The basics concept of chemistry | What is Atom? Characteristics of atoms? What are the types of chemical bond?
CHEMISTRY is the science and study of matter, including its properties, composition as well as reactivity. Chemistry relates to everything that can be sensed from the minutes elements to complex structures. The atom and molecules are the Basic units or components of chemistry. Atom: All matter consists of particles known as an atom. Atoms bond to each other to form elements, which contain only one kind of atom. Atoms of different elements form compounds, molecules, and objects. Model of the atom: An atom is a building block of matter that can not be broken apart using any chemical means. The 3 parts of the atoms are protons (positively charged), neutrons (neutral charged), and electrons (negatively charged). Proton and neutron form the NUCLEUS . Electrons are attracted to the protons in the nucleus but are moving quickly they fall toward orbit rather than stick to protons. The identity of an atom is determined by it's no. of protons. This is also called its atomic number. PARTS OF ...
