The value of Z for an atom containing 29 protons, 29 electrons, and 34 neutrons is:
A. 58
B. 34
C. 29
D. 63
E. 5
Answer (2)
Z represents the atomic number.
The atomic number is the number of protons in an atom's nucleus.
The atom in question has 29 protons.
Therefore, the value of Z is 29 .
Explanation
Understanding the Problem We are given an atom with 29 protons, 29 electrons, and 34 neutrons. The question asks for the value of Z. We need to determine what Z represents and how it relates to the given information.
Identifying Z Z represents the atomic number of an element. The atomic number is defined as the number of protons in the nucleus of an atom.
Determining the Value of Z Since the atom has 29 protons, the atomic number Z is equal to 29. The number of electrons and neutrons are not relevant for determining the atomic number.
Final Answer Therefore, the value of Z for this atom is 29.
Examples
In chemistry, the atomic number (Z) is crucial for identifying elements and understanding their properties. For example, carbon has an atomic number of 6, meaning every carbon atom has 6 protons. Similarly, oxygen has an atomic number of 8, indicating 8 protons in each oxygen atom. Knowing the atomic number allows us to predict how an element will interact with others, forming the basis of chemical reactions and compound formation. This concept is fundamental in fields like material science, where selecting elements with specific atomic structures is essential for designing new materials with desired properties.
The value of Z for the atom is 29, as Z represents the atomic number, which is equal to the number of protons. Given that this atom has 29 protons, the answer is 29. The correct option is C.
