Why are ions usually formed during the interaction of metal with nonmetal and not between two metals?

Chemistry

Alik [6]3 years ago

Explanation:

Ions are always formed when metals and non-metals interact because metals are electropositive. They willing release electrons to non-metals that are electronegative.

This activity results in charge separation. The transfer of electrons from one specie to another is what results in an ionic bond and the precedence of charged particles.

Between non-metals, the electrons are jointly shared. Therefore, there is no charge separation.

Describe the pattern of the lewis dot structure of the first 18 elements

posledela

Explanation: Lewis dot structures are the structures which represent the valence electrons of an atom. The dots in the structure are considered as the valence electrons.

First 18 elements of the periodic table are Hydrogen(H), Helium (He), Lithium (Li), Beryllium (Be), Boron (B), Carbon (C), Nitrogen (N), Oxygen (O), Fluorine (F), Neon(Ne), Sodium (Na), Magnesium (Mg), Aluminium (Al), Silicon (Si), Phosphorous (P), Sulfur (S), Chlorine (Cl) and Argon(Ar).

The valence electrons are the electrons which are present in the outermost shell of an atom. The electronic configuration of the elements are:

Hydrogen (H) = $1s^1$ ; Valence electrons = 1

Helium (He) = $1s^2$ ; Valence electrons = 2

Lithium (Li) = $1s^22s^1$ ; Valence electrons = 1

Beryllium (Be) = $1s^22s^2$ ; Valence electrons = 2

Boron (B) = $1s^22s^22p^1$ ; Valence electrons = 3

Carbon (C) = $1s^22s^22p^2$ ; Valence electrons = 4

Nitrogen (N) = $1s^22s^22p^3$ ; Valence electrons = 5

Oxygen (O) = $1s^22s^22p^4$ ; Valence electrons = 6

Fluorine (F) = $1s^22s^22p^5$ ; Valence electrons = 7

Neon (Ne) = $1s^22s^22p^6$ ; Valence electrons = 8

Sodium (Na) = $1s^22s^22p^63s^1$ ; Valence electrons = 1

Magnesium (Mg) = $1s^22s^22p^63s^2$ ; Valence electrons = 2

Aluminium (Al) = $1s^22s^22p^63s^23p^1$ ; Valence electrons = 3

Silicon (Si) = $1s^22s^22p^63s^23p^2$ ; Valence electrons = 4

Phosphorous (P) = $1s^22s^22p^63s^23p^3$ ; Valence electrons = 5

Sulfur (S) = $1s^22s^22p^63s^23p^4$ ; Valence electrons = 6

Chlorine(Cl) = $1s^22s^22p^63s^23p^5$ ; Valence electrons = 7

Argon (Ar) = $1s^22s^22p^63s^23p^6$ ; Valence electrons = 8

Elements hydrogen and helium belong to period 1 of the period table, so the lewis dot structures will have maximum of 2 electrons

Elements from lithium to neon belong to period 2 and the lewis dot structures will have maximum of 8 electrons.

Elements from sodium and argon belong to the period 3 of the periodic table, and will have maximum of 8 electrons in their lewis dot structures.

Lewis dot structures are attached below.

stiv31 [10]

<span>There are five main branches of chemistry including, physical, analytical, biochemistry, organic and inorganic chemistry. I would have to say that the answer to this question is none of the above. The answers given to this multiple choice question are some of the branches of biology. If the question asked for the branches of biology then the answer would be all of the above.</span>

An acid has an acid dissociation constant of 2.8x10^-9. What is the base dissociation constant of its conjugate base?

jok3333 [9.3K]

PH=-lg[H⁺]
pH=-lg(2.8×10⁻⁹)=8.553

pOH=14-pH
pOH=14-8.553=5.447

[OH⁻]=10^(-pOH)
[OH⁻]=10⁻⁵·⁴⁴⁷=3.6×10⁻⁶
