Explanation needed please!
VashaNatasha [74]

Answer:

Below

Explanation:

2) there are 28 protons in this isotope

     The number that is on the bottom of the "stacked pair" tells you how many protons are in this isotope. It is often represented by the variable Z.

3) there are 35 neutrons in this isotope

     Subtract the number of protons (28) from the top number

4) there are 28 electrons in the neutral element of Nickel

     If you were to look at the period table and find Ni, you would see that its atomic number is 28. This number tells us the amount of protons and electrons there are in that element.

5) 62.9296694 atomic mass units

     Just search it up (unless your teacher wants you to calculate it)

6) there are 92 protons in this isotope

     Again just look at the Z value to find the proton count

7) there are 146 neutrons in this isotope

     Subtract 238 - 92 = 146

8) there are 92 electrons in the neutral element of uranium

     Again just look at the periodic table and find U

9) 238.0507882 atomic mass units

10) 12C or carbon 12 is more likely to bond with oxygen that 14c carbon 14

     This is because 12C is more abundant at 98.93% than 14C

Hope this helps! Best of luck <3

If an element has 4 naturally occuring isotopes, how many peaks will show up in the mass spectra?
BartSMP [9]

Base peak: The most intense (tallest) peak in a mass spectrum, due to the ion with the greatest relative abundance (relative intensity; height of peak along the spectrum's y-axis). Not to be confused with molecular ion: base peaks are not always molecular ions, and molecular ions are not always base peaks.
