A Quote by Sam Kean
Atoms consist of a positive nucleus and negative electrons flying around outside it. Electrons closest to the nucleus feel a strong negative-on-positive tug, and the bigger atoms get, the bigger the tug. In really big atoms, electrons whip around at speeds close to the speed of light.

Atoms have a nucleus, made of protons and neutrons bound together. Around this nucleus shells of electrons spin, and each shell is either full or trying to get full, to balance with the number of protons-to balance the number of positive and negative charges. An atom is like a human heart, you see.
So if we're all quarks and electrons ..." he begins. What?" We could make love and it would be nothing more than quarks and electrons rubbing together." Better than that," I say. "Nothing really 'rubs together' in the microscopic world. Matter never really touches other matter, so we could make love without any of our atoms touching at all. Remember that electrons sit on the outside of atoms, repelling other electrons. So we could make love and actually repel each other at the same time.
The chemist in America has in general been content with what I have called a loafer electron theory. He has imagined the electrons sitting around on dry goods boxes at every corner [viz. the cubic atom], ready to shake hands with, or hold on to similar loafer electrons in other atoms.
If you had to sum up chemistry in one sentence, it might be this: Atoms need to have full shells of electrons to feel satisfied, and different elements steal, shed, or borrow different numbers of electrons to achieve a full shell.
From the results so far obtained it is difficult to avoid the conclusion that the long-range atoms arising from collision of alpha particles with nitrogen are not nitrogen atoms but probably atoms of hydrogen, or atoms of mass 2. If this be the case, we must conclude that the nitrogen atom is disintegrated under the intense forces developed in a close collision with a swift alpha particle, and that the hydrogen atom which is liberated formed a constituent part of the nitrogen nucleus.
No two electrons in the same state? That is why atoms are so unnecessarily big, and why metal and stone are so bulky.
The Universal mind is not only intelligence, but it is substance, and this substance is the attractive force which brings electrons together by the law of attraction so they form atoms; the atoms in turn are brought together by the same law and form molecules; molecules take objective forms and so we find that the law is the creative force behind every manifestation, not only of atoms, but of worlds, of the universe, of everything of which the imagination can form any conception.
Yes, Jenna, I love you with all my heart. And with my atoms and molecules and electrons and whatever further breakdown you require.
There are many ways of knocking electrons out of atoms. The simplest is to rub two surfaces together.
The most startling result of Faraday's Law is perhaps this. If we accept the hypothesis that the elementary substances are composed of atoms, we cannot avoid concluding that electricity also, positive as well as negative, is divided into definite elementary portions, which behave like atoms of electricity.
Not sense data or atoms or electrons or packets of energy, but purposes, interests, and meanings, constitute the underlying facts of human experience.
We have shown that it is possible to create a radioactivity characterized by the emission of positive or negative electrons in boron and magnesium by bombardment with alpha rays.
Thought is the primary energy and vibration that emanated from God and is thus the creator of life, electrons, atoms, and all forms of energy.
Indeed, nothing more beautifully simplifying has ever happened in the history of science than the whole series of discoveries culminating about 1914 which finally brought practically universal acceptance to the theory that the material world contains but two fundamental entities, namely, positive and negative electrons, exactly alike in charge, but differing widely in mass, the positive electron-now usually called a proton-being 1850 times heavier than the negative, now usually called simply the electron.
At two-tenths the speed of light, dust and atoms might not do significant damage even in a voyage of 40 years, but the faster you go, the worse it is--space begins to become abrasive. When you begin to approach the speed of light, hydrogen atoms become cosmic-ray particles, and they will fry the crew. ...So 60,000 kilometers per second may be the practical speed limit for space travel.
Atoms of Element 118 fill an outer shell with electrons, creating a special type of element called a noble gas. Noble gases are natural turning points on the table, ending one row and pointing to the next.
