The one with the lower atomic/molecular mass
C. Beryllium. Which has 112 pm
Answer:
The oxygen atom has a slightly negative charge.
Explanation:
3.5 - 2.5 = 1
For ionic bond electronegativity should be more than 1.6.
So, O and C do not have whole charge. Electronegativity of O more than C, so electrons slightly moved to the oxygen side.
Explanation:
probably because, X rays are used to ionise the gas molecules, which is loss of electrons, these electrons are absorbed by oil drops
Salt water is considered a compound since water is H20 (conpound) and Salt with is NaCl.
