Highlights the basic points in lewis and lannngmuir theory of electrovalency

Answers

Answer 1

Answer: The correct answer for the question that is being presented above is this one: "Electrovalency is characterized with the transferring of one or more electrons from one atom to another together with the formation of ions and as well as the number of positive and negative charges.

The Lewis and Langmuir theory of electrovalency (and as well as Kossel's) is dealing with Ionic bonds.

Lewis: electron-pair sharing, octet rule, Lewis Symbols or StructureLangmuir: introduced term "covalent" bond, and popularized Lewis's ideas

The Lewis-Langmuir electron-pair or covalent bond is referred as the homopolar bond, where the complete transfer of electrons give rise to ionic, or electrovalent bond (1) through attraction of opposite charges.

Given the reaction:Mg(s) + 2 AgNO3(aq)--> Mg(NO3)2(aq) + 2 Ag(s)
Which type of reaction is represented?
(1) single replacement (3) synthesis
(2) double replacement (4) decomposition

Answers

Answer: (1) single replacement

Explanation:

A single replacement reaction is one in which a more reactive element displaces a less reactive element from its salt solution.Thus magnesium can easily lose electrons as compared to silver and result in the formation of magnesium nitrate and silver.

$Mg(s)+2AgNO_3(aq)\rightarrow Mg(NO_3)_2(aq)+2Ag(s)$

Double displacement is a chemical reaction in which ion exchange takes place.

Synthesis reaction is a chemical reaction in which two reactants combine to give a single product.

Decomposition is a chemical reaction in which one substance decompose to give two or more than two products.

reaction: Mg(s) + 2 AgNO3(aq) → Mg(NO3)2(aq) + 2 Ag(s)
Which type of reaction is represented?

double replacement

double replacement a bimolecular process involving the exchange of bonds between the two reacting chemical species, which
results in the creation of products with
similar or identical bonding affiliations.
To illustrate, consider two chemical species, AB and CD, which react to give AD and CB:

AB + CD → AD + CB

The mass of a proton is equal to the mass of?

Answers

It is about equal to the mass of the neutron. So, most people just say that they have the same mass.

*Hope that helps and enjoy Brainly :)*

The answer would be neutron. Well, they do not have the exact same mass, only a difference of about 0.98 or even less than that. So they are counted as equals.

To show the electron configuration for an atom, what is the advantage of using an orbital notation compared to a dot structure? Orbital notation takes up less space. Orbital notation shows the spin of the electrons. Orbital notation makes it easier to count the electrons. Orbital notation shows the electron distribution in shells.

Answers

Correct answer: Option B i.e. Orbital notation shows the spin of the electrons.

Reason:
Dot diagram provides only the electrons that are present in valance shell. Furthermore, it provides no information about the electron spin. On other hand, orbital notation is writing taking into consideration aufbau principle, Hund's rule and Pauli's exclusion principle. Hence, it provides correct description of electron distribution of electrons in atoms. Furthermore, orbital notation shows the spin of the electrons.

Answer: The correct answer is Orbital notation shows the spin of the electrons.

Explanation:

Advantages of Orbital notation :

One can easily count total numbers of electron in an atom
It conveys the distribution of electrons in the shells.
It also tells us about the spin of the electrons.

Where as spin of the electrons is not conveyed by the electron dot structure.

Hence, the corrects answer is : Orbital notation shows the spin of the electrons.

Which of the notations below is another way to write the name of the following nuclide?A.iodine-53

B.iodide-53

C.iodide-127

D.iodine-127

Answers

Answer: D.iodine-127:

Explanation:

1) As per the definition of nuclide, it is the atomic spieces (the atom) characterized by the nucleons (protons and neutros).

2) To notation for a nuclide is the name of the atom followed by a hypen (without blank spaces) and the mass number.

3) The mass number is the sum of protons and neutrons.

4) From that, you can tell this about the four choices given:

A.iodine-53: is not correct because that would mean that the mass number is 53, which cannot be right as the atomic number of iodine is 53 meaning that it has 53 protons, and so that notation is not including the neutrons.

B.iodide-53: is not correct because the name of the atom is iodine, not iodide (also the mass number cannot be for the same reason explained above)

The name iodide is reserved for the ions from iodine not for the atom.

C.iodide-127: incorrect due to the name iodide, for the same reason explained above.

D.iodine-127: this is correct choice. It is the name of the isotope of the iodine with mass number 127, which means that the atom has 53 protons and 74 neutrons (53 is the atomic number and 74 is calculated from 127 - 53)
