Answer:

The answer is B

Explanation:

Less air means less air pressure. At a certain point, there is very little air pressure to push against the outward pressure of the helium inside the balloon. It will then expand until the rubber breaks, and the balloon bursts

The following Lewis diagram represents the valence electron configuration of a main-group element. This element is in group 2A A

Paraphin [41]

Answer: The symbol of the ion formed is $Ca^{2+}$

Explanation:

An ion is formed when a neutral atom looses or gains electrons.

When an atom looses electrons, it results in the formation of positive ion known as cation.
When an atom gains electrons, it results in the formation of negative ion known as anion.

Electronic configuration is defined as the representation of electrons around the nucleus of an atom.

Number of electrons in an atom is determined by the atomic number of that atom.

The element present in Group 2-A and in period 4 is Calcium (Ca)

Electronic configuration of Ca atom: $1s^22s^22p^63s^23p^64s^2$

This atom will loose 2 electrons to attain stable electronic configuration similar to Argon element (noble gas)

The electronic configration of $Ca^{2+}\text{ ion}=1s^22s^22p^63s^23p^6$

Hence, the symbol of the ion formed is $Ca^{2+}$
