How can an atom be stable
WebCovalent bonding. A covalent bond forms when two non-metal atoms share a pair of electrons. The electrons involved are in the outer shells of the atoms. An atom that shares one or more of its ... Web4 de out. de 2024 · We all know that hydrogen becomes stable by completing duplet and helium is stable since its valence shell has completed the duplet Still, other elements don't behave like that. I want to know that why aren't elements like magnesium, beryllium etc, with two valence electrons be unreactive like helium atom, or why can't other elements …

WebForms of the same atom that differ only in their number of neutrons are called isotopes. Together, the number of protons and the number of neutrons determine an element’s mass number: mass number = protons … Web25 de ago. de 2024 · The relationship between the number of protons and the number of neutrons in stable nuclei, arbitrarily defined as having a half-life longer than 10 times the age of Earth, is shown graphically in Figure 21.2. 2. The stable isotopes form a “peninsula of stability” in a “sea of instability.”.
WebWhen a stable atom gains or loses an electron, it becomes an ion. For example, when chlorine takes an electron from sodium, and sodium gives that electron to chlorine, they … WebOctet Rule. The Octet Rule requires all atoms in a molecule to have 8 valence electrons--either by sharing, losing or gaining electrons--to become stable. For Covalent bonds, atoms tend to share their electrons with …
