and governments try to fund a wide breadth of scientific work, so they have to accept that studies will not usually go as advertised. Scientists pivot, finding new directions and reaching new opinions, and government grant agencies don’t have the interest or the staff to police them for it...
Atoms stick together protons, neutrons, and electrons, and protons and neutrons are made of stuck-together quarks in turn. And while atoms, despite the name, aren’t indivisible, you might think that if you look small enough you’ll find indivisible, unchanging pieces, the smallest building-bl...
Theproperties and characteristics of static electricityrevolve around atoms and the positive and negative charges that they create. All physical matter, including the human body, is made of atoms, which consist of three basic particles — protons, electrons, and neutrons. When our bodies rub agains...
Each element is unique because each element's atoms are unique, which different numbers of protons, neutrons, and electrons in the atom. These unique atomic structures give each element its unique characteristics, such as its texture,...
It can be tempting to imagine the world in terms of lego-like building-blocks. Atoms stick together protons, neutrons, and electrons, and protons and neutrons are made of stuck-together quarks in turn. And while atoms, despite the name, aren’t indivisible, you might think that if you loo...
Select the correct answer. Carbon-12 is the most common isotope of carbon. It has 6 protons, 6 neutrons, and 6 electrons. Of its 6 electrons, 4 are valence electrons. How many covalent bonds can a carbon atom form? A. ...
