FOCUS QUESTION Why do elements in the same group have similar properties?

Chemistry
2 answers:
SIZIF [17.4K]3 years ago
7 0

Answer:

  1. Elements of the  the same group have similar number of valence electrons.
  2. They have identical number of electrons in their outermost shell. For example ;  All the alkali metals in Group 1 have 1 valence electron.

And so many more.

Due to all these similarities ,they have similar  properties and they tend to react similarly with other substances.

Answer:

The number of valence electrons.

Explanation:

Electrons mainly have to do with the reactions and how bonds are formed between elements. Elements are placed in groups based on the number of valence electrons. The number of valence electrons determine the element's properties such as its reactivity with other elements. Therefore, the reason why elements in the same group have similar properties is because each group has the same amount of valence electrons (number of electrons in outermost shell) which affects its properties.

At what temperature will a solid melt?
jolli1 [7]

<u>Answer</u>:

A solid will melt at the temperature at which the kinetic energy breaks the inter-molecular attractions.

<u>Explanation</u>:

The melting point is the state at which "a substance changes its temperature from a solid to  liquid". At the melting point temperature, there is an equilibrium between the both the solid and the liquid phase. When the solid particle is heated by increasing the temperature the particle in the solid vibrate quickly and it absorbs kinetic energy.

It leads to the breaking of the organisation of particle in between the solid and that leads to the melting of solid. Thus, at the melting point, the kinetic energy breaks the inter-molecular attractions.
