Molecules, on the other hand, are formed when two or more atoms chemically combine. These atoms are held together by chemical bonds, which can be covalent, ionic, or metallic in nature. Covalent bonds involve the sharing of electrons between atoms, creating stable molecular structures. Ionic bon...

CHEMICAL BONDS When two or more elements come together, they form a compound. Compounds are held together by forces called chemical bonds. Atoms can form chemical bonds by sharing electrons or by transferring electrons from one atom to another. Types of Bonds When a compound is formed through t...
Atoms can neither be created nor be destroyed Atoms of same elements are similar. Atoms of different elements are different. Atoms combine in the ratio of small whole numbers to form compounds. The relative number and kinds of atoms are constant in a given compound. What is an Atom ...
Atoms combine in a ratio of small whole numbers to form compounds. The matter is anything and everything in our surrounding. It has basic structural and fundamental units. Let us examine the concept of matter with an example. Taking a storybook into consideration and dividing its structure. The...

Elements also have specific chemical reactivity, the ability to combine and to chemically bond with each other.In the periodic table, shown in Figure 3, the elements are organized and displayed according to their atomic number and are arranged in a series of rows and columns based on shared ...
Chemical bonds cause two nuclei of different atoms to combine as one. True or false? Polar bonds are caused by the bonding pair of electrons being attracted more to one atom than the other. True or false? When forming compounds, single atoms can be used. Cov...
