Click ‘Get Form’ to open the protons, neutrons, and electrons practice worksheet in the editor.
Begin by locating the section for the element you wish to analyze. Each row contains fields for the name of the element, its symbol, mass number, atomic number, and counts for protons, neutrons, and electrons.
Use the periodic table to find the atomic number of your chosen element. Enter this value in the 'Atomic Number' field; this will also represent the number of protons.
Next, calculate the number of neutrons by subtracting the atomic number from the mass number. Fill in this value in the 'Neutrons' field.
Since electrons equal protons in a neutral atom, simply copy the value from 'Protons' into 'Electrons'.
Repeat these steps for each element listed on your worksheet until all fields are completed.

What is the number of protons neutrons and electrons in 80 by 35 Br?

- The mass number of bromine is 80. - Number of protons in bromine are 35. - Therefore the number of neutrons = 80 - 35 = 45. - So, the number of protons, electrons and neutrons present in bromide anion is 35, 36 and 45 respectively.

What is the number of neutrons protons and electrons atomic number 92 and mass number 238?

The atomic number of uranium is 92, and the mass number of the isotope is given as 238. Therefore, it has 92 protons, 92 electrons, and 146 neutrons (238 - 92 = 146).

How to calculate the number of protons, neutrons, and electrons?

in an atom, use its atomic number and mass number: number of protons = atomic number. number of electrons = atomic number. number of neutrons = mass number - atomic number.
