How many 4s are in 36
If you mean '' __ x 4 = 28'' then the answer is 7. In a simple multiplication problem like this, you can get the answer two ways. Count by 4s until you get to 28. The number of 4s it took is the missing variable. Divide 28 by 4. The answer is the missing variable.
There are no 4s in number 38.
The electron configuration 4s²3d⁸ corresponds to the element nickel (Ni), which has an atomic number of 28. This configuration indicates that nickel has a total of 28 electrons, with the outermost electrons in the 4s and 3d subshells.
How many 4s are in 36
A = s^2 28 = s^2 s = 28^(1/2) P = 4s = 4[28^(1/2)] = 21.166 units (final answer)
20 4s go into 80.
4.56
The answer is 10
4x7=28 2(4x7)=2x28=56
