1. What kinds of metals are REALLY reactive? why?
2. What kinds of non-metals are REALLY reactive? why?
3. What group on the periodic table doesn’t react at all? why?

Answers

Answer:

1. Alkali metals (group 1)

2. halogens (Group 17)

3. noble gasses (group 18)

Explanation:

1. alkali metals only have one valence electron meaning that they really want to lose that one valence electron to get a full octet.

2. halogens have 7 valence electrons meaning that they just need to gain 1 to get a full octet.

3. Nobel gasses already have a full octet meaning that they don't want to react. (atoms only react to get a full octet)

I hope this helps.  Let me know if anything is unclear.

And of course it would happen, as the end to such a day, that just as the sun went down the back of the mountain and the long twilight began, she noticed that Rollie was not around.Tense with exasperationshe would simply explode if Mother got goingshe began to call him in a carefully casual tone: "Here, Rollie! He-re, boy! Want to go for a walk, Rollie?" Whistling to him cheerfully, her heart full of wrath at the way the world treated her, she made the rounds of his haunts; the corner of the woodshed, where he liked to curl up on the wool of Father's discarded old windbreaker; the hay barn, the cow barn, the sunny spot on the side porchno Rollie.Perhaps he had sneaked upstairs to lie on her bed where he was not supposed to gonot that she would have minded! That rule was a part of Mother's fussiness, part too of Mother's bossiness. It was her bed, wasn't it? But was she allowed the say-so about it? Not on your life. They told her she could have things the way she wanted in her own room, now she was in her teens, buther heart raged against the unfairness as she took the stairs stormily, two steps at a time, her pigtails flopping up and down on her back. If Rollie was on her bed, she was just going to let him stay right there, and Mother could shake her head and mumble all she wanted to. But he was not there. The bedspread and pillow were crumpled, but not from his weight. Earlier that afternoon, she had flung herself down to cry there. And then she couldn't. Every nerve in her had been twanging, but she couldn't cry. She could only lie there, her hands doubled up hard, furious that she had nothing to cry about. Not really. She was too big to cry just over Father's having said to her severely, "I told you if I let you take the chess set you were to put it away when you got through with it. One of the pawns was on the floor of our bedroom this morning. I stepped on it. If I'd had my shoes on, I'd have broken it."Well, he had told her to be sure to put them away. And although she had forgotten and left them, he hadn't forbidden her ever to take the set again. No, the instant she thought about that, she knew she couldn't cry about it. She could be, and she was, in a rage about the way Father kept on talking, long after she'd got his point, "It's not that I care so much about the chess set," he said, just leaning with all his weight on being right, "it's because if you don't learn how to take care of things, you yourself will suffer for it later . . . . If we . . ." on and on, preaching and preaching.Which statement most accurately describes the girl's feelings? A. She is angry because the whole world seems against her. B.
