An atom is the smallest unit of ordinary matter that forms a chemical element. Every solid, liquid, gas, and plasma is composed of neutral or ionized atoms. Atoms are extremely small, they usually are around the size of 100 picometers across. They are so small that accurately predicting their behavior using something called classical physics, if they were tennis balls, for example, It wouldn't be possible for them to exist due to quantum physics. Every atom is composed of a nucleus and one or more electrons bound to the nucleus. The nucleus is made of one or more protons and a number of neutrons. Only the most common variety of hydrogen has no neutrons. More than 99.94% of an atom's mass is in the nucleus. The protons have a positive electric charge, the electrons have a negative electric charge, and the neutrons have no electric charge. If the number of protons and electrons are equal, then the atom is electrically neutral. If an atom has more or fewer electrons than protons, then it has an overall negative or positive charge, FYI these kind of atoms are called "Ions"
In this excerpt from <em>A World Without Collisions</em>, Sam describes how he dreams the world to be in the future. I think his main idea has good intentions, he feels sorry for those who get hurt in "learning how to live life". He also seems to think that everybody should take control of their lives and don't be just a victim on everything that happens. This way of thinking has good intentions, but it is not always realistic or even easy to do.
First of all, unexpected things happen in life and some are pretty big and sad, and we do not control everything that happens around us. It is true that we can try and control our emotions in order to feel better, but not what happens outside our bodies. The thing is also, we can chose not to be victims, but it is healthy sometimes to embrace the bad feelings to because only by accepting our sadnesses or pains is that we will be able to move forward. If we deny this bad feeling, our bodies will eventually speak for us and show us that we have been hiding important issues that we should face. I agree, we should "dance life like champions", but doing so is also embracing the bad feelings, connecting with them, and get pass through them. We ARE going to get hurt "in all that bumping" and it is ok.
No, grandparents is a common noun, therefore you don't capitalize it. It would be different if you had the names of the grandparents. Like if your grandma is named Martha. You would have to capitalize their name since it is a proper noun
