Which element has one 2s electron?
Lithium
What is the highest occupied energy level in the element Beryllium?
2s
What element has two 2s electrons?
Actually the atomic number tells you how many protons there are. And there are 6 elements with 2 electrons. You can find out that out by looking at a periodic table and looking at family 2. Im guessing you won't be able to find the element your looking for unless you know the number of nuetrons or even better the number of protons.
Which element has 1s 2 2s 2 2p 6 3s 1 as its electron configuration?
Sodium.
Which element is predicted to have the ground-state electron configuration He 2s 2 2p 2?
The configuration [He] 2s2 2p2 describes the element in the 2nd row (since He finishes the first row) in the second of the 'p' columns, #14. This corresponds to the element carbon.
What element has 2 electrons in the 1s sub-level 2 electrons in the 2s sub-level and 2 electrons in the 2p sub-level?
Carbon
How do you factor 4s2-9?
4s2 - 9 can be expressed by using the identity: a2 - b2 = (a-b)(a+b) Therefore, 4s2 - 9 = (2s)2 - 32 = (2s-3)(2s+3)
What is equevitent to 7s plus 2s?
The equivalent of 7s plus 2s is 9s.
What is the answer to 2s-12 plus 2s equals 4s-12?
2s - 12 + 2s = 4s - 124s - 12 = 4s - 124s = 4ss = s==========this is an identity and any number can be s
What is the answer to 2s plus 16 equals 4s - 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
1s 2 2s 2 2p 6 3s 2 2p 6 3d 3 4s 2 equals?
This is the arrangement of electrons in the element Calcium.
Why 2's complement binary subtraction is preffered over 1's complement binary subtraction?
