Science As Inquiry: I- Abilities necessary to do scientific inquiry- Form questions about objects, organisms, and events in the environment- Conduct investigations- Physical Science: II- Properties of objects and materials- Objects are made of one or more materials, such as paper, wood, and ...
If you know where a certain element sits in the table, and you know a little bit about the properties of the elements above, below, and either side, you can often figure out what the properties of that element will be.How do atoms make molecules and compounds? Atoms are a bit like ...
Atomsare the foundation of matter, which is everything that makes up the universe around us. Each kind of atom makes up a pure substance called an element. You may have heard of oxygen, lead, and gold. Well, these are all examples of elements. Can you believe that a pure gold ...
Atoms are the basis of all the elements in the universe, the building blocks of all visible matter, and the secret to nuclear power.
Atoms (原子) are all around us. They are the bricks of which everything is made. Millions of atoms are held in just one grain of salt, but in spite of their small size they are very important. The way an everyday object acts depends on what kind of atoms ...
Each electron has a charge of -1(that is, they are negatively charged). Electrons are distributed around the volume of the atom of which they are a part in 'shells', 'orbits' or 'energy levels', which are all different terms used to describethe electronic structure of atoms, an importan...

Neutrons are similar in size to protons, with an amu of 1.00867, and also inhabit the nucleus of atoms. The number of neutrons in an atom in an element's most stable configuration is usually greater than the number of protons, with this disparity becoming larger as atomic number increases....
In a single atom, electrons can occupy specific energy levels. When multiple atoms bond, the electrons are shared between them. But because the atoms are now interacting, the energy levels shift around. In a solid, trillions and trillions of atoms interact with each other. Their individual ...
