Webb25 jan. 2024 · Valence electrons or outer-shell electrons are indicative of an atom’s reactivity. The presence of eight electrons in the valence shell of an atom imparts stability to that particular atom. To attain stability, atoms transfer or share electrons within themselves in such a way that they can satisfy the octet rule and attain noble gas … Webb29 dec. 2024 · We know, the electron configuration of the Argon atom is 1s 2 2s 2 2p 6 3s 2 3p 6, and valence electrons are those electrons found in the outer shell of an atom. This electron configuration of Argon shows that the outer shell of Argon has 8 electrons (3s23p6), hence, the number of valence electrons in the Argon atom is 8.

Webb6 mars 2024 · Valence electrons are the electrons contained in the outermost shell. If you look at the periodic table and at the period numbers, that is the number of valence electrons. If the number is larger than 10, subtract 10 so you get two valence electrons. Example: Oxygen is in the 16th period. Webb6 sep. 2024 · Find the element on the periodic table. The atomic number tells you how many electrons to draw in total. For example, potassium has 19 electrons Draw a small circle and write the symbol in the centre. This represents the nucleus Draw a circle around the nucleus. This is the first electron shell Add up to two electrons to the first electron … WebbAll that this means is that silicon has a core structure that is the same as neon, but then has four more electrons (3s2 3p2). It's just a short cut and it is commonly used. Furthermore, it is helpful because the outer electrons (3s2 3p2) are the valence electrons and these are the ones that are of most importance. 2 comments ( 10 votes) Upvote ctiw haven project
