What is molecule in simple?
What is molecule in simple?
The smallest particle of a substance that has all of the physical and chemical properties of that substance. Molecules are made up of one or more atoms.
What is atom in simple words?
An atom is a particle of matter that uniquely defines achemical element. An atom consists of a central nucleus that is usually surrounded by one or more electrons. Each electron is negatively charged. The nucleus is positively charged, and contains one or more relatively heavy particles known as protons and neutrons.
What is molecule class 9th?
A group of two or more than two atoms of the same or different elements that are chemically bonded together is called a molecule.
What are simple and complex molecules?
Simple molecules are made up to one or two atoms of the same element eg., oxygen, and water. Complex molecules are made up of more than two atoms of the same or different elements eg., calcium carbonate,. They tend to have stronger bonds than simple elements.
How do molecules form?
When two or more atoms chemically bond together, they form a molecule. Sometimes the atoms are all from the same element. For example, when three oxygen atoms bond together, they form a molecule of ozone (O3). If a molecule forms from atoms of two or more different elements, we call it a compound.
What is the difference atoms and molecules?
Atoms are single neutral particles. Molecules are neutral particles made of two or more atoms bonded together.
What is a molecule class 6?
Answer: Solution : The smallest unit of matter which can exist independently is called a molecule. Example – Oxygen molecule O 2 O_2 O2.
What is a complex molecule?
In astronomy, complex organic molecules are molecules with multiple carbon atoms such as benzene and acetic acid. These molecules have been detected in interstellar space with radio telescopes. In chemistry, “complex organic molecules” refer to polymer-like molecules such as proteins.
What is the difference between simple and extended molecules?
Examples of simple molecules could include ammonia and methanol. Examples of extended structures could include sodium chloride or diamonds. Examples of molecular-level models could include drawings, 3D ball and stick structures, or computer representations showing different molecules with different types of atoms.]
What is a molecule explain to kids?
A molecule is two or more atoms joined (or “bonded”) tightly together. The number and kinds of atoms in a molecule, and the way they are arranged, determine what substance it makes. For example, a molecule made of two oxygen atoms joined to one carbon atom forms carbon dioxide, a colorless gas.
How do molecules work?
Molecules are held together by shared electron pairs, or covalent bonds. Such bonds are directional, meaning that the atoms adopt specific positions relative to one another so as to maximize the bond strengths. As a result, each molecule has a definite, fairly rigid structure, or spatial distribution of its atoms.
What is atom and molecule Short answer?
Define atom. Answer: The smallest particle of matter, which can take part in a chemical reaction is called atom. Question 5. Define molecule. Answer: The smallest particle of an element or compound which can exist independently is called molecule.
