Boron. It's electron configuration is 1s22s22p1.
The element with the lowest atomic number that contains a half-filled d subshell at its ground state is scandium (atomic number 21). The electron configuration of scandium at ground state is [Ar] 3d^1 4s^2, where the 3d subshell is half-filled with one electron.
The element with the lowest atomic number that has a complete d subshell at its ground state is Titanium (element 22). In its ground state, Titanium's electron configuration is [Ar] 3d2 4s2, which means the 3d subshell is completely filled with 2 electrons.
Hydrogen is a non metal element. Atomic number of it is 1. It is the element with lowest atomic number.
Hydrogen, the element with the lowest atomic number.
The element with the lowest atomic number in period 3 is sodium (Na) with an atomic number of 11.
The element with the lowest atomic number that contains 10 p electrons in the ground state is neon. Neon has an atomic number of 10, and in its ground state, it has 2 electrons in the 1s orbital, 2 electrons in the 2s orbital, and 6 electrons in the 2p orbital.
The element with the lowest atomic number is hydrogen.
Hydrogen
The element with the lowest atomic number among the transuranium elements is neptunium, with an atomic number of 93. It is the first transuranium element produced synthetically in a laboratory setting.
The solid element with the lowest atomic number is lithium, with an atomic number of 3.
Hydrogen is a none metal element. atomic number of it is 1.
Hydrogen is the first element because it has the simplest atomic structure with just one proton in its nucleus. This makes it have the smallest atomic number, which determines the element's position in the periodic table.
