Question

e. circle the number in this entry from the periodic table that gives the number of protons.
6
c
12.01
f. the mass of a proton is ____________.
g. protons are one of the ( heavier / lighter ) parts of the atom.
h. all protons have a ________ charge.

Explanation:

Part e

Step1: Recall periodic table info

In a periodic table entry, the atomic number (the number at the top left) equals the number of protons. For carbon (C), the top - left number is 6. So we circle 6.

The mass of a proton is approximately \(1.67\times 10^{-27}\) kilograms or 1 atomic mass unit (amu), where 1 amu is approximately equal to \(1.67\times 10^{-27}\) kg.

Protons are located in the nucleus of an atom. Compared to electrons (which have a much smaller mass), protons are one of the heavier parts of the atom. Electrons have a mass of approximately \(9.11\times 10^{-31}\) kg, while protons have a mass of approximately \(1.67\times 10^{-27}\) kg. So protons are heavier.

Answer:

Circle the number 6.
