P1/T1=P2/T2
3/(273+30)=P2/(273-5)
(3/303)(268)=P2
=2.65346 atm

How do molecules in a solid differ from those in a liquid or gas
artcher [175]
Molecules in solids are packed a lot closer together than molecules in liquids and gases, so there is far less space between solid particles. Because of this, solid particles cannot move around quickly and freely like liquids and gases, instead they only vibrate so are fairly 'locked' into the same place, so solids have fixed volume and space.

The following Lewis diagram represents the valence electron configuration of a main-group element. This element is in group 2A A
Paraphin [41]

<u>Answer:</u> The symbol of the ion formed is Ca^{2+}

<u>Explanation:</u>

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+}
