WebStudy with Quizlet and memorize flashcards containing terms like 1. How many electrons must be present before an atom has a second shell? a. 2 b.3 c.8 d.11 2. Select the statement that best describes the movement of electrons under normal conditions. a. Electrons do not move within their shells. b. Electrons can move in any direction within … WebWhen we look at an atom, we find that it has the same about of protons as it does electrons. So, if we look at oxygen, we see that its atomic number is 8, meaning that it has 8 protons. We can also assume that it has 8 electrons. So, oxygen has eight positive particles plus eight negative particles. Think of this as 8+ (-8) or 8-8.

Web19 jan. 2024 · An atom typically consists of electrons, protons, and neutrons. Electrons are negatively charged and participate in bonding to stabilize the atom. Conversely, protons are positively charged and balance the charge of the atom. In addition, their positive charge attracts the negatively charged electrons. What role do neutrons play in an atom? WebAn atom is composed of two regions: the nucleus, which is in the center of the atom and contains protons and neutrons, and the outer region of the atom, which holds its electrons in orbit around the nucleus. Protons and neutrons have approximately the same mass, about 1.67 × 10-24 grams, which scientists define as one atomic mass unit (amu) or ...
