Sn is in group 4 so has 4 electrons in the outer shell (draw<span> these as dots) Add 1 more electron from each bond to F (+6) </span>
<span>element X has 62 neutrons
The atomic number of an atom is the number of protons that atom has. And the mass number of an atom is the sum of the number of protons and neutrons an atom has. So to determine the number of neutrons, simply subtract the atomic number from the mass number. So
89 - 27 = 62
So element X has 62 neutrons.</span>
Answer: THIS IS THE EXACT ANSWER
Three effective techniques Ann could use to learn all the US states and their state capitals are visualization and association, creating a mnemonic device, and rhyming. She could learn some of the states and their capitals by visualizing her own experiences in or about the state. As an example of association, if Ann visited Idaho last winter to see her twin brothers, she might think “I went to Idaho to visit the boys” (sounds like Boise). By employing association, she connects her own life experience to the information she wants to remember to make recalling the information easier. To remember the capital of Washington, Ann might create a mnemonic device like “George Washington went to the Olympics” (Washington’s capital is Olympia). Mnemonic devices organize information to encode it in a way that helps with recall. To effectively use rhyming, she might remember Michigan is a northern state and use “Reindeer prancing in Lansing.” Rhyming provides a cue that helps with recall. All three of these techniques work in the encoding and retrieval stages.
