What comes first atom or matter?
Matter can be described as anything having mass and volume. Matter can be better defined, though, by separating it into its simplest parts. Since the atom is the basic unit of matter, we will start there. A group of similar atoms is called an element.
What is matter choose the best answer *?
Matter is anything that has mass and takes up space. Matter is anything that reflects light. Matter is anything that absorbs light. What do water vapor, liquid water, and ice have in common?

A plasma is an electrically charged gas. In a plasma, some electrons have been stripped away from their atoms. Because the particles (electrons and ions) in a plasma have an electrical charge, the motions and behaviors of plasmas are affected by electrical and magnetic fields.
Are all elements single atoms?
2.8. Elements can be made of one atom, like He, or be elemental molecules, such as hydrogen (H2), oxygen (O2), chlorine (Cl2), ozone (O3), and sulfur (S8). Atoms are not drawn to scale. Some elements are monatomic, meaning they are made of a single (mon-) atom (-atomic) in their molecular form.
What created atoms?
Atoms were created after the Big Bang 13.7 billion years ago. As the hot, dense new universe cooled, conditions became suitable for quarks and electrons to form. Quarks came together to form protons and neutrons, and these particles combined into nuclei.
