Answer:
Cu
Explanation:
Groups 3 - 12 (or groups IIA - IIB) of the periodic table contain transition elements. Transaction elements start from period four (4) of the periodic table. The phrase alludes to the fact that the d sublevel is filling at a lower main energy level than the s sublevel that came before it.
The transition elements' arrangement is inverted from the fill order, with the 4 s filled prior to the actual 3 d begins. The transition elements are commonly referred to as transition metals since they are all metals. They are less reactive than the metals in Groups 1 and 2 and have normal metallic characteristics.
From the options given Cu is the only transition metal in the fourth period on the periodic table.
Kinetic energy is from speed, motion, and mass while potential energy is stored energy
No because they have the same number of protons not neutrons. fine, their mass nos are equal but isotopy is due to different number of neutrons.
When the football is on its way up, Kinetic energy is being transformed into Gravitational Potential energy.
