What is the difference between an element and an atom?
2015年9月5日 · An atom is a thing; an element is a type of thing. An atom is a collection of protons, neutrons and electrons. A single, isolated atom in its neutral state has some number of protons, the same number of electrons and some number neutrons (about as many as protons for the lighter elements, up to about 50% more, for heavier elements).
What is the difference between an atom and an element?
2018年4月11日 · See below: Although one could claim that these two words are strongly connected they are widely different: An atom is the smallest component of an element, containing neutrons, protons and electrons, and makes up everything around us. An element is a substance in which all of the atoms have the same atomic (proton) number. It is also defined as a …
Visual explanation between Molecule vs Compound vs Element vs …
You either have an atom or a molecule. From Wikipedia: "A molecule is an electrically neutral group of two or more atoms ...". Furthermore, "Elements" can either refer to the species of an atom, e.g. $\ce{O}$. In this case it is not a molecule! Or it refers to the compound an element forms, e.g. $\ce{O2}$. In this case it is not an atom ...
What is an atom, element, molecule, and compound? What is an
2017年3月29日 · An atom is a particle of matter that characterizes a chemical element. It is the smallest part of ordinary matter. It is made from particles called protons, neutrons and electrons called the subatomic particles. An element is a substance that is made entirely of one type of atom. For example, the element sodium is made up of only sodium atoms.
What is the difference between O & O2 - Chemistry Stack Exchange
2017年1月10日 · Context is important. C is the atomic symbol for carbon and can represent not only the element, (but one or more) atoms of the element, as well as the element as it exists in the understood (implied) conditions. Same is true for O or N or actually any element. However, elemental O and N are both commonly found as diatomic molecules O 2 and N 2.
What is the definition of of 'compound', 'mixture', 'element' and ...
The term is also used to describe a collective of the same atom (element). A bar of gold (Gold being an 'element'; a chemical class) is said to be an element itself. Molecules are a group of atoms covalently bonded to each other (which can be considered a 'direct connection', if you will). The molecule can consist of atoms of the same element ...
What is the difference between an atom and an element?
2014年7月17日 · Good question! Elements are made up of atoms. Atoms are composed of protons, neutrons, and electrons. The number of protons in an atom determines what element it is. However, the number of neutrons can vary. For example, carbon atoms all have 6 protons. However, carbon-12 has six neutrons while carbon-13 has seven and carbon-14 has eight. …
How would you compare and contrast atoms, ions, and isotopes?
2015年11月29日 · Atoms, ions and isotopes are very closely related. An atom is the smallest uncharged unit of a substance. This means a substance is made up of only that very type of particle throughout. For example, air is a mixture of gases. It contains atoms, or strictly speaking, molecules, of various gases, mostly nitrogen and oxygen with small amounts of other gases …
What is the difference between an element, compound, and
2016年11月23日 · Elements have only one kind of atom but the others have more than one element chemically bonded. Elements are one kind of atom. If you have a piece of sodium, every atom is sodium, each having the same number of protons. A compound has more than one element chemically bonded. This bond is a link between the nuclei of the atoms and the …

2018年1月30日 · Atoms and molecules are objects . A compound isn't an material object, but a kind of substance. An element is a type of sub-component in a compound not associated with a specific kind of substance. Atoms are very small, invisible objects having a tendency to aggregate among themselves to form "clusters". These clusters, or stable groups of atoms, have been …
