Question

an atom or ion has 41 neutrons, 36 protons, and 36 electrons. identify the element symbol, and determine the mass number and charge for this atom or ion. element symbol: mass number: charge:

Explanation:

Step1: Identify the element

The number of protons determines the atomic number of an element. Here, the number of protons is 36. Looking at the periodic table, the element with atomic number 36 is Krypton, symbolized as Kr.

Step2: Calculate the mass number

The mass number (A) is the sum of the number of protons (p) and neutrons (n). Given p = 36 and n = 41, we use the formula A=p + n. So, A=36 + 41=77.

Step3: Determine the charge

The charge of an atom or ion is given by the difference between the number of protons and electrons. Here, the number of protons is 36 and the number of electrons is 36. Charge=Number of protons - Number of electrons = 36 - 36=0.

Answer:

element symbol: Kr
mass number: 77
charge: 0
