Answer:
5. Selenium, because it does not have a stable, half-filled p subshell and adding an electron does not decrease its stability.
Explanation:
Electron affinity is the amount of energy released when an isolated gaseous atom accepts electron to form the corresponding anion.
Selenium:-
The electronic configuration of the element is:-
Arsenic:-
The electronic configuration of the element is:-
The 4p orbital in case of arsenic is half filled which makes the element having more stability as compared to selenium.
Thus, selenium has higher electron affinity because adding electron does not decrease the stability as in case of arsenic.
Explanation:
False, gray whales average 75 miles per day at a speed of 5 mph and is the longest annual migration of any mammal.
Answer : When the forces are acting in the same direction of movement of the object it can be said as sum of the two individual forces will be equal to the "NET FORCE" .
Example : If two forces (2 kids pushing in the same direction to move the object big box) act on an object(big box) in the same direction, then the net force is equal to the sum of the two forces.
<em>1 troy ounce is equal to 0.0685714 pound.</em>
<em>1 pound is equal to 14.5833 troy ounces.</em>
14.5833 x 1795 = 26177.0235
1 pound of gold is approximately $26177.03
