The atoms of different elements have what
WebAt standard temperature and pressure, atoms for different elements in the solid state pack into different arrangements, which are called crystal systems. Some of these are much more efficient than others. For example, there are three variants of the cubic crystal system: primative, body-centered, and face-centered. WebExpert Answers.

WebAtoms, Elements, and Isotopes. An atom is the basic structure from which all matter is composed, in the same manner as a brick is the basic structure from which a wall is built. Although atoms are too small to be seen with our eyes, scientists have long had indirect evidence for the existence of atoms. We can now use the world's most powerful ... WebDalton's atomic theory states that chemical reactions involve combination, separation, or rearrangement of atoms. Dalton showed that matter always combined in fixed ratios based on mass or based on volume in the case of gases. Dalton's theory stated hat all atoms of a given element have exactly the same size and mass.
WebJan 17, 2024 · In simpler terms, the amount of time required for an element to lose half its mass is the element’s half-life. For example, an isotope of phosphorous ( 32 P) has a half-life of fourteen days. If we had twenty grams of this isotope, after fourteen days, we would be left with only ten grams, as half of the original mass would have decayed away. WebMolecules are the simplest unit of a covalent compound, and molecules can be represented in many different ways. Atoms are the smallest units of matter that still retain the fundamental chemical properties of an element. Much of the study of chemistry, however, involves looking at what happens when atoms combine with other atoms to form …
WebJul 20, 2024 · And electrons have a tiny negative charge. In an atom, the protons and neutrons hang out in the center, or nucleus. The electrons travel in a cloud around the nucleus. The cloud is split into layers called orbitals, where electrons are likely to be. Atoms of different elements have different numbers of protons, neutrons and electrons.
