18 is 40% of 45.
To find 18 percent of a number, multiply the number by 0.18. In this instance, 0.18 x 40 = 7.2. Therefore, 18 percent of 40 is equal to 7.2.
60% of 12 = 7.27.2 is 40% of 18
The number 68.
18 is what percent of 40= 18 / 40= 0.45Converting decimal to a percentage:0.45 * 100 = 45%
18 is 40% of 45.
The atomic number of argon (Z) is 18, which means it has 18 protons. The mass number (A) is 40, so subtracting the atomic number from the mass number gives you the number of neutrons. In this case, 40 - 18 = 22 neutrons.

Argon-40 has 18 electrons. This is because argon has an atomic number of 18, which indicates the number of protons (and electrons) in a neutral atom of argon.
The number 40 in argon-40 represents the total number of protons and neutrons in the nucleus of an argon atom. It is the mass number of argon-40, which is the sum of the number of protons (18) and neutrons (22) in the nucleus.
ARGON has 18 electrons, with an atomic number of 18 and an Atomic Mass of 40. It has 22 neutrons, is considered a Nobel gas, in that it is inert under most conditions, and is colorless.
