Plz Plz HelpWhich Model Shows 5 Electrons In The Outer Shell Of The Atom?A.2B.3C.4D.1

Answers

Answer 1

Answer:

D

Explanation:

there are 5 electrons in the outer shell of the first picture

Answer 2

According to electronic configuration, model 1 shows 5 electrons in the outer shell of the atom.

What is electronic configuration?

Electronic configuration is defined as the distribution of electrons which are present in an atom or molecule in atomic or molecular orbitals.It describes how each electron moves independently in an orbital.

Knowledge of electronic configuration is necessary for understanding the structure of periodic table.It helps in understanding the chemical properties of elements.

Elements undergo chemical reactions in order to achieve stability. Main group elements obey the octet rule in their electronic configuration while the transition elements follow the 18 electron rule. Noble elements have valence shell complete in ground state and hence are said to be stable.

Iodine monochloride (ICl) has a higher boiling point than bromine (Br2) partly because iodine monochloride is a(n)

Answers

Answer: polar molecule.

Explanation:

The boiling point is the temperature at which the vapor pressure of a liquid equals the external pressure surrounding the liquid. The boiling point is dependent on the type of forces present.

Iodine monochloride (ICl) is a polar molecule due to the difference in electronegativities of iodine and chlorine. Thus the molecules are bonded by strong dipole dipole forces. Thus a higher temperature is needed to generate enough vapor pressure.

Bromine [tex](Br_2)[/tex] is a non polar molecule as there is no electronegativity difference between two bromine atoms. The molecules are bonded by weak vanderwaal forces and thus has low boiling point.

A small amount of solid potassium dichromate is added to water and stirred until all of the solid has dissolved and a clear orange liquid is produced. This process may be described as: Group of answer choices the formation of a heterogeneous mixture. dissolution of the molecular compound sublimation. dissolution and dissociation of the ionic compound.

Answers

Answer: dissolution and dissociation of the ionic compound.

Explanation:

Ionic compound is formed by the transfer of electrons.

For formation of a neutral ionic compound, the charges on cation and anion must be balanced. The cation is formed by loss of electrons by metals and anions are formed by gain of electrons by non metals.  

Here potassium metal forms [tex]K^+[/tex] cation and [tex]Cr_2O_7^{2-}[/tex] anion which exchange their oxidation states to form [tex]K_2Cr_2O_7[/tex].

When ionic compound is dissolved in water, it dissociates to its respective ions.The ions form bonds with oppositely charged ions of water molecules and thus get dissolved in water called as dissolution.

what chemical reaction type is Pb + 2 H3PO4 --> 3 H2 + Pb3(PO4)2

Answers

Answer:

single displacement reaction

Explanation:

it is because an atom(Pb) dispalces another atom(H) in H3PI4

The given chemical reaction is single displacement reaction.

What is single displacement reaction?

When one element in a molecule gets replaced by another, is therefore called a single displacement reaction.

The given reaction is Pb + 2 H3PO4 → 3 H2 + Pb3(PO4)2

It can be seen that when lead is treated with H3PO4 then it will give Pb3(PO4)2 and hydrogen reaction. It is a kind of single displacement reaction.

Therefore, the given reaction is single displacement reaction.

(3) 235 U + in ~ 13% Ba + Kr + 3n

(4) Li + H → He + He

a. 1

b. 2

C 3

d. 4

Answers

Answer:

a. 1

Explanation:

Radon is a member of group 18. It is an odorless heavy gas, that emanates from materials that contain uranium.

Rn is a decay product of 226-Ra, a member of the uranium decay series. The spontaneous  decay of Rn decay leads to the emission of an alpha particle.

Rn has a half-life of about 3.8 days and its decay product is 218Po.

The nuclear reaction which shows a spontaneous decay is Rn 21% Po + He.

What is spontaneous reaction?

Those reaction in which value of their enthalpy change and change in Gibb's free energy is negative, are spontaneous in nature.

Among all of the given reaction, only first reaction is spontaneous in nature because the given element Radon (Rn) is the product of the decay of uranium series. And in this reaction energy is emitted in the form of alpha particles.

Hence, option (1) is correct.

How many unpaired electrons are present in V3+?​

Answers

Answer: two unpaired

Explanation: In general, electrons are removed from the valence-shell s-orbitals before they are removed from valence d-orbitals when transition metals are ionized. And thus, V3+ is paramagnetic, because it has two unpaired 3d-electrons.
