2014年1月20日 · It is an ionic bond created by an attraction between the +1 sodium cation and the -1 chlorine anion. Sodium which has an electron configuration of 1s^2 2s^2 2p^6 and 3s^1. The sodium will readily give away the one electron in the 3 s orbital in order to stabilize the outer shell and become like the noble gas neon. In doing this the sodium takes on a +1 charge with …

2018年5月15日 · Yes Ionic bonds usually occur between metals and nonmetals Sodium (Na), a metal, and chloride (Cl), a nonmetal, form an ionic bond to make NaCl.

2010年11月19日 · Now, in Pauling's theory, the ionic character can be calculated from the difference in (Pauling) electronegativities between the atoms. So to begin with, there's a sliding scale, and really no such thing as a purely ionic bond, nor any such thing as a purely covalent bond, except for a homonuclear diatomic, where the electronegativities are equal.

2014年12月1日 · The bond holding NaCl together is ionic in nature, i.e. the Na atom 'gives' an electron to the chlorine atom resulting in two charged ions which are attracted by the Coulomb interaction. In HCl the bonding is covalent, i.e. the outer electrons are shared. Hence NaCl is an ionic compund, and HCl is not.

2012年10月17日 · In summary, in gaseous NaCl, the bond can be considered as either very polar covalent or ionic, depending on the purpose. Nature does not recognize chemical bonds and in gaseous NaCl, the lowest energy pathway for dissociation is to Na• + Cl• rather than Na+ + Cl– due to the energy cost of removing the electron from sodium being larger ...

2014年2月25日 · A sodium atom donates a valence electron to a chlorine atom to form a sodium ion and a chloride ion. A sodium atom has the electron configuration 1s² 2s²2p⁶ 3s. It can gain a noble gas (s²p⁶) configuration by losing the 3s electron. A chlorine atom has the electron configuration 1s² 2s²2p⁶ 3s²3p⁵. It can achieve a noble gas configuration by gaining an …

2008年3月26日 · Homework Statement NaCl is an ionic compound, but chlorine and silicon are joined by covalent bonds in SiCl4 A. Use Table 5.4 (page 229 of your text) to determine the electronegativity difference between chlorine and sodium, and between chlorine and silicon. What values did you calculate...

2017年2月22日 · Why? Because of electrostatic attraction between unlike charges. And of course, in an ionic solid (say "sodium chloride"), an isolated cation, a sodium ion, is BOUND ELECTROSTATICALLY to EVERY OTHER CHLORIDE ANION in the lattice. The attraction/repulsion follows "Coulomb's Law", and is thus strongest between a close-packed …

2018年6月18日 · One molecule of sodium chloride is composed of one sodium (Na) atom and one chlorine (Cl) atom as indicated by the chemical formula. As sodium is a metal and chlorine is a non-metal, these two atoms are joined together by an ionic bond to form a sodium chloride molecule. For more information on chemical formulae and molecular structures, you can refer …

2008年9月3日 · 1. Although we have to write sodium chloride as NaCl, we realize that NaCl is an ionic compound and contains no molecule. Explain. I kind of came up with an idea that sodium is a positive charge and chlorine is a negative charge. Is this the reason why they have no molecules? Is that what the question is asking? Thanks.
