What are the number of protons, neutrons, and electrons in the following isotopes ?
14 ^ 28 Si
The number of protons is determined by the atomic number, which is 14 in this case as indicated by the superscript. Therefore, there are 14 protons in this isotope.
The number of neutrons is determined by subtracting the atomic number from the mass number. The mass number is indicated by the superscript and is equal to the total number of protons and neutrons. In this case, the mass number is 28, and the atomic number is 14. Thus, there are (28 - 14) = 14 neutrons in this isotope.
The number of electrons is typically equal to the number of protons in a neutral atom; therefore, in this case, there are also 14 electrons.
To determine the number of protons, neutrons, and electrons in an isotope, you need to understand its atomic structure.
The atomic number of an element tells us the number of protons in its nucleus. For the isotope 14^28Si, the atomic number is 14. Therefore, the number of protons is 14.
The mass number of an isotope is the total number of protons and neutrons in its nucleus. For 14^28Si, the mass number is 28. Given that the number of protons is 14, we can calculate the number of neutrons by subtracting the atomic number (protons) from the mass number:
Number of neutrons = Mass number - Atomic number
Number of neutrons = 28 - 14
Number of neutrons = 14
Therefore, the number of neutrons in 14^28Si is 14.
The number of electrons in a neutral atom is equal to the number of protons. Since the atomic number of silicon is 14 and the isotope 14^28Si also has 14 protons, the number of electrons is also 14.
In summary:
- Number of protons: 14
- Number of neutrons: 14
- Number of electrons: 14
To determine the number of protons, neutrons, and electrons in an isotope, we need to understand what each of these particles represents in an atom.
1. Protons:
Protons are positively charged particles found in the nucleus of an atom. The number of protons defines the atomic number (Z) of the element, which is unique to each element.
To find the number of protons in the isotope 14^28Si, we look at the superscript number, "28." This number represents the total number of nucleons (protons + neutrons) in the isotope. Since protons define the atomic number, the number of protons in the isotope is 14.
2. Neutrons:
Neutrons are neutral particles found in the nucleus of an atom. The difference between the atomic mass number (A) and the atomic number (Z) gives us the number of neutrons in an isotope.
In the isotope 14^28Si, the superscript number "28" represents the total number of nucleons. Since the atomic number (Z) is 14, the number of neutrons can be calculated as A - Z = 28 - 14 = 14 neutrons.
3. Electrons:
Electrons are negatively charged particles that orbit the nucleus of an atom. In a neutral atom, the number of electrons is equal to the number of protons.
Since the number of protons in the isotope 14^28Si is 14, the number of electrons will also be 14.
Therefore, in the isotope 14^28Si:
- Number of protons (Z) = 14
- Number of neutrons (A - Z) = 14
- Number of electrons = 14
