The dissociation of NaCl into Na+ and Cl is a physical change, rather than a chemical reaction (which would necessitate the formation of new products).It seems as if covalent bonds have been covered well in other answers, but ionic bonds have been left out.Another pattern can be noticed between elements to the far left of the table (metals) and those on the far right (nonmetals). For instance, a very common compound that fits this bill is sodium chloride, NaCl (table salt). While chlorine has 7 electrons in its valence shell and wants to fill that with an additional electron (very electronegative), sodium has an extra electron that it is willing to give up (therefore, it is electropositive).
Polarisers are fun, and display quantum mechanics effects that can confuse people. Light, and all electromagnetic waves, can be considered to have two parts, with one that is a quarter wave behind the other. If the two parts have their electric fields aligned then we have a linear polarisation (and there are many directions of alignment).
In Australia, the belief now is that interest rates are on hold until early next year at least. Most think rates will go up, when they do mobve. But with inflation sitting below the Reserve Bank’s targeted ceiling of three per cent and the economy performing a Goldilocks act neither too hot nor too cold there does not appear to be any reason for undue haste..
In the meantime, regardless of which side of the path his bird feeders are on, I will stop with my kids in tow to chat with Bruno, his family and his friendly dogs. We help him refill those feeders and we talk about the birds, the deer, and the sheer beauty of what we sit and wake up to every morning. A few doors down, my own two bird feeders will stay on the wild side, as they have been for the last three years so that the birds can enjoy the security of the trees and shrubs and are not tempted to fly any closer to the large windows of the house than necessary..
Health is important and cannot be understated. Kyrie and Love have tons of history with nagging injuries that keep them out for weeks at a time. Let just look into our crystal ball and pretend that they both can play at least 90% of the remaining games AND that they are healthy for all the playoff games (not unreasonable).
