How many valence electrons dose a bromine anion contain?
A bromine anion (Br-) contains 8 valence electrons. Bromine is in group 7A of the periodic table and has 7 valence electrons. When it gains an extra electron to form an anion, it now has a total of 8 valence electrons.
What dose Fe has 26 protons how many neutrons or electrons dose it have?
Iron has 26 electrons; the number of neutrons is different for each isotope (number of neutrons = mass number - 26).
How many electrons dose manganese have?

How many electrons dose a nitrogen atom have?
8 electrons which equals the atomic number
How many valance electrons dose a sodium atom have?
Since sodium has atomic number 11, its electronic configuration is untill 3s1. This means the valence shell has 1 electron, so it has 1 valence electron.
How many more valence electrons dose sodium need?
Sodium has one valence electron in its outermost shell (the third electron shell). To achieve a stable electron configuration, similar to that of the nearest noble gas (neon), sodium needs to lose this single valence electron rather than gain more. Therefore, sodium does not need additional valence electrons; it only needs to lose its one valence electron to achieve stability.
How many valence electrons dose lead have?
i think its 4 though ive herd it to be 6 by some, ur best bet is to use the periodic table.
