I have 1-7 down, I need the rest though, but only help, no answers :)
Electronegativity is a measure of the tendency of an atom to attract a bonding pair of electrons. The Pauling scale is the most commonly used. Fluorine (the most electronegative element) is assigned a value of 4.0, and values range down to cesium and francium which are the least electronegative at 0.7.
hydrogen=smallest atomic weight
UUo has highest atomic weight (man made) hassium has highest atomic weight (Natural)
are you answering the first 7? cause I already have those down dude :D
What do you need?
Record information on the everyday application of each element in at least two different products. This one
@nono266 are you there?
fluoride, are used in toothpaste and in drinking water to prevent dental cavities. Hydrofluoric acid can dissolve glass and is used to etch the glass in light bulbs and in other products.
Chlorine also has a multitude of industrial uses. Including making bulk materials like bleached paper products, plastics such as PVC and the solvents tetrachloromethane, chloroform and dichloromethane. It is also used to make dyes, textiles, medicines, antiseptics, insecticides and paints.
One of the major uses of bromine is as a water purifier/disinfectant. Brominated compounds are used for water treatment in swimming pools and hot tubs. They are also used to control algae and bacterial growth in industrial processes.
Iodine reduces thyroid hormone and can kill fungus, bacteria, and other microorganisms such as amoebas. A specific kind of iodine called potassium iodide is also used to treat (but not prevent) the effects of a radioactive accident.
Astatine=> Radioactive treatment and cancer treatment
@nono266 do I have to do more?
if you feel like it man
okay... till now was the answers useful?
Hydrogen as water (H2O) is absolutely essential to life and it is present in all organic compounds.
Mercury has no biological role but is widespread in the biosphere and in food chains, including ours.
Oxygen atoms are present in water (H2O) and water is essential to all life. Oxygen and is present in many organic compounds. Most organisms use oxygen for respiration. While oxygen (O2) is necessary for life, oxygen as ozone (O3) is highly toxic. On the other hand, ozone is an important component of the atmosphere (the ozone layer) and helps to shield us from harmful ultraviolet rays from the sun.
Liquid neon has over 40 times more refrigerating capacity than liquid helium, and more than 3 times that of liquid hydrogen.
Neon has no biological role.
I guess I am done.... If you like it, don't forget to medal
