Answer:Strontium (Sr) and Gallium (Ga)
Explanation:
Strontium (Sr) and Gallium (Ga) are the elements which have fewer than four dots in the electron dot diagrams. Explanation: Electron dot diagrams are the diagrams which represent the valence electrons in an element. The electrons are represented by the dots in these diagrams.
Answer:
OF6
Explanation:
Oxygen and fluorine have almost the same electronegativity, so oxygen isn't able to donate enough electron density to fluorine to form OF6. Atomic size. There isn't enough room around an oxygen atom for six fluorine atoms.

Answer:
Number 1 is A (I'm not sure but i think it is) and Number 2 is correct (I think)
Explanation:
solution:
The general form of the equation would be A = P x (1/2) ^ (t/h) where A = final amount, P = start amount, t = time (here in days) and h = half-life (has to be same units as t)
a) A = 192 x (1/2) ^ (15/5) = 192 x (1/2) ^3 = 192 x 1/8 = 24 mg
Because if you have a liquid then you need a glass to keep it together and when it is a solid it is already together so you don't need to do anything
