volcanoes are necessary because:
fertile is another advantage of volcanic activity."In places like Japan,Indonesia,Philippines,Hawaii,volcanic material mixed in with the soil provides a lot of important nutrients
Answer: Option (b) is the correct answer.
Explanation:
Atomic number of magnesium is 12 and its electronic distribution is 2, 8, 2. Whereas atomic number of sulfur is 16 and its electronic distribution is 2, 8, 6.
So, in order to attain stability a magnesium atom needs to lose its 2 valence electrons and a sulfur atom needs to gain two electrons to completely fill its octet.
Hence, magnesium on losing two electrons will acquire a +2 charge and thus, it becomes a cation. On the other hand, sulfur on gaining two electrons will acquire a -2 charge and thus, sulfur will become an anion.
Thus, we can conclude that in the reaction between magnesium and sulfur, the magnesium atoms become cations.
Answer:A star topology is designed with each node (like workstations, printers, laptops, servers etc.) connected directly to a central device called as a network switch. Each workstation has a cable that goes from its network card to a network switch.
Most popular and widely used LAN technology Ethernet currently operates in Star Topology.
