Answer:

The given statement is True.

Coral bleaching is a stressed condition in which is caused by the warmer temperatures.

The number of protons determines the _____. atomic number atomic mass atomic structure atomic charge

Answers

Answer:

atomic number

Explanation:

Final answer:

The number of protons in an atom determines its atomic number, which is a defining trait of an element. In a neutral atom, the same number of protons also equals the number of electrons. However, the mass number or atomic mass is the total number of protons and neutrons.

Explanation:

The number of protons in the nucleus of an atom determines its atomic number. This is a defining trait of an element and determines its identity. For instance, any atom with six protons is the element carbon, which has an atomic number of 6 - this applies irrespective of the number of neutrons or electrons present.

Moreover, in a neutral atom, there must be an equal number of positive and negative charges implying that the number of protons is equal to the number of electrons. Thus, the atomic number indicates not only the number of protons but also the number of electrons in an atom.

The atomic mass or mass number of an atom, on the other hand, is the total number of protons and neutrons in an atom. Therefore, you can derive the number of neutrons by finding the difference between the mass number and the atomic number: (A - Z = number of neutrons).
