Answers
Matter is everything around you. Atoms and compounds are all made of very small parts of matter. Those atoms go on to build the things you see and touch every day. Matter is defined as anything that has mass and takes up space (it has volume).
Answer:
A common or traditional definition of matter is "anything that has mass and volume (occupies space)". For example, a car would be said to be made of matter, as it has mass and volume (occupies space). The observation that matter occupies space goes back to antiquity.
The story of particle physics goes back 2000 years to the Greeks; and Isaac Newton thought that matter was made up of particles in the 17th century. However, it was John Dalton who formally stated in 1802 that everything is made from tiny atoms.
At that time, the atom was thought to be 'the building block of matter. ... In 1911, a scientist named Ernest Rutherford discovered that atoms are really made of a positively charged center called the nucleus orbited by negatively charged particles called electrons electrons.
