Best Learning Modules and CBSE Science Question Paper 2020
 
Chemistry is the study of matter and CBSE Science question papers for 2020 are very important to understand the interactions between different types of matter and energy and the fundamental building block of matter is the atom. An atom consists of three main parts: protons, neutrons, and electrons. Protons have a positive electrical charge. Neutrons have no electrical charge. Electrons have a negative electrical charge. Protons and neutrons are found together in the nucleus of the atom. Electrons circle around the nucleus. The matter has mass and takes up space. Atoms are basic building blocks of matter, and cannot be chemically subdivided by simple means. The word atom is derived from the Greek word atom which means indivisible as the Greeks concluded that matter could be broken down into particles to small to be seen. These particles were called atoms. Atoms are composed of three types of particles: protons, neutrons, and electron and protons and neutrons are responsible for most of the atomic mass. Chemical bonding and chemical reactions occur due to the electrons around atoms. An atom with too many or too few electrons is unstable and may bond with another atom to either share or essentially donate electrons. To study The Structure of Atom in detail, you need to identify each of the particles present and thus work on how they must have constituted into molecules to form different types of elements. When these elements are mixed together, they form a substance which ultimately supports the ecosystem in one way or the other. Chemical reactions involve interactions between the electrons of one atom and the electrons of another atom. Atoms which have different amounts of electrons and protons have a positive or negative electrical charge and are called ions. When atoms bond together, they can make larger building blocks of matter called molecules.
