WebSo, oxygen has eight positive particles plus eight negative particles. Think of this as 8+(-8) or 8-8. Eight minus eight equals zero, which is neutral. Basically, a "neutral atom" is an atom that has the same amount of protons as it does electrons. Later you will learn about ions, which have unequal amounts of protons and electrons. WebEach shell can contain only a fixed number of electrons: the first shell can hold up to two electrons, the second shell can hold up to eight (2 + 6) electrons, the third shell can hold …
Sodium - Element information, properties and uses
WebSince 1s can only hold two electrons the next 2 electrons for sodium go in the 2s orbital. The nex six electrons will go in the 2p orbital. The p orbital can hold up to six electrons. We'll put six in the 2p orbital and then put the remaining electron in the 3s. Therefore the sodium electron configuration will be 1s 2 2s 2 2p 6 3s 1. Web1. How many valence electrons are in a sodium atom? Sodium has 1 valence electron.:D SMILE 2. how many valence electrons does AI have Answer: Aluminum (Al) has three valence electrons flo lady on insurance ads

WebJul 1, 2024 · On the left, a sodium atom has 11 electrons. On the right, the sodium ion only has 10 electrons and a 1+ charge. Now, let's consider chlorine atom, Cl: 1s22s22p63s23p5 Only one more electron is needed to achieve an octet in chlorine’s valence shell. When a chlorine atom gains an electron, its outermost principal energy level achieves an octet. WebAug 3, 2016 · The thing to remember about main-group elements, which are those elements located in groups 1, 2, and 13 through 18, is that their group number tells you the number … WebA neutral atom of Carbon-12 contains six protons, six neutrons, and six electrons; therefore, it has a mass number of 12 (six protons plus six neutrons). Neutral carbon-14 contains six protons, eight neutrons, and six … floleather stinson twitty
