An ionic bond forms when atoms blank electrons
8_murik_8 [283]

Answer:

An ionic bond forms when atoms transfer electrons.

Explanation:

Ionic bonds are formed when atoms transfer electrons. (In contrast, covalent bonds are formed when atoms share electrons.)

There's a distinction between the two: when two atoms react to form an ionic bond, one atom would completely lose one electron, while the other would completely gain that electron. The atom that loses the electron becomes a positively-charged ion called a cation, whereas the atom that gains the electron becomes a negatively-charged ion called an anion.

For example, consider the reaction between a sodium \rm Na atom and a chlorine \rm Cl atom: \rm Na + Cl \to NaCl.

When the sodium atom and the chlorine atom encounter, the sodium atom would lose one electron to form a positively-charged sodium ion, \rm Na^{+}. The chlorine atom would gain that electron to form a negatively-charged chlorine ion \rm Cl^{-}.

These two ions will readily attract each other because of the opposite electrostatic charges on them. This electrostatic attraction (between two ions of opposite charges) is an ionic bond.

Overall, it would appear as if the sodium \rm Na atom transferred an electron to the chlorine \rm Cl atom to form an ionic bond.

In contrast, when two atoms react to form a covalent bond, they share electrons without giving any away completely. Therefore, it is possible to break certain covalent bonds apart (using a beam of laser, for example) and obtain neutral atoms.

On the other hand, when an ionic bond was broken, the result would be two charged ions- not necessarily two neutral atoms. The electron transfer could not be reversed by simply breaking the bond.

For example, when table salt \rm NaCl is melted (at a very high temperature,) the ionic bond between the sodium ions and chloride ions would (mostly) be broken. However, doing so would only generate a mixture of \rm Na^{+} and \rm Cl^{-} ions- not sodium and chlorine atoms.

When an electr ic cur rent is passed through water , two colou r less gases are produced. When hydrogen gas makes a po pping sou
kumpel [21]

The lysis reaction with the formation of two different gases, and the synthesis reaction with the reaction of hydrogen and oxygen support that water is a compound and not an element.

<h3>What is electrolysis?</h3>

The electrolysis is the analytical process for the separation or the deposition of the element in the presence of the electric field.

The passing of electric current through water results in the release of two types of gases. Thus, it can be said that water lysis or breakdown forms the release of two elements hydrogen and oxygen supporting the fact that water is a compound and not an element.

The production of water is found to be formed with the reaction of hydrogen with oxygen. Thus it supports that water is a compound and, not an element.

Lithium metal reacts with nitrogen gas to form lithium nitride. identify the balanced reaction that describes this process
Arlecino [84]

Lithium metal reacts with nitrogen gas to form lithium nitride the balanced chemical equation will be 6Li + N₂ → 2Li₃N.

<h3>What is a balanced chemical reaction?</h3>

In a balanced chemical reaction, the number of moles that are present at the side of the reactant must be always equal to the side of product formation this is known as a balanced chemical equation.

The balanced chemical reaction will be 6Li + N₂ → 2Li₃N.

Here 6 moles of lithium is reacting with one nitrogen but as it is in gaseous state it is N₂ after reacting with lithium it will give two moles

Therefore, balanced equation will be 6Li + N₂ → 2Li₃N
