all things we know and love would not exist.

What is the difference between heterogenous and homogeneous mixtures?

# data[].attributes.body
Mixtures are defined as a combination of two or more substances that are physically combined. Heterogeneous mixtures appear differently throughout and can be easily separated. Salads, Chex Mix, and stew are examples of heterogeneous mixtures. Homogeneous mixtures, also known as solutions, appear uniform throughout. Kool-Aid, salt water, and lemonade are examples of homogeneous mixtures.

How is the periodic table of elements organized?

# data[].attributes.body
The periodic table of elements was discovered by Mendeleev. He originally arranged the elements by atomic mass, but the modern table is arranged by atomic number. There are 18 groups or families (columns) and 7 periods (rows). There are three distinct types of elements: metals, nonmetals, and metalloids. Ninety-two elements are found naturally on Earth and the other elements were created in a lab.

Particles are the building blocks of atoms. The nucleus is made up of protons and neutrons. The electrons carry negative charges and combine with other atoms to form new substances.
