How can electronegativity be used to explain the reaction we see in terms of the numbers and types of bonded being formed in lit

hium?

kolezko [41]3 years ago

Explanation:

Lithium is an electropositive element that readily loses electrons.

Oxygen is electronegative and it will readily accept electrons.

 Due to this significant electronegativity differences between the two species they form electrovalent or ionic bonds between them.

  2atoms of Li lose two electrons:

      Li  →  Li²⁺ + e⁻

             Lithium isoelectronic with helium

 For oxygen;

      O + 2e⁻   →  O²⁻

                          Oxygen is isoelectronic with Neon

Two ions of the lithium combines with the oxygen to form the bond;

                   4Li + O₂  →  2Li₂O

The electrostatic attraction between the two ions forms the ionic bond

Classify the following as a solution, suspension or colloid
frosja888 [35]

Answer:

Solution - (a) Brine . Suspension - (c) sand and water, (g) chalk and water​ Colloid - (e) air,  (f) smoke , (d) soda , (b) milk

Explanation:

A solution is an homogeneous mixture of two or more compounds.

A suspension is a heterogeneous mixture of two or more compounds while a colloid is a homogeneous mixture of two or more compounds with suspended particles which do not settle.

So, under these definitions, the classifications are as follows-

Solution - (a) Brine .

Suspension - (c) sand and water, (g) chalk and water​

Colloid - (e) air,  (f) smoke , (d) soda , (b) milk

Atoms of which two elements have a combined total of 23 protons?
Alik [6]

Answer:

A

Explanation:

Sodium has 11 electrons and Magnesium has 12 electrons. Since here you need to consider atoms, they must have equal amount of protons as electrons to be considered neutral, and so an atom.

So simply 11+12 =23

Which concept describes the formation of four equivalent, single, covalent bonds by carbon in its compounds that resembles metha
Montano1993 [528]
Carbon is special and unique because it is able to form different compounds with a lot of elements, including itself. When it bonds with itself, this is possible because of the concept of hybridization. It is the mixing of atomic orbitals into a new hybrid orbital. In this case, methane is formed through the sp³ hybridization.
