Explanation:
The sum of total number of protons present in an element is known as atomic number of the element.
- As atomic number of Cs is 55.
And, it is known that for a neutral atom the number of protons equal to the number of electrons.
Since, no charge in present on given Cs atom it means that it is neutral in nature. Hence, number of protons and electrons present in Cs are 55.
- For Ba, it is also neutral in nature and atomic number of barium is 56. Hence, number of protons and electrons present in Ba are 56.
- For S, there is no charge on it so it is also neutral in nature. Atomic number of S is 16. Hence, number of protons and electrons present in S are 16.
Answer:According to the sliding filament theory, a muscle fiber contracts when myosin filaments pull actin filaments closer together and thus shorten sarcomeres within a fiber.
Explanation:
No need for an explanation if i just answered it
I would say answer choice A) positive after checking, hope this helps
Answer:
Nonmetals
Explanation:
Nonmetals typically lacks the metallic bonding which allows substances to exhibit metallic properties that confers special properties on them.
- Metals are malleable and ductile
- They are also able to conduct electricity due to the sea of electrons present within their structure.
- Metals can be made into wire and drawn into sheets.
Nonmetals lacks these properties but metalloids are able to show some of the properties under certain and special conditions.
