Matter is made of atoms that have positive centers of neutrons and protons surrounded by a cloud of negatively charged electrons. This statement is—
Answer (1)
Atoms are the building blocks of everything, from your pencil to your dog to the air you breathe. The center of an atom, called the nucleus, is where you find protons and neutrons. Protons have a positive charge, like the north pole of a magnet. Neutrons are neutral – they don't have a charge at all. Electrons whiz around the nucleus in a cloud, and they carry a negative charge, like the south pole of a magnet. So, the statement is close, but it says "positive centers of neutrons and protons." Here's where we need to be careful! Neutrons don't have a charge, so the positive center is just the protons. That's why we call the nucleus the "positive center" – it's because of those protons!
