Web18 aug. 2024 · Solids (like liquids) are not very compressible due to the lack of space between molecules If the molecules in a solid adopt a highly ordered packing arrangement, the structures are said to be crystalline Due to the strong intermolecular forces between neighboring molecules, solids are rigid. Cooling a gas may change the state to a liquid WebAn atom consists of two regions. The first is the tiny atomic nucleus, which is in the center of the atom and contains positively charged particles called protons and neutral, uncharged, particles called neutrons. The second, much larger, region of the atom is a “cloud” of electrons, negatively charged particles that orbit around the nucleus. teglet tool package ログイン

By definition, any two atoms with an identical number of protons in their nuclei belong to the same chemical element. Atoms with equal numbers of protons but a different number of neutrons are different isotopes of the same element. For example, all hydrogen atoms admit exactly one proton, but isotopes exist with no neutrons (hydrogen-1, by far the most common form, also called protium), one neutron (deuterium), two neutrons (tritium) and more than two neutrons. The kno… Web5 mei 2024 · An atom is a building block of matter that cannot be broken apart using any chemical means. Nuclear reactions can alter atoms.
