Answer:
The atomic number is 79 and the atomic mass is 197.
Explanation:
The atomic number (symbol Z) of a chemical element is the number of protons within its nucleus.
Gold (chemical symbol Au) is a chemical element with 79 protons in its nucleus, therefore with atomic number 79.
The atomic mass is the average mass of the atoms of an element (in atomic mass unit). The atomic mass is the weighted average of all the isotopes of a a particular element. For each isotope the atomic mass is approximately the mass of both protons and neutrons since electrons make minor contributions.
The atomic mass of Gold (Au) is 196.9665 but, it can be rounded to 197.

Answer:
Oxygen
Explanation:

Cells exposed to environmental factors known to cause mutations in genetic material will <u>become cancer cells</u>
<u>Explanation:</u>
Environmental factors like radiation and high concentration of chemicals are among the factors that cause mutation in the genetic material. Internal genetic changes causes mutation in the genetic material, the DNA there are many chances of the mutated gene to convert into an Oncogene.
An Oncogene is a genetically mutated gene which causes tumor. The mutated gene causes proliferation of cells. More than 90% of the cancer is caused by the carcinogenic substances present in the environment.
