L = r x p = rmv = mr²ω
L = 0.25 x 0.75² x 12.5 = 1.758

Answer:
By holding another magnet close to it. If the object is attracted to the magnet, then it too is magnetic.
Answer:
Lithium has the lowest electronegativity.
Explanation:
Electronegativity measures the tendency of an atom to attract the bonding pair of electrons. As we move left to right in a period, the number of shell remains same but the number of electron increases(negative charge increases. Hence, electronegativity also increases.
As Lithium is the left most element in this period. It has the lowest electronegativity value which is equal to 0.98.
