Ben Davis January 25, What happens to the atoms in your body after you die? Can you destroy an atom? Can protons be destroyed? Does splitting an atom destroy matter? Why is splitting an atom so dangerous? What would happen if you destroyed an atom? Can electrons be destroyed? How long does an atom last?

The semimetals can be found along the dividing line between the metals and the nonmetals. Elements are made up of atoms , the smallest particle that has any of the properties of the element.

John Dalton, in , proposed a modern theory of the atom based on the following assumptions. Atoms of different elements have different weights and different chemical properties. Atoms of different elements combine in simple whole numbers to form compounds. Atoms cannot be created or destroyed. When a compound decomposes, the atoms are recovered unchanged. Metals often react with nonmetals to form ionic compounds. These compounds are composed of positive and negative ions formed by adding or subtracting electrons from neutral atoms and molecules.

Nonmetals combine with each other to form covalent compounds , which exist as neutral molecules. The shorthand notation for a compound describes the number of atoms of each element, which is indicated by a subscript written after the symbol for the element. By convention, no subscript is written when a molecule contains only one atom of an element. Thus, water is H 2 O and carbon dioxide is CO 2.

Characteristics of Ionic and Covalent Compounds. They use the nutrients in their food to grow and repair their bodies—the atoms for new cells must come from somewhere. Any food that enters an animal's body must either leave its body or become part of it. No atoms are destroyed or created.

In any physical or chemical change, matter doesn't appear or disappear. Atoms created in the stars a very, very long time ago make up every living and nonliving thing on Earth—even you.

It's impossible to know how far and through what forms your atoms traveled to make you. And it's impossible to know where they will end up next.

For example, the carbon atom in coal becomes carbon dioxide when it is burned. The carbon atom changes from a solid structure to a gas but its mass does not change. Similarly, the law of conservation of energy states that the amount of energy is neither created nor destroyed. For example, when you roll a toy car down a ramp and it hits a wall, the energy is transferred from kinetic energy to potential energy.

Teach about the conservation of energy and mass with these classroom resources. Physical changes are reversible and do not produce a new substance.
