Which element has one 2s electron?
Lithium
What is the highest occupied energy level in the element Beryllium?
2s
Which element has only 3 orbitals?
The element with only 3 orbitals is lithium (Li). The electron configuration is 1s^2 2s^1, indicating that it has one electron in the 2s orbital.
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 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.
Which element has 1s 2 2s 2 2p 6 3s 1 as its electron configuration?
The element with the electron configuration 1s2 2s2 2p6 3s1 is sodium (Na).
What element has an electron arrangement of 2882?
This chemical element is calcium (Ca).
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?
The element with 2 electrons in the 1s sub-level, 2 electrons in the 2s sub-level, and 2 electrons in the 2p sub-level is carbon (Atomic number: 6).
What is the full electron configuration for the element Carbon?
The full electron configuration for Carbon is 1s^2 2s^2 2p^2. This means that Carbon has 6 electrons distributed in the 1s, 2s, and 2p orbitals.
What is the element with a valence electron configuration of 2s22p3?
The element with a valence electron configuration of 2s22p3 is phosphorus (P). This configuration indicates that phosphorus has 5 valence electrons, which are distributed in the 2s and 2p orbitals.
What element has 2 electrons in the 1s sublevel and 4 electrons in the 2s level?
An element cannot have 4 electrons in the 2 s level. The s subshell can hold only TWO electrons. Carbon has 4 electrons in the 2p level, however, if that's what you meant.
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)
