Answer:
18 neutrons
Explanation:
- The atomic number of sulfur is 16.
- Atomic number indicates the number of protons in the nucleus of an atom.
- Neutrons are found in the nucleus of an atom together with the protons and account for the difference in the mass number among isotopes of an element.
- The sum of neutrons and protons gives the atomic mass number of an element.
- Therefore; given the mass number and the atomic number(number of protons) we can calculate the number of neutrons.
Number of protons = 16
Mass number = 34
Number of neutrons = mass of number - number of protons
= 34 - 16
= 18 neutrons
It should be D, cells are parts, tissue is part and organ is part of a system.
Density is the mass of a substance per unit volume. Volume is the amount of space an object occupies. Chemical properties- These are properties that can only be observed by changing the identity of the substance
