Explanation : When Tito lifts the heaviest object, he is testing his strength.
We know, strength is the quality of the physical energy and potential of the person. The strength of the person is power and his capacity.

Answer:
This new element belongs to the group 2.
Explanation:
In the periodic table, the vertical columns are called groups (or families). The elements in the same group share similar chemical and physical properties.
One of these properties is the same amount of outer valence electrons.
For example, in the group 1 the elements have 1 outer valence electron (If we assume that the element is in a neutral state which is without electrical charges).
If this new element has 2 electrons in its outer level it will belong to the group 2. The group 2 is well-known as alkaline earth metals.
For example, the magnesium (Mg) and the calcium (Ca) belong to the group 2.
