Atoms are the purest form of matter. They consist of protons, neutrons, and electrons. The periodic table lists all of the different types of atoms that are known to exist and are known as elements. Answer and Explanation: An atom that has more protons than electrons is called a cation. ...
The actual mass of an atom at rest is very difficult to measure, as even the most massive of atoms are too light to express in conventional units. As such, scientists often use the unified atomic mass unit (u) – also called dalton (Da) – which is defined as a twelfth of the mass...
and electrons. Atoms that have either a deficit or a surplus of electrons are called ions. Electrons that are farthest from the nucleus may be transferred to othernearby atomsor shared between atoms. By this mechanism, atoms are able to bond into molecules and other types of chemical compounds...
Every element is made of atoms- piles of paper clips. All atoms of any element are the same- all the paper clips in the pile are the same size and color. Atoms of different elements are different (size, properties)- like different sizes and colors of paper clips. ...
Most atoms have three different subatomic particles inside them: protons, neutrons, and electrons. The protons and neutrons are packed together into the center of the atom (which is called the nucleus) and the electrons, which are very much smaller, whizz around the outside. When people draw ...
If any matter is smaller or larger than an atom, it is not an atom. Molecules and compounds may contain atoms, but they are not atoms themselves. Some examples of molecules and compounds are salt water (NaCl) and ethanol. Electrically charged atoms that conduct electricity are called ions, ...
When different types of atoms combine, the result is called a compound. How Atoms Combine The propensity for an atom to combine depends on the number of electrons it has in its outer shell. Every shell has eight spaces for electrons except the first shell, which has only two spaces. If ...
All atoms consist of three particles, calledprotons,neutronsandelectrons. These are calledsub-atomic particles. They are (obviously) much smaller than the atom itself and have the following properties: Particle Symbol Mass (atomic mass unit u) ...
