How many elements occur in each of the first three periods or the periodic table?
There are 2 elements in the first period, 8, 8 elements in 2nd and 3rd periods respectively,
What to all of the elements in period three have in common?
All the elements in third row have 3 shells. The electron enters in the third shell for all the groups.
How does fluorines electronegativity compared to the electronegativity of oxygen and chlorine?
:0 OMG dont tell me u dont know?! hahahaha...losser!
How does fluorine's electronegativity compare to the electronegativity of oxygen and chlorine?
Fluorine is more electronegative than oxygen and chlorine. There are many scales used to measure electronegativity. Each is different. Oxygen and chlorine usually have an electronegativity value between 3.2 and 3.5 depending on the scale. Fluorine has an electronegativity of 4, the highest number on the scale. This means that the difference in electronegativity of fluorine and oxygen or chlorine is between 0.5 and 0.8 depending on the scale. This is the amount necessary to form a polar covalent bond.
What are three elements in the same period?
H and He are in the first period. Li Be, B, C, N, O, F, Ne are in the second and so on. A period is one row across on the periodic table
How does fluorine's electronegativity compare to the electronegativigty of oxygen and chlorine?
Fluorine has the highest electronegativity among the three elements. Oxygen is the second most electronegative, while chlorine has a slightly lower electronegativity compared to both fluorine and oxygen.
