Answer: valence electrons

Explanation:-

Chemical bond is formed either by sharing of electrons or transfer of valence electrons.

Chemical reactivity is defined as the tendency of an element to loose or gain electrons which are present in the last or valence shell which are called as valence electrons.

A covalent bond is formed when an element shares its valence electron with another element. This bond is formed between two non metals.

$HF$ is formed by sharing of valence electrons of hydrogen and fluorine to complete their octet.

An ionic bond is formed when an element completely transfers its valence electron to another element. The element which donates the electron is known as electropositive element and forms a positively charged ion called as cation. The element which accepts the electrons is known as electronegative element and forms a negatively charged ion called as anion.

Thus valence electrons participate in chemical bonding.

_____ bonds are formed when the electronegativity difference is 0.4 > 2.0. Give two examples:

34kurt

Ionic Bond is formed when the electronegativity difference is 0.4 > 2.0. Electronegativity is a term that can be defined as a tendency of an atom to attract electron towards its own self.

Explanation:

Electronegativity is a term that can be defined as a tendency of an atom to attract electron towards its own self.

An electronegativity of an atom is affected by

The atomic number of the atom
Secondly by the distance at which the valence electron are residing from the nucleus

1. In case the electronegativity difference (which is denoted by ΔEN) is less than 0.5 then the bond formed is known as Nonpolar covalent.

2. In case the ΔEN is in between 0.5 and 1.6, the bond formed is referred to as the Polar covalent

3. In case the ΔEN is more /greater than 2.0, then the bond formed is referred to as Ionic Bond

2 Examples of Ionic bonds

The formation of sodium fluoride, NaF, from a sodium atom and a fluorine atom is an example of Ionic bond formation.
Another example is the formation of NaCl from sodium (Na),which is a metal, and chloride (Cl), which is a nonmetal

Is MgS ionic or covalent

Keith_Richards [23]

Answer:

Ionic

Explanation:

Mg has 2 electron in it's outermost orbit, by donating this two electron to Sulfur it get stable mg 2+ electronic configuration while sulfur has 6 electron in it's outermost shell ,so sulfur accept this 2 electron and complete it's octet and become s2–.

Explain why most metals are malleable and ductile but ionic crystals are not

Dima020 [189]

Throughout the metallic structure allowing the atoms to slide past each other. This sliding is why metals are ductile and malleable. Ioniccompound must break bonds to slide past one another, which causes the ionic material to split and crack.

What is the cost to drive to Los Angeles from San Francisco a distance of 405 miles if the cost of gasoline is $2.90 a gallon an

choli [55]

Answer: $46.98

Explanation:

The distance to drive to Los Angeles from San Francisco is 405 miles. Since the car get 25 miles per gallon of gas, for 405 miles, the car will use:

= 405/25 = 16.2 gallons

Since the cost of gasoline is $2.90 a gallon and the car will use 16.2 gallons. The cost will be:

= $2.90 × 16.2 gallons

= $46.98
