Atomic Structure Quiz Questions And Answers
(127).jpg "Atomic Structure Quiz Questions And Answers - Quiz")
Would you be able to explain atomic structure? Then, take up this quiz with interactive questions and answers and see for yourself. An atom structure consists of a positively charged nucleus surrounded and neutralized by negatively charged electrons circling in orbits at varying distances from the nucleus. The arrangement of electrons contrasts with various chemical elements. The number of electrons is equivalent to the number of protons. You may need to know this information for your exam, and the below quiz can come to your rescue. Let's get started.
