Answer:
The term Big Bang defines that the Universe has expanded from the ancient hot and thick primary situation at some fixed time in the past.
Big Bang theory refers to the origin of the Universe. In the beginning, universe is very heavy and small hot ball of matter. It was a point no bigger than the head of a pin when all the things squished with each other and universe is expanded with huge explosion of energy. Due to expansion, it is cooled and results in the formation of Stars and galaxies. After sometime, atoms formed like helium and hydrogen.
Thus, statement (1), (3) and (4) is correct whereas statement (2) and (5) is incorrect. the right answer is - (It expanded slowly), (Stars and galaxies formed,) (Atoms such as hydrogen and helium formed.)
Explanation:
3. The answer is B. 11. This is because there are the same amount of electrons and protons in an atom, and since there are 11 protons, there are 11 electrons.
5. The formula H2O means that there are 2 hydrogen atoms (because the 2 is after the H), and 1 oxygen atom, so the answer is C.
Hope this helps!
