lead has an atomic number of 82;iron has an atomic number of 26; and copper has an atomic number of 29.how do the charges of the nuclei of these 3 elements compare?
The charges of the nuclei of these three elements can be determined by looking at their atomic numbers. The atomic number of an element represents the number of protons in the nucleus.
1. Lead (atomic number 82): The charge of the lead nucleus is +82.
2. Iron (atomic number 26): The charge of the iron nucleus is +26.
3. Copper (atomic number 29): The charge of the copper nucleus is +29.
Therefore, the charges of the nuclei of lead, iron, and copper are +82, +26, and +29, respectively.
The charges of the nuclei of different elements can be determined by the number of protons in their atomic nuclei, which corresponds to their atomic number.
Lead (atomic number 82) has 82 protons in its nucleus. Since protons have a positive charge of +1, the charge of the lead nucleus is +82e (where "e" represents elementary charge).
Iron (atomic number 26) has 26 protons in its nucleus. Hence, the charge of the iron nucleus is +26e.
Copper (atomic number 29) contains 29 protons in its nucleus. Therefore, the charge of the copper nucleus is +29e.
To summarize, the charges of the nuclei of lead, iron, and copper are +82e, +26e, and +29e, respectively.
