An atom is composed of protons (+1 charge), neutrons (0 charge), and electrons (−1 charge). An atom has a neutral charge (total charge =0). An atom loses several electrons to become an ion, and the result is a charge of +3. How can this ion become neutral? 3 protons and 3 electrons 3 protons and 3 electrons 3 neutrons 3 neutrons 3 protons 3 protons 3 electrons 3 electrons

i = 2 / - 5

step-by-step explanation:

evaluation of ( 2 - 4 ) ( p + q ) when p = 2 and q = 5 i, by putting values of p and q,                                                                    

step-by-step explanation:

the original amount doesn't ''re just looking for the time it takes for 1/2 of the substance to we have

(1/2) =)     take the ln   of both sides

ln (1/2)   = )   and we can write

ln(1/2) = ) lne     and lne   = 1     so we have

ln(1/2) = -.1092t     divide both sides by -.1092

t = ln(1/2)/-.1092 = about 6.347 days = about 6.3 days (rounded)
