How do you find core and valence electrons? + Example - Socratic
2018年8月9日 · Refer to the explanation. For the main group (representative) elements, the valence electrons are the outermost (highest energy) "s" and "p" electrons, which make up the valence shell. The valence electrons participate in chemical reactions. The main group elements are the A groups, or groups 1,2,13-18. The core electrons are in the inner shells and do not …
What is the electron configuration of the neon atom?
2014年5月31日 · 1 Answer. Doc Croc. [2,8] or 1s22s22p6. Neon has atomic number 10, so a neon atom has 10 protons in its nucleus and therefore 10 electrons. The n=1 shell can only hold 2 electrons, so the remaining 8 electrons fill the n=2 shell. The more detailed version of the electronic configuration reflects the sub-shells in the n=1 and n=2 shells, where ...
What is the ground-state electron configuration of a neutral atom …
2017年6月13日 · 1s^(2)2s^(2)2p^6 or ["Ne"] or ["He"]2s^2 2p^6 First: Determine the number of electrons the element has. Neon has a total of then electrons. Second: KNOW YOUR ORBITALS!! Know how many electrons each orbital can hold and their order. (Refer to the following pictures as notes) Third: Write out the electron configuration: For Neon and other …
Valence Electrons - Chemistry - Socratic
Valence electrons are responsible for the reactivity of an element. They determine how "willing" the elements are to bond with each other to form new compounds. If the valence shell of an element is full, such as with a noble gas, then the element does not want to gain or lose an electron. For example, alkali metals, which all have a valency of ...
What ions are isoelectronic with neon? - Socratic
2017年4月25日 · You can get an ion that is isoelectronic with neon by either "OXIDATION" or "REDUCTION....." Neon has (Z=10) has 8 valence electrons, and a full valence shell. Looking at the Periodic Table, reduction gives the anions, F^-, O^(2-), N^(3-) as isoelectronic species.
Neon has 10 protons and 10 electrons. How are the electrons
2017年12月14日 · Since there are 10 electrons, the first two shells are filled (2 + 8 = 10 electrons) A more complex model considers each orbital. Orbitals fill in the order 1s,1p,2s,2p..... s orbitals hold 2 electrons, and p orbitals hold 6 electrons. We fill these orbitals until we have included all 10 electrons. 1s22p62s2. The first s orbital holds 2 electrons.
Valence Electrons - Chemistry - Socratic
The valence electrons are the electrons that determine the most typical bonding patterns for an element. These electrons are found in the s and p orbitals of the highest energy level for the element. Sodium 1s22s22p63s1. Sodium has 1 valence electron from the 3s orbital. Phosphorus 1s22s22p63s23p3. Phosphorus has 5 valence electrons 2 from the ...
How many valence electrons does Ne have? - Socratic
2016年10月29日 · Explanation: Neon, Z = 10, has eight valence electrons. This closed shell configuration makes neon supremely difficult to oxidize, and difficult to reduce. The inertness, the lack of reactivity, of this Noble Gas, is a function of its electronic configuration. Answer link. iOS.
How many electrons does neon have? - Socratic
2016年10月10日 · Explanation: The number of electrons is equal to the number of protons. The number of protons is equal to the atomic number ⇒ the number you see in the upper left corner. The atomic number of Neon is 10 ⇒ it has 10 protons and 10 electrons. The only difference is that electrons are negatively charged and protons are positively charged.
What are the numbers of the subatomic particles in neon?
2016年9月22日 · Well, for neon gas Z" the atomic number"=10 Given Z, we thus know that there are 10 positively charged protons in the neon nucleus. In order to attain electrical neutrality, there must also be 10 extranuclear electrons. We are not done yet because the nucleus also contains neutrons, massive nuclear particles of zero charge. The common isotope of Ne is ""^20Ne, …
