Webatomic number and charge. Determine why the following statement by a chemist probably is not true. "I have three samples of three different elements. The first sample is potassium, with 19 protons and 19 neutrons in each atom; it is the lightest. The second is also potassium with 18 protons and 22 neutrons in each atom; it is slightly heavier. WebAnswer (1 of 8): I see, guys answering the question applied a fair amount of effort, but all these insights didn’t satisfy me completely. Here we have, actually, three questions compressed into one: 1. Why an atom doesn’t …
Why is an atom neutral? - Reimagining Education
Web8 de feb. de 2024 · Atoms are electrically neutral because they have equal numbers of protons (positively charged) and electrons (negatively charged). If an atom gains or loses one or more electrons, it becomes an ion. If it gains one or more electrons, it now carries a net negative charge, and is thus "anionic. a unit of mass used to express atomic and … WebSolution. Verified by Toppr. Almost all of the mass in an atom is made up of the protons and neutrons in the nucleus. Protons are positively charged and neutrons have no charge on them. Because the nucleus is only made up of protons and neutrons it is positively charged. Was this answer helpful? spring mvc header

WebSo an atom as a whole is electrically neutral. When one or more electrons is stripped away from an atom, it becomes positively charged. Some atoms can attract additional electrons so they become negatively charged. Atoms which are not electrically neutral are called ions. One can collect electric charge by transferring electrons.
