No. You can live without aluminum or helium, but you cannot live without iodine.
is it so? Bromine is more electronegetive than Iodine
No, nitrogen is more electronegative than iodine. Electronegativity of nitrogen= 3.04 Electronegativity of Iodine = 2.66
Helium has more mass than hydrogen. Helium is composed of two protons and two neutrons, while hydrogen is a single proton.
the aluminium wire was as powerful as a king.
Air has many more different substances than helium, which is a single substance. Outside air contains helium.
The world's atmosphere includes Nitrogen, Oxygen, Hydrogen, Carbon Dioxide, Helium, Argon, Radon, Fluorine, Chlorine, Bromine, Iodine, Neon, and more.
Helium is a lighter-than-air gas, so it's handy for filling balloons with. Probably more "important" than that though is the fact that helium is not very reactive (it is chemically inert), and in particular it is not flammable, unlike hydrogen.
Iodine is not a soap. It doesn't clean the skin. It is merely one more barrier for germs to penetrate.
iodine has more protons because it has 53 protons and sulfur only has 16. glad to help

The beaker is more concentrated in iodine because it contains a higher amount of iodine compared to the baggie.
No, Sulfur has 16 protons, and Iodine has 53. So that means that Iodine has more protons than Sulfur.
Iodine has more protons than sulfur. Iodine has 53 protons in its nucleus, while sulfur has 16 protons.
No, nitrogen is more electronegative than iodine. Electronegativity of nitrogen= 3.04 Electronegativity of Iodine = 2.66
Iodine act as modrant for crystal violet and helps its attachement more firmly.
At that time aluminum was more precious than gold.
I'm not a chemist, but I rather feel that you'd only be able to combine the Al and the Si. But on a little research, indeed a few of the silicides exist, including a Mg variant, which when mixed with HCl, produces a gas Silane, SiH4, the Si analog of Methane. But more reactive. Given that He is a noble gas, it may not combine.
