are atoms ever at rest?

They are always at rest with respect to some reference frame. To make a measurement on an electron you can choose it's state of motion by choosing the appropriate reference frame to measure it in.

No, atoms are not living things. Whether something is alive depends on its ability to do things like grow, respire and reproduce. These are obviously only things that complicated structures can do, not atoms.

Atoms and molecules in liquids and gases are bouncing and floating around, free to move where they want. The molecules in a solid are stuck in a specific structure or arrangement of atoms. The atoms still vibrate and the electrons fly around in their orbitals, but the entire atom will not change its position.

Dalton theorized that all matter is made of atoms. Atoms are too small to see, “uncuttable,” and indestructible. All atoms of a given element are exactly alike and atoms of different elements are different. In 1897, the English scientist named J.J.

In the same way that a large solid holds its shape, the atoms inside of a solid are not allowed to move around too much. Atoms and molecules in liquids and gases are bouncing and floating around, free to move where they want. The molecules in a solid are stuck in a specific structure or arrangement of atoms.

The atom itself is neither created nor destroyed but cycles among chemical compounds. Ecologists can apply the law of conservation of mass to the analysis of elemental cycles by conducting a mass balance.

Inside the Atom All matter is made up of atoms. ... These shells are actually different energy levels and within the energy levels, the electrons orbit the nucleus of the atom. The ground state of an electron, the energy level it normally occupies, is the state of lowest energy for that electron.

Atoms represent the smallest pieces of matter with constant properties, and are referred to as the basic unit of matter. However, scientists have discovered that atoms are not the smallest particles in nature. Despite their minuscule size, a number of much smaller particles exist, known as subatomic particles.

Atomic particles Protons and neutrons are heavier than electrons and reside in the nucleus at the center of the atom.

Atoms are filled with electrons. It's true that a large percentage of the atom's mass is concentrated in its tiny nucleus, but that does not imply that the rest of the atom is empty. Rather, it implies that the rest of the atom has relatively low density.

Atoms are the basic building blocks of ordinary matter. Atoms can join together to form molecules, which in turn form most of the objects around you. ... A particular atom will have the same number of protons and electrons and most atoms have at least as many neutrons as protons.

Atoms are not living things; they do not need food, water, and air; and they do not reproduce themselves. Cells are alive. Cells are bigger than atoms. ... Just as atoms have smaller parts called protons, neutrons, and electrons, cells have smaller parts, too.

An atom, at the most basic level, consists of a positively charge atomic nucleus that's extremely tiny in volume. For every proton in the atomic nucleus, there's an equal and opposite quantum of charge that orbits around it, creating an overall neutral system: the electron.

Hot things move quickly, cold things very slowly. If atoms come to a complete stop, they are at absolute zero. Space is just above that, at an average temperature of 2.7 Kelvin (about minus 455 degrees Fahrenheit).

The atom is the basic building block for all matter in the universe. Atoms are extremely small and are made up of a few even smaller particles. The basic particles that make up an atom are electrons, protons, and neutrons. Atoms fit together with other atoms to make up matter.

All matter is made of atoms. ... Atoms cannot be created nor destroyed, and they are indestructible; they cannot be broken into smaller parts. This was based on the Law of Conservation of Mass. It was later learned that atoms can break into smaller parts.

A stable atom is an atom that has enough binding energy to hold the nucleus together permanently. An unstable atom does not have enough binding energy to hold the nucleus together permanently and is called a radioactive atom.
