Explanation:
A chemical bond which is formed in between positively charged atoms when there is sharing of free electrons in a lattice of cations is known as a metallic bond.
In a pure metal, atoms are surrounded by free moving valence electrons which move from one part of metal to another.
Thus, we can conclude that pure metals are held together by metallic bonds due to attraction between mobile valence electrons and positively charged metal ions.
Answer:
Magnesium is a naturally ubiquitous; (appearing & found evrywhere) element and has three naturally occurring stable isotopes, 24Mg, 25Mg and 26Mg, with relative abundance of 78.99%, 10.00% and 11.01%, respectively.
However, they differ only because a 24Mg atom has 12 neutrons in its nucleus, a 25Mg atom has 13 neutrons, and a 26Mg has 14 neutrons.
Explanation:
North Carolina winter weather evolves from complex meteorological patterns that are difficult to forecast, and which lead to considerable variability in weather conditions across the state. As a result, the frequency and intensity of winter weather events are highly variable and dependent upon large (synoptic) and small (mesoscale) scale atmospheric patterns.
The jet stream is a narrow band of strong winds in the upper atmosphere. In winter, it separates cold, Arctic air masses from warmer, continental air masses. Certain regions of the jet are also favorable for storm development, while others are not.<span>The orientation and location of the jet stream has large implications on the weather year-round, but even more so in winter because the jet stream is stronger due to a large temperature contrast from the north to south.
i know nothing about science but then it just comes to me and i get it right.
