To determine this look at the periodic table. The larger the atom, the farther its valence electrons are from the nucleus. Therefore, potassium's valence electrons have the highest energy.
The highest occupied energy level in potassium is the fourth energy level because potassium has 19 electrons, occupying the first three energy levels (with 2, 8, and 8 electrons, respectively) and the remaining electron is in the fourth energy level.
The number of electrons in the highest occupied energy level of an element in Group 15 is 5. Group 15 elements have 5 valence electrons, which occupy the highest energy level.
7 electrons would be in the highest occupied energy level of a 7A element. Group 7A elements have 7 valence electrons, which occupy the highest energy level of the atom.
The highest sublevel that Promethium can have is 4f. It is possible for 14 electrons to be placed around Promethium, since the elements in this sublevel each have 7 orbitals.
The highest number of electrons in an atom is 116, as Ununhexium has an atomic mass of 292 it has 116 protons and 116 electrons as well as 176 neutrons.
The highest occupied energy level in potassium is the fourth energy level because potassium has 19 electrons, occupying the first three energy levels (with 2, 8, and 8 electrons, respectively) and the remaining electron is in the fourth energy level.
Osmium is the solid element that has the highest density. Opposite of osmium is hydrogen which has the lowest density.
The number of electrons in the highest occupied energy level of an element in Group 15 is 5. Group 15 elements have 5 valence electrons, which occupy the highest energy level.
7 electrons would be in the highest occupied energy level of a 7A element. Group 7A elements have 7 valence electrons, which occupy the highest energy level of the atom.
Because an atom of element has the same number of electrons as of protons and the number of protons in an atom is the same as the atomic number of the atom, the answer to this is whichever element has the highest atomic number yet synthesized.
The highest sublevel that Promethium can have is 4f. It is possible for 14 electrons to be placed around Promethium, since the elements in this sublevel each have 7 orbitals.
The highest number of electrons in an atom is 116, as Ununhexium has an atomic mass of 292 it has 116 protons and 116 electrons as well as 176 neutrons.
The highest energy level is called the "electronegativity".
Fluorine is the strongest oxidizing agent among lithium, fluorine, and hydrogen. It has the highest electronegativity and readily accepts electrons to form fluoride ions.
8: that's the meaning of "octet".
C22h46
The element in period 4 of the Periodic Table with the highest electronegativity is krypton (2.96). The period 4 element with the lowest electronegativity is potassium (0.82).
