Ions are more stable than atoms. give reason
Web5 okt. 2024 · An ion is defined as an atom or molecule that has gained or lost one or more of its valence electrons, giving it a net positive or negative electrical charge. In other words, there is an imbalance in the number of protons (positively charged particles) and electrons (negatively charged particles) in a chemical species. WebWhen an atom is attracted to another atom because it has an unequal number of electrons and protons, the atom is called an ION. If the atom has more electrons than protons, it is a negative ion, or ANION. If it has more protons than electrons,it is a positive ion. What ...

Web28 mei 2024 · Give reasons for the following: H2^+ and H2^- ions have same bond order but H2^+ ions are more stable than H2^-. askedJan 12, 2024in Chemistryby … Web7 mrt. 2024 · Answer Verified 255.9k + views Hint: Atoms are electrically neutral because they have equal numbers of protons (positively charged) and electrons (negatively charged). If an atom gains or losses one or more electrons, it becomes an ion. Complete answer: We know that an atom consists of the three subatomic particles.
Web2 dagen geleden · The general rule-of-thumb is that if a charge is very localised (all concentrated on one atom) the ion is much less stable than if the charge is spread out over several atoms. Applying that to … Web18 aug. 2024 · atom: The basic unit of a chemical element. Atoms are made up of a dense nucleus that contains positively charged protons and uncharged neutrons. The nucleus is orbited by a cloud of negatively charged electrons. bond: (in chemistry) A semi-permanent attachment between atoms — or groups of atoms — in a molecule.
Web21 mei 2016 · If two similar sized atoms have different electronegativity values, the atom with higher electronegativity holds the electrons more tightly, and thus is more stable. Example: hydroxide vs azanide (NH2-). If two atoms have different sizes (down the periodic table), the larger atom has electrons more spread out and thus is more stable. WebCations and anions can be unstable for the simple reason that charge separation costs energy. There are a few cases in which these ions are really quite stable -- alkali cations such as Na + and halide anions such as Cl-come to mind -- but here we are interested in exploring the less stable, more temporary examples of ions.
Web8 apr. 2024 · The delocalization of the positive charge is the main reason. Due to delocalization, the electron deficiency is decreased and the stability is increased. In comparison, the resonance effect is a more dominating factor than substitution. The structures with resonance are better stabilized than others.
Web26 aug. 2024 · Assertion : The lesser the lattice enthalpy more stable is the ionic compound. Reason : The lattice enthalpy is greater, for ions of highest charge and smaller radii. Answer Answer: (d) Assertion is false but reason is true. The greater the lattice enthalpy, more stable is the ionic compound. Q.3. raw head \\u0026 bloody bonesWeb18 feb. 2014 · In the case of electronic configuration of ions, they are more stable than atoms. Explanation Atoms are generally stable. But, if there is a loss in their stability, … raw healers goldWeb19 dec. 2024 · Relative stability of both depends on environment. In gaseous atomic phase N a is somewhat more stable than N a X + and e X − pair due the needed ionization energy. In water, Na is very unstable, as a big amount of energy is released by reaction of e X − with water and by hydration of Na+. That leads to very fast up to explosive reaction. rawhead shootWebIn covalent bonds, two atoms share pairs of electrons, while in ionic bonds, electrons are fully transferred between two atoms so that ions are formed. Let’s consider both types of bonds in detail. Covalent bonds and molecules A covalent bond is formed when two atoms share electron pairs. rawhead supernaturalWeb1. Identify the formulas and charges of the cation and anion. 2. Determine how many of each ion type is needed to make a neutral compound. 3. Place the cation first in the formula, followed by the anion. 4. If more than one unit of a polyatomic ion is needed, place parentheses around the polyatomic ion. 5. rawhead rex t shirtWebBoth ions form because the ion is more stable than the atom due to the octet rule. Forming an Ionic Bond Once the oppositely charged ions form, they are attracted by their positive and negative charges and form an ionic compound. Ionic bonds are also formed when there is a large electronegativity difference between two atoms. raw healingWeb25 jan. 2024 · These ionic species are more stable than the atom due to the octet rule. Forming an Ionic Bond The chemical bond that is formed between \ (2\) atoms through the transfer of one or more electrons from the electropositive or metallic element to the atom of an electronegative or non-metallic element is called an ionic or electrovalent bond. raw healing mastery
