6+6=12, x2=24, x2=48, +2 is 50
you do 2 + 2
You can use three 2s to make 26 as follows (2x2)! + 2 = 26 So you can simply make 26 with five 2s as (2x2!) + 2 - 2 + 2 = 26
If 2s = 5 then s = 2.5. So by letting s equal 2.5 (two and one half) you will allow 2s to equal 5.
2s 3d = two shillings and threepence (often 'thruppence'). Alternatively, 'two and three'. (Postscript. The UK adopted the present decimal currency on 15 February 1971).
The electron configuration of nitrogen is 1s^2 2s^2 2p^3. Nitrogen has a total of seven electrons, with two in the 1s orbital, two in the 2s orbital, and three in the 2p orbital.
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
two
2s + 3o2 --> 2so3
36
4194304 = 222
2s-4 equals 2(s-2). You can find the answer by factoring two out of both numbers.
22+22
