Chemistry is the science and study of matter, including its properties, composition as well as reactivity. ... The atom and molecules are the basic unit or components of Chemistry. The study of chemists is always interested in identifying and knowing how the chemical transformation occurs.
<span>Carbon dioxide diffuses 20 times faster than oxygen gas
It is estimated, however, that the diffusing capacity of carbon dioxide is from 400 ml to 450 ml per minute under resting conditions and the diffusion capacity for oxygen under resting conditions is 21 ml per minute.</span>
Answer:
Atom then element
Explanation:
Scientists once thought the most fundamental building block of matter was a particle called the atom. Now we know that the atom is made of many smaller pieces, known as subatomic particles. Every atom contains a central core called the nucleus, made of particles called protons and neutrons.
An element is a pure substance and is made of only one type of atom; it cannot be broken down into a simpler substance.
