Be (beryllium) has four electrons total: the first orbital, the 1s orbital, has two, which leaves two electrons in the outer shell.
The atomic number of lithium (Li) is 3, and so it has 3 protons in the nucleus. The number of neutrons depends on which isotope of lithium you have. The most common isotope (92.5%) is 7Li with 4 neutrons.A neutral atom of lithium has three electrons in it. Lithium has two electron shells that have electrons in them. The 1s shell has a pair of electrons in it (the maximum), and the 2s shell has one electron in it. Note that this is a neutral atom of lithium, and lithium is reactive. It would like to loan that 2s electron out if it can. It will react with air, either with the oxygen in it or the moisture, if there is any.See the Related Questions below for more information about the particles in the nucleus.
Yes H has 1 e- in 1s shell but when H is treated with more electronegative atom then it loose it's e- n it's nucleus becomes naked due 2 which it becomes very reactive

how many number 1s did roxy music have
the beetles
The Beatles are the top group with 17 number 1s.
5 number 1s so far
It is most likely a glitch.
Type your answer here... Deffinately McCartney. Sir Paul, to be exact.

Enrique Iglesias! para todos magazine has already crowned him that and he has the maximum amount of number 1s on the latin charts and he is like a god so obviously its him.

"Parity" refers to the number of 1s in a given binary number. Odd parity means there are an odd number of 1s and even parity means that there are an even number of 1s. Parity bits are often used as a crude means of error detection as digital data is transmitted and received. For example, 0b11010100 has 4 1s in it, therefore, it has even parity. Two devices exchanging data must be set to the same parity. If both are set (strapped) for odd parity, for example, then the sending device must ensure that the number of bits in each word has an odd number of 1s. Likewise, the receiving device must be set to ensure it only receives words with an odd number of 1s. An odd parity bit is defined as a bit in the word which can be set to ensure odd parity. If the word already has an odd number of 1s, then the parity bit is not set. If the word otherwise has an even number of 1s, the parity bit is set to ensure an odd number of 1s. The same is true for even parity settings. One way is not necessarily better than the other in theory but, in practice, should observe the convention for the system in question. Many (if not most) devices provide a connector pin that can be strapped to define either even or odd parity.
1s + 1s + 1 = 2s + 1
