As a whole number answer NO!!!! As a decimal yes!!! 8/18 = 4/9 = 0.4444..... ( recurring to infinity.
No. A number cannot be a multiple of a number greater than it. 18 is greater than 8 so 8 cannot be a multiple of 18. Nor is 8 a factor of 18. The factors of a number are those numbers which divide into it without remainder.
18/8 = 22/8 which simplifies to 21/4
5 8/18 Work out how many 18s go into the top number, until there is a remainder, in this case 5 18s go into 98 and leaves us with 8 spare.
The number that is 10 greater than 8 is 18. This can be calculated by adding 10 to 8, which equals 18. In mathematical terms, this can be represented as 8 + 10 = 18.
The number 8 is the factor of 18. But 8 is not a multiple of 6.
The atomic number of oxygen is 8. So it has 8 protons. And O-18 isotope has 10 neutrons.
An oxide ion (O2-) formed from an oxygen-18 atom contains 8 protons, 10 neutrons, and 10 electrons. The number of protons is the same as the atomic number (8) of oxygen, while neutrons are added to the mass number (18-8=10). The ion gains 2 electrons to achieve a -2 charge.
The number of electrons in the electron shells are 2, 8, 18, 18, 8.
Two.
The atomic number of an isotope is the number of protons it contains, whereas the mass number is the total mass of the nucleus, which is the combined number of protons and neutrons in the nucleus. To find the number of neutrons, you must therefore subtract the atomic number of the isotope from the mass number of the isotope.In the above example, the atomic number is 8 and the mass number is 18. This isotope is known as O18. The number of neutrons in the isotope is: Mass number - Atomic number = Number of neutrons18 - 8 = 10
To find out how many times 8 goes into 145, we need to divide 145 by 8. The quotient is the whole number answer to the division problem. When we divide 145 by 8, we get 18 with a remainder of 1. So, 8 goes into 145 18 times with a remainder of 1.
