Answer:
An atom has a nucleus, made up protons and neutrons, which is surrounded by a cloud of electrons.
Explanation:
An atom is the smallest indivisible part of any element that takes place in a chemical reactions.
These are the fundamental building blocks of every element and even compounds.
- There are three known subatomic particles found within an atom.
- Electrons are the negatively charged particles in an atom
- Protons are the positively charged particles of an atom
- Neutrons do not carry any charges.
Both protons and neutrons are located within the tiny space called nucleus at the center of an atom.
Electrons moves round in orbitals at the spaces outside of the nucleus.
Answer:
1) increase
2) increase
Explanation:
Entropy is the degree of disorderliness or randomness of a system. It is the measure of the unavailable energy in a system.
Entropy increases with increase in the number of particles. If the number of particles in a system increases from left to right, the entropy of the system increases accordingly.
In reaction 1, the number of particles from left to right increased from two to three hence the entropy was increased.
In reaction 2, the number of particles from left to right increased from three to five hence the entropy was increased.
The collision of two plates causes the formation of fold mountains.
