How many neutrons does element's x have if it's atomic number is 52 and it's mass number is 153?
Over [174]
Answer: 101 neutrons

An element's atomic number is the number of protons in its nucleus. X has 52 protons. The mass number is simply the number of protons AND neutrons in the nucleus. Since 52 is given, it's correct to assume that the remainder consists of neutrons. 153-52 will give you the number of neutrons.

Hope this helps! :)

Gnesinka [82]
I would say the correct answer is B: <span>People tend to overuse or degrade shared resources. It is often not clear how much exploitative pressure a natural resource can sustain before the exploitation becomes unsustainable. So for example, various industries may dispose of waste into a river. The river has a capacity to absorb and clean a certain amount of effluent by natural degradation systems. However, at some critical mass of pollutants, these natural processes are no longer able to function properly, and the river becomes very polluted to a point were the resource cannot be utilised. Monitoring can help to gauge at which point a common resources is becoming unacceptably degraded, and this can guide policy.</span>
