How many neutrons and protons are there in each of the following nuclides:(a) 10B. (b) 24Na, (c) 59Co, (d) 208Pb. and (e) 235U?

a. 5 protons and 5 neutrons

b. 11 protons and 13 neutrons

c. 27 protons and 32 neutrons

d. 82 protons and 126 neutrons

e. 92 protons and 143 neutrons

Explanation:

Using isotope notation:

ˣN

X = Amount of neutrons and protons

N is the atom. If N is nitrogen, the atomic number is 7, that means there are 7 protons.

X - Amount of protons = Neutrons

a. ¹⁰B. Atomic number = 5 = Number of protons

10 - 5 = 5 = Number of neutrons

5 protons and 5 neutrons

b. ²⁴N. Atomic number = 11 = Number of protons

24 - 11 = 13 = Number of neutrons

11 protons and 13 neutrons

c. ⁵⁹Co. Atomic number = 27 = Number of protons

59 - 27 = 32 = Number of neutrons

27 protons and 32 neutrons

d. ²⁰⁸Pb. Atomic number = 82 = Number of protons

208 - 82 = 126 = Number of neutrons

82 protons and 126 neutrons

e. ²³⁵U. Atomic number = 92 = Number of protons

235 - 92 = 143 = Number of neutrons

92 protons and 143 neutrons

c- cold periods in earth's history during which glaciers covered much of the surface.

explanation:

it forms an anion that has a larger radius. anions have a negative charge and are larger than the original atom.
