An atom's atomic number tells us the amount of protons it has. If that atom is to remain neutral, it must also have the same number of electrons. Arsenic's atomic number is 33. Thus, it has 33 protons and 33 electrons.

What Element With 18 Neutrons And Mass Number Of 35 Is?

Atomic number = Number of protons = 35 - 18 = 17.So the element is chlorine.


What is the science element that has 18 neutrons?

Chlorine maybe? It has 17 protons and a mass of 35, so 35-17= 18 neutrons.


What are the protons and the neutrons for the element Br?

Bromine-79 has 44 neutrons and bromine-81 has 46 neutrons. All the isotopes of bromine has 35 protons.


What atom has 44 neutrons 35 protons and 35 electrons?

The isotope of bromine called 81-bromine. Since the element you are describing has 35 electrons, it must also have 35 protons. Therefore you end up with bromine which is the 35th element (since the amount of protons are equal to the elements number). Adding 46 to 35 gives you the weight of the specific bromine isotope, since the weight of the element is also the name of the isotope. It is also not radioactive.


Why do isotopes represent the same element?

Isotopes are atoms of the same element that have differing numbers of neutrons. An example would be Cl-35 and Cl-37. Cl-37 has a larger amount of neutrons than Cl-35 has.


Determine the numbers of electrons protons neutrons 80 35 Br?

The element with atomic number 35 is bromine (Br). It has 35 protons and since it is neutral, it also has 35 electrons. To find the number of neutrons, subtract the atomic number (35) from the atomic mass (80). So, bromine-80 has 45 neutrons.


What is the number of neutrons in an atom with atomic mass of 35?

cannot say without knowing the element, that is the number of protons.Sulfur-35, radioactive; 19 neutronsChlorine-35, stable; 18 neutronsArgon-35, radioactive; 17 neutrons


Which element has 19 protons 35 electrons 2 neutrons and 201 particles in the nucleus?

This element doesn't exist.


If Bromine has an atomic number of 35 and has 45 neutrons what is its mass number?

The mass number of an element is the sum of its protons and neutrons. Since Bromine has 35 protons (atomic number) and 45 neutrons, its mass number would be 35 + 45 = 80.


What is the mass number of cl35?

The mass number of the element chlorine is 35.5. The mass number (nucleon number) of an isotope of an element tells us the sum of the number of neutrons and protons. It is a decimal because mass numbers of elements are averages, based on the different isotopic forms of the element and their relative abundance.


What is the atomic number for an element with 37 neutrons and a mass number of 72?

The mass number is the amount of protons and neutrons in an element. The atomic number is equal to the amount of protons. Therefore to get the number of protons from the given information, you would subtract 37 from 72 which gives you 35 protons aka its atomic number!


How many neutrons are in an atom of sulfur with a mass number of 35?

Sulfur is a non metal element. Mass number of it is 32.
