( 1/2 pt) Which group (alkali metal, halogen, noble gas, alkaline earth metal, or column number) or element matches the following descriptions?(a) Element: [A t] 4 s 2 … WebBecause the closest shell is filled, the third electron goes into the next higher shell. This shell has spaces for eight electrons, so that it takes an atom with 10 electrons to fill the first two levels. The next atom after neon, sodium, has 11 electrons, so that one electron goes into the next highest shell.
WebFor example, the 1st shell is made up of 1 subshell, s. It can therefore contain only 2 electrons. The 2nd shell is made up of 2 subshells, s and p. It can therefore contain 2+6=8 electrons. A complete table for the first four … WebJan 30, 2024 · The Principal Quantum Number (\(n\)) The principal quantum number, \(n\), designates the principal electron shell. Because n describes the most probable distance of the electrons from the nucleus, the larger the number n is, the farther the electron is from the nucleus, the larger the size of the orbital, and the larger the atom is.n can be any positive …
WebApr 15, 2024 · The closer the orbit is to the center of the atom, the lower its energy is. There are seven electron shells, and each higher level can hold more electron than the previous shell. Electrons naturally seek to occupy the lowest shell possible .So if there is space in a lower shell, an electron will drop down to occupy that space. WebSodium atoms have 11 protons and so 11 electrons: two electrons occupy the first shell. ...
WebThe first shell (closest to the nucleus) can hold two electrons. The second shell can hold 8 electrons. The third shell can hold 32 electrons. Within the shells, electrons are further …
WebThat is, the number of electrons in oxygen is 8. Therefore, an oxygen atom will have two electrons in the first shell and six in the 2nd shell. Therefore, the order of the number of electrons in each shell of the oxygen(O) atom is 2, 6. Electrons can be arranged correctly through orbits from elements 1 to 18. high waisted bikini ralph laurenWebValence electrons are the electrons in the outermost shell, or energy level, of an atom. For example, oxygen has six valence electrons, two in the 2s subshell and four in the 2p subshell. We can write the configuration of oxygen's valence electrons as 2s²2p⁴. Created by Sal Khan.
