the group 7a alements are called the halogens their atom have seven electron in their valence shell and have a strong tendency to gain one more electron. they are active nonmetal and are present on nature only in the form of their compounds. as shown in figure 2.12 the halogens consist of diatomic molecule. f,cl,br,i) flourine,a pale of pellow,poisonous gas is the most reactive of all the element it corrodes even platinum, a metal that with stands most other chemicals. because it is so reactive
ang pangkat ng 7a na mga elemento ay tinatawag na mga halogens na kanilang atom ay may pitong elektron sa kanilang valence shell at may isang malakas na pagkahilig upang makakuha ng isa pang elektron. ang mga ito ay aktibo na hindi pang-katawan at naroroon sa likas na katangian lamang sa anyo ng kanilang mga compound. tulad ng ipinapakita sa figure 2.12 ang mga halogens ay binubuo ng diatomic molekula. f, cl, br, i) flourine, isang maputla ng kape, nakalalasong gas ang pinaka-reaktibo ng lahat ng elemento na kinukumpirma nito kahit ang platinum, isang metal na may pinakamaraming iba pang mga kemikal. dahil ito ay sobrang reaktibo
