WebApr 7, 2024 · In the case of carbon, the principal quantum number is 2, which means that there are two shells. The first shell (n=1) can hold a maximum of two electrons, which is why the 1s orbital is filled with two electrons in the carbon atom. The second shell (n=2) can hold a maximum of eight electrons, which is why the 2s and 2p orbitals are filled with ...

WebNov 14, 2012 · Carbon is a nonmetal in group 14 of the periodic table. Like other group 14 elements, carbon has four valence electrons. Valence electrons are the electrons in the outer energy level of an atom that are involved in chemical bonds. The valence electrons of carbon are shown in the electron dot diagram in the Figure below. [Figure1] WebAug 3, 2024 · A hydrogen atom has a valency of one as it only one electron in its outer shell. Total valence electron of CH 2 O= Valence electrons of Carbon + Valence electrons of Oxygen + Valence electrons of Hydrogen = 4+6+2*1 = 12 valence electrons of CH 2 O. Thus, CH 2 O has a total of twelve valence electrons that can help in drawing its Lewis structure. WebYttrium is a chemical element with atomic number 39 which means there are 39 protons in its nucleus. Total number of protons in the nucleus is called the atomic number of the atom and is given the symbol Z. The total electrical charge of the nucleus is therefore +Ze, where e (elementary charge) equals to 1,602 x 10-19 coulombs. cheap motels in simpsonville sc
