16 electrons would fill up the first four shells in an atom: 2 electrons in the first shell, 8 electrons in the second shell, 4 electrons in the third shell, and 2 electrons in the fourth shell.
A selenium atom typically contains 34 electrons distributed in different shells around the nucleus. The electrons are arranged in energy levels or shells, with the first shell holding a maximum of 2 electrons, the second shell holding up to 8 electrons, the third shell holding up to 18 electrons, and the fourth shell holding up to 6 electrons for selenium.
There are four energy shells. The levels go: 1s2, 2s2, 2p6, 3s2, 3p6, 4s2, 3d10. This is because there are 30 electrons.
Four atoms with 1 electron in their outermost shells will bond with one atom that has 4 electrons in its outermost shell. This results in the formation of a stable compound with each atom achieving a full outer shell of electrons through sharing or transferring of electrons.
An atom with four full electron orbits is typically associated with the element Xenon (Xe), which has an atomic number of 54. In its ground state, Xenon has a complete set of electron shells (orbits) filled with electrons, including the first four energy levels. These filled shells contribute to its stability and inertness, characteristic of noble gases.
how many energy levels are filled in a krypton atom They have four levels. You always put 2 in the first. 8 in the second. 18 in the third. And I believe you are able to put 36 in the fourth level, but correct me if I'm wrong about the fourth level.
The electron configuration of iron is [Ar]3d64s2. The electron shells contain 2, 8, 14 and 2 electrons.
An iodine atom has 46 core electrons. Core electrons are the inner electrons that are not involved in chemical bonding. In the case of iodine, the core electrons would include the 36 electrons found in the first four electron shells.
Germanium has four electron shells. Its electron configuration is [Ar] 3d10 4s2 4p2, indicating it has electrons in the first four energy levels (shells). The first shell can hold up to 2 electrons, the second up to 8, the third up to 18, and the fourth shell holds the remaining electrons.
No, having four valence electrons does not determine whether an atom is an anion. An anion is formed when an atom gains electrons to have a negative charge. If the atom with four valence electrons gains four more electrons, it would become an anion.
Carbon has two electrons in its inner shell and four in its outer shell.
Shell 1: Two electrons Shell 2: Eight electrons Shell 3: Eight electrons Shell 4: Eighteen electrons
