Parts Of An Atom Worksheet

What are the Parts of an Atom?

Atom is the almost basic unit of matter. Information technology has a dense nucleus with a cloud of negatively charged electrons surrounding it. Here are the parts of an Atom: Electron; it is a subatomic particle with a negative electrical charge. The mass of an electron is and so small-scale that it is generally not even considered. Nucleus; the dense center of an atom containing neutrons and protons. Neutron; information technology is a subatomic particle within the nucleus of an atom that has a neutral charge. Proton; a subatomic particle inside the nucleus of an atom with a positive charge. All three subatomic particles have mass. Protons and neutrons accept what is considered ane atomic mass unit of measurement, only the electron has a lot less mass. In fact it has one-thousandths an diminutive unit. Because of their contrary charges electrons and protons are attracted to one some other holding the nucleus together somewhat. Because of the fifty-fifty charges, atoms are electrically neutral. If an atom looses or gains an electron, it becomes an ion. Due to the uneven charges, they are considered ions and have an overall negative or positive charge.

Using the Periodic Table of Elements

Use the Periodic Table of Elements and your knowledge of chemistry to complete the blanks for each chemical element. Round the diminutive mass to the nearest whole number.
