Answer:
42
Explanation:
Atoms have a neutral charge overall, which means they have an equal numbers of positively-charged protons and negatively-charged electrons. Here, an atom of arsenic with 33 electrons must also have 33 protons.
The mass of any atom is contained in its <em>nucleus</em>, a part made up of protons and neutrons - particles with no charge. Both protons and neutrons are exactly 1 atomic mass unit each, so to find the atomic mass of an atom, we can use the formula
(# of protons) + (# of neutrons) = atomic mass
or equivalently:
atomic mass - (# of protons) = (# of neutrons).
For arsenic, we have an atomic mass of 75 amu and 33 protons, so using our formula:
# of neutron = 75 - 33 = 42 neutrons
Inferences are related to observations because inferences are an explanation for an observation you have made.
The answer is : C. Gravity
The Gravitional forces that the stars and planet have are different from one another. The difference in gravities All the stars and planets in our solar system create an effect in which the stars and planets are pulling each other according the force of their gravity, which create our current orbits in the syste
Answer: There are 365 days in a year. The number of days in a year varied between the planets and the number of days in a year is depending on the number of times the planet orbits around the sun.
Explanation: I think this is the answer I’m not too sure though !
