The element iodine (I) is important for the fast and hastened metamorphosis of frog-tadpoles. As amphibians, the tadpoles can live in water and land but when they are born they are iodine-deficient. Tadpoles that do not receive ample amount of iodine become tadpoles until the end of their days.

When two fluorine atoms bond together in F2, what type of covalent bond do they form?
makvit [3.9K]

When two  fluorine  atoms  bond  together  in f2  the  type of covalent  bond   do they  form is non-polar covalent   bond.


  Explanation

They are  two type of covalent bond.  that is non polar covalent bond and  polar covalent  bond.


Non polar  covalent  bond  is formed  when atoms share  a pair  of electrons  with each other  equally.

polar covalent  bond is bond formed when  atoms share  a pair   electrons unequally.


 F2  is a non polar  since  it is made  up of two  same atoms   which  has  the  same electronegativity, therefore equal number of electrons exist  in the  orbital overlap.
