3 = 1 + 2 and 8 = 2+2+2 so 3 X 8 = (1+2)(2+2+2)= (1)(2 + 2+ 2) + (2)(2 + 2 + 2)=
1 X 2 + 1 X 2 + 1 X 2 + 2 X 2 + 2 X 2 + 2 X 2 , so you know the
multiplication facts 1 X 2 = 2 and 2 X 2 = 4 and know to add, you can work the problem.
3 X 8 = 2 + 2 + 2 + 4 + 4 + 4 .
(1 x 3 ) x ( 2 X 4) = 24
3x8 with1s and 2s fact looks like this: =(2x8)+(1x8) =16+8 =24
6
2s + 16 = 4s - 6 Subtract 2s from both sides: 16 = 2s - 6 Add 6 to both sides: 22 = 2s divide both sides by 2: s = 11
100 2s for the hundreds digit of 200-30010 2s for the tens digit of 220-23010 2s for the ones digit of 200-300________________________________120 '2s'
(1 x 3 ) x ( 2 X 4) = 24
3 times 8 it's only 24 always
3x8 with1s and 2s fact looks like this: =(2x8)+(1x8) =16+8 =24
To find 3 x 8 using a 2s fact and a 1s fact, you can break down 8 into manageable parts. For instance, you know that 3 x 2 = 6 (a 2s fact) and 3 x 1 = 3 (a 1s fact). Then, you can combine these to find 3 x 8 by calculating 3 x (2 + 2 + 2) = 3 x 2 + 3 x 2 + 3 x 2, which equals 6 + 6 + 6 = 24. Alternatively, you can also use 3 x 4 (2s fact) and double it to get 24.
3 * 8 = (2 + 1)*8 = (2 * 8) + (1 * 8)
1s + 1s + 1 = 2s + 1
I think 7x3 is = to 21
In lithium, the orbital of highest relative energy is the 2s orbital. This is due to the fact that, in the electron configuration of lithium (1s^2 2s^1), the 2s orbital is farther from the nucleus compared to the 1s orbital, resulting in higher energy.
To find (3 \times 8) using 2s and 1s facts, you can break it down into simpler components. First, recognize that (8) can be expressed as (4 + 4), so (3 \times 8) can be rewritten as (3 \times (4 + 4)). This gives you (3 \times 4 + 3 \times 4). Since (3 \times 4 = 12), you can add (12 + 12) to get (24). Thus, (3 \times 8 = 24).
The 2s orbital is larger than the 1s orbital and is higher in energy.
the 1s orbital is closer to the nucleus and has a lower energy level compared to the 2s orbital. Additionally, the 2s orbital has a slightly higher energy, larger size, and can hold more electrons than the 1s orbital.
