Which element has four valence electrons.

The outermost shell is the valence shell of the element. The elements in groups have similar electronic configuration of the valence shell. ... Therefore, the element that has total of three shells and four electrons in valence shell is Silicon (Si). The explanation for the incorrect option:Carbon is a group 14 element. All group 14 elements have 4 valence electrons. Thus, carbon has 4 valence electrons.Element A, with seven valence electrons, is more reactive compared to element B, which has four valence electrons.The correct answer is option A. Reactivity in elements is largely determined by the number of valence electrons, which are the electrons in the outermost energy level of an atom.Elements with fewer valence electrons tend to be more reactive because they have a greater tendency to ...Generally, metals will lose electrons to achieve a valence shell of eight electrons. Non-metals tend to gain electrons to obtain eight electrons. Certain atoms tend to have a certain number of bonds to meet the octet rule. For example, carbon will almost always have four bonds. Nitrogen will almost always have three bonds plus a lone pair.

Carbon's ability to form bonds with four other atoms goes back to its number and configuration of electrons. Carbon has an atomic number of six (meaning six protons, and six electrons as well in a neutral atom), so the first two electrons fill the inner shell and the remaining four are left in the second shell, which is the valence (outermost ...The electronic configuration of each element is decided by the Aufbau principle which states that the electrons fill orbitals in order of increasing energy levels. The equation is: 1s<2s<2p<3s<3p<4s<3d<4p<5s<4d<5p<6s<4f<5d<6p<7s<5f<6d<7p.

Once you know an element's electron configuration, finding its number of valence electrons is quite simple (except, of course, for the transition metals.) If you're given the configuration from the get-go, you can skip to the next step.For main group elements (i.e s-block and p-block elements), the valence electrons are the electrons present in the outermost orbit. But for most of the transition and inner transition elements, the valence electrons are the electrons present in the shells outside the noble gas core.For example, each atom of a group 14 element has four electrons in its outermost shell and therefore requires four more electrons to reach an octet. These four electrons can be gained by forming four covalent bonds, as illustrated here for carbon in CCl 4 (carbon tetrachloride) ... 4 valence electrons/atom × 1 atom} \hspace{6px}= \phantom{1}4\\The valence electrons for main group elements are those with the highest n level. For example, gallium (Ga, atomic number 31) has the electron configuration [Ar]4s 2 3d 10 4p 1, which contains three valence electrons (underlined).
