Image result for What happens to sodium chloride when it dissolves in water
Explanation: On addition to water the Na+ section of NaCl is attracted to the oxygen side of the water molecules, while the Cl- side is attracted to the hydrogens' side of the water molecule. This causes the sodium chloride to split in water, and the NaCl dissolves into separate Na+ and Cl- atoms
Answer:
An ionic bond is an attraction between ions of opposite charge in an ionic compound.
Answer:
There are four ways to find the charge of an element:
Use the periodic table. The usual charge of an element is common to its group. ...
Use a chart. ...
For a single atom, the charge is the number of protons minus the number of electrons.
Find the charge by balancing charge in a compound
E ground pushes you forward. But that interaction is friction. Reduce friction and it doesn't matter how strong your legs are, the surface is incapable of pushing you accordingly. The coefficient of static friction is very low so it is easy to slide your foot rather than push.
The answer is it tends to be more negative down a group. This is because as you go down the periodic table, the elements have more electron shells in their atoms. This makes the outermost shells less attracted to the nucleus due to their greater distances from the nucleus. Therefore, these shells are less likely to attract electrons (hence lower electron affinity) and are even more likely to lose electrons from their outer electron orbits.
