Common Shortcut Keys. It's hard to remember all the shortcut keys out there. But luckily, most programs adopt conventions (like Ctrl+S, which always saves what you're working on). Even better, programmers typically choose shortcut keys mnemonically (again, like Ctrl+S for Save) to make it easier for us to remember.
This means, that the number of electrons present in an chlorine atom is 17. The energy shells of an atom are in the order K, L, M â¦ So the electronic configuration of chlorine atom is: K, L, M = 2, 8, 7. Valence electrons are the number of electrons present in the outermost shell of an atom. The last shell of a chlorine atom has 7 electrons in it. Therefore, there are 7 valence electrons in an chlorine atom. Here is a video which gives a quick discussion of how to determine how many valence electrons atoms of different elements have.
Chlorine is an element in the periodic table, which is denoted by Cl. It is a halogen (17 th group) in the 3 rd period of the periodic table. The atomic number of chlorine is 17; thus, it has seventeen protons and seventeen electrons. Its electron configuration is written as 1 s 2 2 s 2 2 p 6 3s 2 3p 5.Since the p sub level should have 6 electrons to obtain the Argon noble gas electron configuration, chlorine is able to attract an electron.hlorine vs Chloride. The elements in the periodic table are not stable except the noble gases. Therefore, elements try to react with other elements, to gain the noble gas electron configuration to achieve stability.
