Electrons exist in energy levels or shells around the nucleus, and each shell can hold a specific number of electrons. Example of an atom: Atomic Number: 6 (Carbon) Protons: 6 Neutrons: 6 Electrons: 6 (2 in the first shell, 4 in the second shell) 反馈 收藏 有用 解析 免费查看答案及...
The number of protons in an atom equals the number ofelectrons. This is necessary to balance the charge of an atom, and to increase its stability... Learn more about this topic: Atom | Definition, Composition & Examples from Chapter 2/ Lesson 1 266...
The atomic number represents the number of protons in an atom's nucleus. In an uncharged atom, the number of protons is always equal to the number of electrons. For example, carbon atoms include six protons and six electrons, so carbon's atomic number is 6. ...
What determines the atomic number of an atom? A. Number of electrons in the other shell. B. Mass of the atom. C. The number of neutrons. D. The number of protons. E. The number of protons plus neutrons. The ___ is the ...
<p>To determine the maximum number of electrons in the M-shell, we can use the general formula for calculating the number of electrons in a shell, which is given by:</p><p><span class="mjx-chtml MJXc-display" style="text-align: center;"><span class="mjx-
2\. Above the symbol is the atomic number (Z) which is equal to the number of protons in the nucleus and the number of electrons in the electron cloud (given that the atom is neutral). For carbon Z=6. 3\. Below the symbol is the atomic mass. While this number is a weighted aver...
Each element on the periodic table has a different atomic number. Currently, the atomic numbers of known elements range from 1 to 118. The nucleus of an atom contains protons and neutrons. An atom's electrons are found in orbitals around the nucleus. The atomic number definition is based on...
Each atom in a redox reaction is assigned an oxidation number to understand its ability to donate, accept, or share electrons. It shows the total number of electrons that have been removed from or added to an element to get to its present state. For example, in Fe2O3, the oxidation ...
