What term means having the same number of electrons?
Two atoms and/or ions that have the same numbers of electrons are called "isoelectronic". Thus, a lithium cation is isoelectronic with a helium atom, because each has a total of two electrons.
What is an ionic compound with a polyatomic cation and anion and the atoms from the anion are all from the same group?
An example of an ionic compound with a polyatomic cation and anion, where the atoms in the anion are all from the same group, is ammonium phosphate (NH4)3PO4. Here, the cation is the ammonium ion (NH4+), a polyatomic cation, and the anion is the phosphate ion (PO4^3−), which contains phosphorus and oxygen, both belonging to Group 15 and Group 16 of the periodic table, respectively. However, the phosphate itself does not have all its atoms from the same group; for a strict interpretation, consider a compound like ammonium sulfate ((NH4)2SO4), where the sulfate ion (SO4^2−) has sulfur from Group 16 and oxygen from Group 16 as well.
Is molar mass differ in isoelectronic compound?
Yes, the molar mass is different for isoelectronic molecules.
Is the Atomic weight for an element the same when it is in an anion or cation?
The weights of atoms are based primarily on the number of protons and neutrons in an atom. This is because protons and neutrons are many times the weight of electrons. Since electrons contribute a minuscule amount, even on the atomic level, to the mass of the atom, the mass of the atom is taken to be the same whether it is a anion of a cation. Remember, it is the number of electrons in an atom that determines whether it is an anion, cation, or a neutral atom. If there is a different number of neutrons it is called an isotope, and will have a different mass. If it has a different number of protons, it is a different atom and will have a different mass.
Which noble gas is isoelectronic with a calcium ion?
(Ar) Argon because Ca ion is Ca2+ so it give away 2 electrons
What is the symbol for a cation and anion that are isoelectronic with krypton?
Atoms are isoelectronic when they have the same electron configuration. Therefore, an anion isoelectronic to krypton is bromide. A cation isoelectronic to krypton is rubidium.
What is isoelectronic with xenon?
Krypton, radon, and xenon cation are all isoelectronic with xenon because they have the same number of electrons.
What ion is isoelectronic with Xe?
The ion that is isoelectronic with Xe is Kr+. Both Xe and Kr+ have the same number of electrons, with 54 electrons each.
What is isoelectronic with potassium?
Argon is isoelectronic with potassium, as both elements have the same number of electrons - 18 in total. However, the distribution of electrons in the electron shells differs between the two elements.
What term means having the same number of electrons?
Two atoms and/or ions that have the same numbers of electrons are called "isoelectronic". Thus, a lithium cation is isoelectronic with a helium atom, because each has a total of two electrons.
An ionic compound with a polyatomic cation and polyatomic anion The atoms in the anion are all from the same group?
An example of this type of compound is ammonium sulfate (NH4)2SO4, where the polyatomic cation is ammonium (NH4+) and the polyatomic anion is sulfate (SO4^2-). In this case, the atoms in the sulfate anion are all from the same group in the periodic table (Group 16 or the oxygen family).
How does a cation differ from an anion?
A cation is a positively charged ion formed by losing electrons, while an anion is a negatively charged ion formed by gaining electrons. Cations are attracted to cathodes, while anions are attracted to anodes in electrolysis.
Isoelectronic with another element what does this mean?
Two elements are isoelectronic if they have the same number of electrons. This means they will have similar chemical properties and can form similar types of bonds. An example is neon (Ne) being isoelectronic with sodium (Na+).
How do you name binary ionic compound?
Rule 1. The cation is written first in the name; the anion is written second in the name.Rule 2. The name of the cation is the same as the (neutral) element from which it is derived (e.g., Na+ = "sodium").Rule 3. The anion is named by adding the suffix -ide to the root of the element name (e.g., I- = "iodide").
What is isoelectronic with Fluoride?
Hydroxide and water are isoelectronic with fluoride as they have the same number of electrons.
Is molar mass differ in isoelectronic compound?
Yes, the molar mass is different for isoelectronic molecules.
