Why do elements want to resemble noble gases?

Simply put: Nobel gases have completely full shells, so they are stable and do not interact much with other elements. That is why other elements ‘mimic’ nobel gases. They want to obtain the stable configuration.

Why do elements gain and lose electrons?

Explanation: Atoms and chemical species lose or gain electrons when they react in order to gain stability. Thus, typically, metals (with nearly empty outer shells) lose electrons to non-metals, thereby forming positive ions. The number of electrons depends on their position on the Periodic table (in simple terms).

Why do atoms of elements gain lose or share valence electrons Why do noble gasses not do this?

The noble gases rarely form compounds. They have the most stable configuration (full octet, no charge), so they have no reason to react and change their configuration. All other elements attempt to gain, lose, or share electrons to achieve a noble gas configuration.

Why do noble gases not lose electrons?

The atoms of noble gases already have complete outer shells, so they have no tendency to lose, gain, or share electrons. This is why the noble gases are inert and do not take part in chemical reactions.

How do atoms gain or lose electrons in order to attain a valence orbital arrangement like that of a noble gas explain?

Three hydroxide ions are needed to form a neutral ionic compound with an aluminum ion. The -ide ending in nitrogen dioxide tells you that this is an ionic compound. The subscript “2” in Mg(OH)2tells you that the charge of the hydroxide ion is (-2). How many atoms of oxygen are in a molecule of Al2(CO3)3?

When atoms gain or lose electrons they become?

An atom that loses one or more valence electrons to become a positively charged ion is known as a cation, while an atom that gains electrons and becomes negatively charged is known as an anion.

Why do atoms gain and lose electrons to have eight electrons in the valence shell?

When atoms have fewer than eight electrons, they tend to react and form more stable compounds. Atoms may lose, gain or share their valence electrons to achieve eight electronic configuration. Thus an atom will continue to form bond until it achieves eight electrons in the outermost shell.

Why do noble gases not bond with other elements?

The noble gases have full outer shells of electrons, and so cannot share other atoms’ electrons to form bonds.

Do atoms gain or lose electrons in chemical reactions in order to increase their energy state?

Atoms gain or lose electrons in chemical reactions in order to increase their energy state. Atoms gain or lose electrons in order to attain a valence orbital arrangement like that of a noble gas. Ionic bonds occur between atoms from adjacent chemical families in the periodic table.

Why do atoms gain or lose electrons?

Atoms gain or lose electrons to attain a stable state on their electron shell. When they do this they form ionic compounds with charges. Q: Why do atoms gain or lose electrons?

Why do noble gases not take part in chemical reactions?

When elements react, their atoms complete their outer shells by losing, gaining, or sharing electrons. The atoms of noble gases already have complete outer shells, so they have no tendency to lose, gain, or share electrons. This is why the noble gases are inert and do not take part in chemical reactions.

Why do cations and anions react to gain or lose electrons?

So atoms or elements, when they exist as ions, they want to lose/gain or share electrons to attain a stable electronic configuration and achieve an octet/duplet valence shell structure resembling that of noble gases. Hence cations react to lose electrons, anions react to gain electrons.

Why do some atoms have a negative charge on electrons?

Some atoms have nearly eight electrons in their valence shell and can gain additional valence electrons until they have an octet. When these atoms gain electrons, they acquire a negative charge because they now possess more electrons than protons.
