False.
It is expected to be 7.5, the mean of 7 and 10.
Increases
Stays the same
s-orbitals
d-orbitals
p-orbitals
Explanation:
The trend in the electronic configuration on the periodic table follows a definite pattern because the arrangement of elements on the table is based on the periodic law.
The periodic law states that "The properties of elements are a function of their atomic number".
- Elements in the same horizontal period have increasing number of valence electrons.
- The number of valence electrons stays the same down a group.
- Groups 1 and 2 are known as the s-block and electrons are added to the s-orbitals for them.
- Groups 3 to 12 is the transition block and electrons the valence d-orbital.
- Groups 3 through 18 is the p-block where the valence shell is the p-orbital.

- Reversible
- Irreversible
- Irreversible
- Irreversible
- Reversible
- Reversible
- Irreversible
- Irreversible
Explanation:
The concept applied here is the application of change of state as such ,
A reversible reaction is one that can go in both ways, that is the forward reaction can react to produce the product and the backward reaction can also react to give back the reactants. In a reversible reaction, no new substances are formed and the heat evolved is not much compared to Irreversible reaction.
An Irreversible reaction is one that can not go in both ways. i.e reactants can react to give products but products cant react to give back the reactants. In irreversible reaction, new substances are formed and a huge amount of heat is evolved.
There is reversibility between melting point and freezing point, the differences is if the solid is melting above its melting point, in such case, it is an irreversible reaction.
