Titanium has an atomic number of 22. How many protons, neutrons, and electrons are in an isotope of titanium with mass number of 48?
p = 22 n = 26 e = 22
p = 11 n = 26 e = 11
p = 11 n = 11 , e = 70
p = 11 n = 22 e = 48
p = 22 n = 22 e = 48
The Correct Answer and Explanation is :
The correct answer is:
p = 22, n = 26, e = 22
Explanation:
- Understanding Atomic Number (Z):
The atomic number of an element represents the number of protons in its nucleus. For titanium (Ti), the atomic number is 22, meaning every titanium atom has 22 protons. - Mass Number (A) and Neutrons (N):
The mass number of an isotope is the sum of its protons and neutrons. Given that the isotope has a mass number of 48, we can determine the number of neutrons using the formula: [
\text{Neutrons} = \text{Mass Number} – \text{Protons}
] [
N = 48 – 22 = 26
] So, this isotope of titanium has 26 neutrons. - Electrons in a Neutral Atom:
In a neutral atom, the number of electrons equals the number of protons because the positive and negative charges balance out. Since titanium has 22 protons, a neutral titanium atom also has 22 electrons. - Checking Answer Choices:
- p = 22, n = 26, e = 22 ✅ (Correct)
- p = 11, n = 26, e = 11 ❌ (Wrong proton count)
- p = 11, n = 11, e = 70 ❌ (Wrong proton count, incorrect neutron-electron balance)
- p = 11, n = 22, e = 48 ❌ (Incorrect)
- p = 22, n = 22, e = 48 ❌ (Wrong neutron and electron count)
Since titanium-48 is a naturally occurring isotope, understanding its structure helps in material science, particularly in aerospace and biomedical applications.
Now, I’ll generate an image to visually represent the atomic structure of titanium-48.
Here is the atomic model of titanium-48, showing the correct number of protons, neutrons, and electrons. Let me know if you need any modifications or further explanations!
