3 times 8 it's only 24 always
I think 7x3 is = to 21
To get the 2s complement, find the 1s complement (by inverting the bits) and add 1. Assuming that number is [4-bit] binary it would be 1000. If it is preceded by 0s, as in, for example, 0000 1000, then it would be 1111 1000.
2s-4 equals 2(s-2). You can find the answer by factoring two out of both numbers.
One way is using the Twos (2s) complement; that is you find the binary representation of the positive number of -19, flip all the bits (0s to 1s and 1s to 0s), and finally add 1 to it.The positive bit of -19 is simply 19. It has a binary code of 0001 0011 (8 bits are required for this particular method). Flipping the bits, we get 1110 1100. Adding 1 (or 0000 0001) to our last answer, we get 1110 1101 which would be the binary representation of -19.
3x8 with1s and 2s fact looks like this: =(2x8)+(1x8) =16+8 =24
3 times 8 it's only 24 always
3 * 8 = (2 + 1)*8 = (2 * 8) + (1 * 8)
I think 7x3 is = to 21
(1 x 3 ) x ( 2 X 4) = 24
1s + 1s + 1 = 2s + 1
The 2s orbital is larger than the 1s orbital and is higher in energy.
For a 2s subshell to be present, the 1s subshell must first be full, which means no more electrons can be moved into the 1s subshell.
Na(1s^2 2s^2 2p66 3s^1) + F(1s^2 2s^2 2s^5) ----> NA+(1s^2 2s^2 2p^6) + F-(1s^2 2s^2 2p^6) Don't you love E20-20?
The Electronic Configuration for Neon is as follows: 1s^2, 2s^2, 2p^6
1s, 2s, and 2p
lithium atom is just a ball it has 1s and 2s orbitals both of which are spheres the 1s is occupied by two electrons and the 2s one electron
