Detailed explanation-1: -16) Carbon(2.55) has higher electronegativity than As(2.18). Hence, carbon has greater tendency to attract a shared pair of electrons towards itself as compared to As. 17) Calcium has lower ionisation energy than Scandium . This is due to having less …
Detailed explanation-2: -Since bromine is to the right of arsenic, bromine has a greater electronegativity than arsenic.
Detailed explanation-3: -Electronegativity is the tendency of an atom to attract electrons. In general, electronegativity increases on passing from left to right along a period and decreases on descending a group. So, O has the highest electronegativity as compared to other elements.
Detailed explanation-4: -Fluorine has an electronegativity value of 4.0 and Carbon has an electronegativity value of 2.5. This is telling us that Fluorine is much more electronegative than Carbon.
Detailed explanation-5: -Calcium is near the left side in main group 2A (group 2), while arsenic is near the right side in main group 5A (group 15). In general, the electronegativity increases when going to the right across a row. Therefore, we predict that arsenic will have a higher electronegativity.
