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.
Oxygen-18 has 8 protons, which defines it as an oxygen atom. The number after the element name indicates the total number of protons and neutrons in the nucleus.
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 number of neutrons can be calculated by subtracting the atomic number from the atomic weight. In this case, for oxygen with an atomic number of 8 and an atomic weight of 18, it would have 10 neutrons (18 - 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.
