Shoot man tough luck

Answer: 1s²  2s²  2p⁶explanation: from the periodic table, we can note that the neutral fluorine  has 9 electrons (symbol is shown in the attached image)therefore, the configuration of neutral fluorine  is: 1s²  2s²  2p⁵now, f⁻  means that the neutral fluorine  gained one extra electron. this means that f⁻  has 10 electrons.the extra electron will occupy the 2p level to make it complete.the configuration now  is: 1s²  2s²  2p⁶comparing between both f and f⁻, we can note that f⁻  has now complete orbitals which means that it is more stable than f based on lewis postulatehope this : )

The chemical equation is ca(oh)2(s) + h2so4(aq) --> + h2o(l) in low concentrations it will stay in elucidation. at higher concentrations it will be precipitous.the oh- on the left responds with the h+ on the left to make hoh (h2o) as a produce. there's no oh- on the right hand side. so it should look like this:   ca2+ + 2oh- + 2h+ + so4^2- > caso4(s) + 2h2o(l)  hope this ! and mark me as brainliest if you dont mind : )
