Zorluk: OrtaAtomic Structure and Periodic Table

During a mass spectrometry investigation, researchers identify an isotope of chromium with a mass number of 5252 and an atomic number of 2424. How many neutrons are contained in the nucleus of this chromium atom?

  1. A
    2424
  2. 2828Cevap
  3. C
    5252
  4. D

Cevap

2828 neutrons
The mass number (A=52A = 52) is the total number of protons and neutrons in the nucleus. The atomic number (Z=24Z = 24) indicates the number of protons. Subtracting the atomic number from the mass number (52−24=2852 - 24 = 28) gives the total number of neutrons.

Adım Adım Çözüm

1
Identify the given atomic parameters
Mass number (AA) = 5252; Atomic number (ZZ) = 2424
The mass number represents the sum of protons and neutrons, while the atomic number represents the number of protons.
2
Apply the neutron calculation formula: Neutrons=A−Z\text{Neutrons} = A - Z
Neutrons=52−24=28\text{Neutrons} = 52 - 24 = 28
Subtracting the number of protons from the total nucleon count isolates the number of neutrons.
