the mass number of a chromium Atom is 52 and it has 24 protons. How many neutrons does this atom have?
2 answers:
Answer:
It has 28 neutrons
Explanation:
Hi, by definition the mass number of an element if given by:
Knowing the mass number of chromiun and the amount of protons it has:
It has 28 neutrons
Chromium has a total of 28 neutrons . This is found because we subtract the number of protons (the atomic number) from the mass number. 52 minus 24 gives us 28. It also has 24 electrons.

Down a period, atomic radii decrease from left to right due to the increase in the number of protons and electrons across a period.
Iodine is going to form anions capturing electrons from some other element more electropositive
Chunky peanut butter is a mixture which is NOT uniform throughout, so it is heterogeneous mixture .
by definition
.. % yield = (actual yield / theoretical yield) * 100%
so
.. % yield = ((⅓ theoretical yield) / (theoretical yield)) * 100%
.. % yield = (⅓) * 100% = 33%
