WebSo that means that sodium has one valence electron. And that's very convenient, because sodium is found in group one. And so we can say that for main groups, if you want to figure out how many valence electrons you have, it's just equal to the group number. So the group number is equal to the number of valence electrons. WebElement Bromine (Br), Group 17, Atomic Number 35, p-block, Mass 79.904.

How many valence electrons does barium gain or lose?
WebThe number of electrons in an electrically-neutral atom is the same as the number of protons in the nucleus. Therefore, the number of electrons in neutral atom of Bromine is 35. Each electron is influenced by the electric fields produced by the positive nuclear charge and the other (Z – 1) negative electrons in the atom. WebJan 30, 2024 · Lithium has three electrons: two go to K shell and; the remaining one goes to the L shell. Its electronic configuration is K(2), L(1) Fluorine has nine electrons: two go to K shell and; the remaining seven go to the L shell. Its electronic configuration is K(2), L(7). Note that L can have 8 electrons. Aluminum has thirteen electrons: dhhr beckley office

WebAnd this is explained if we look at fluorine's valence shell (the second shell) electron configuration: 2s^ (2)2p^ (5). The second electron shell holds a maximum of 8 electrons and 8 electron would be considered a filled valence shell and would therefore be stable and unreactive. But fluorine has 7 valence electrons, 1 away from being filled. http://www.chem4kids.com/files/elements/035_shells.html dhhr change of address
