Answer is: group 17 on the periodic table.
Group 17 (halogens) elements are: fluorine (F), chlorine (Cl), bromine (Br) and iodine (I).
They are very reactive and easily form many compounds.
Fluorine and chlorine are in gaseous state, bromine is liquid and iodine is in solid state in room temperature.
Halogens need to gain one electron to have electron cofiguration like next to it noble gas.
For example, fluorine has 9 electrons and it gain easily one electron in chemical reaction to have electron configuration like noble gas neon (Ne) with 10 electrons.
Answer:
Possible lowest volume = 0.19 cm
Possible highest volume = 0.21 cm
Explanation:
given data
volumetric pipette uncertainty = 0.01 cm³
total volume = 0.20 cm³
solution
we will get here Possible lowest and highest volume that is express as
Possible lowest volume = total volume - uncertainty .....................1
Possible highest volume = total volume + uncertainty ....................2
put here value in both equation and we get
Possible lowest volume = 0.20 cm - 0.01 cm
Possible lowest volume = 0.19 cm
and
Possible highest volume = 0.20 cm + 0.01 cm
Possible highest volume = 0.21 cm

i hope that helps!
Answer:
Explanation:
the element is sulphur so it gains electrons, since it is not a metal
