The basic unit of matter is the atom. It is the smallest particle of an element which can take part in chemical reactions and may or may not exist separately. It consists of sub-atomic particles, i.e., protons, neutrons and electrons. Click to see full answer.

Elements and Atoms

An element is a pure substance. It cannot be broken down into other types of substances. Each element is made up of just one type of atom.

Structure of an Atom

An atom is the smallest particle of an element that still has the properties of that element. Every substance is composed of atoms. Atoms are extremely small, typically about a ten-billionth of a meter in diameter. However, atoms do not have well-defined boundaries, as suggested by the atomic model shown in figure (PageIndex{2}). An atom is composed of my subatomic particles. We will only discuss protons, neutron, and electrons.

If the number of protons and electrons in an atom are equal, then an atom is electrically neutral because the positive and negative charges cancel out. If an atom has more or fewer electrons than protons, then it has an overall negative or positive charge, respectively, and it is called an ion.

The negatively charged electrons of an atom are attracted to the positively charged protons in the nucleus by a force called electromagnetic force, for which opposite charges attract. Electromagnetic force between protons in the nucleus causes these subatomic particles to repel each other because they have the same charge. However, the protons and neutrons in the nucleus are attracted to each other by a different force, called nuclear force, which is usually stronger than the electromagnetic force repelling the positively charged protons from each other.

Periodic Table of the Elements

There are almost 120 known elements. As you can see in the Periodic Table of the Elements shown in Figure (PageIndex{3}), the majority of elements are metals. Examples of metals are iron (Fe) and copper (Cu). Metals are shiny and good conductors of electricity and heat. Nonmetal elements are far fewer in number. They include hydrogen (H) and oxygen (O). They lack the properties of metals. The element most important to life is Carbon (C). Find carbon in the table. What type of element is it, metal or nonmetal?

Hereof, what are the particles that take part in a chemical reaction?

Electrons are the negatively charged particles of an atom that are involved in chemical reactions.

Likewise, is an atom the smallest part of an element? Advanced systemcare 12 pro (lifetime activation). The protons and neutrons are found in the center of the atom, called the atomic nucleus, and the electrons move around the center of the nucleus in regions known as electron clouds. Definition List: atom - An atom is the smallest unit of an element that still has all the properties of that substance.

Besides, what is the smallest part of a compound called?

Answer and Explanation:The smallest particle of a compound is called a molecule. A compound is made up of two or more different chemical elements, e.g., a water molecule

Does atoms take part in chemical reaction?

The Smallest Particle Of An Element To Still Be That Element Is The

In a chemical reaction, only the atoms present in the reactants can end up in the products. No new atoms are created, and no atoms are destroyed. In a chemical reaction, reactants contact each other, bonds between atoms in the reactants are broken, and atoms rearrange and form new bonds to make the products.
