an atom of tungsten (w) has 74 protons. the atomic mass of tungsten is 183.84. how many neutrons does an atom of tungsten have? round your answer to the nearest whole number.

Answer

Explanation:

Step1: Recall atomic - mass formula

Atomic mass ≈ number of protons + number of neutrons.

Step2: Rearrange the formula to find neutrons

Number of neutrons = Atomic mass - number of protons.

Step3: Substitute the given values

Given number of protons = 74 and atomic mass = 183.84. So, number of neutrons = 183.84 - 74.

Step4: Calculate and round

183.84 - 74 = 109.84. Rounding 109.84 to the nearest whole number gives 110.

Answer:

110
