The basic points in Lewis and Langmuir 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.

Answers

In chemistry:
When something is oxidized, it loses electrons.
When something is reduced, it gains electrons.
So the correct statements would be the second to last and third to last statements

The correct statements are -

An element has been oxidized when it has reacted with oxygen gas to produce a compound with the oxygen atom included in its formula,
A compound has been reduced when it originally had an oxygen atom in its formula and lost it as a consequence of reacting with some other element or compound,
An element has been oxidized when, as a consequence of a chemical reaction, it has lost electrons to produce the same element as a product with a more positive oxidation state and
An element has been reduced when, as a consequence of chemical reaction, it has gained electrons to produce the same element as a product with a more negative oxidation state.

Oxidation state, also known as oxidation number, is a measure of the degree of oxidation or reduction of an atom within a compound or ion. It indicates the number of electrons that an atom has gained or lost, or the hypothetical charge that it would have if all the shared electrons in a compound were assigned to the more electronegative atom.

The oxidation state of an atom can be positive, negative, or zero. In a neutral molecule, the sum of the oxidation states of all the atoms must be zero. In ions or compounds, the sum of the oxidation states of all the atoms must be equal to the overall charge of the species.

Oxidation states are assigned based on a set of rules that consider the electronegativity of atoms, the number of valence electrons, and the distribution of electrons in a molecule or ion. The oxidation state provides information about the reactivity, bonding, and redox reactions of substances. It is often represented by Roman numerals or as a signed integer.

What is the atomic mass of one mole of O?

Answers

Oxygen's atomic weight is 16.00 amu. 1 mole of oxygen is 6.02 x 10^23 atoms of oxygen 1 amu = 1.661 x 10^-24g. I hope this helps you. The correct answer for this question is "1.661 x 10^-24g".

Suppose you have designed a new thermometer called the x thermometer. On the x scale the boiling point of water is 129 ?x and the freezing point of water is 13 ?x. Part a at what temperature are the readings on the fahrenheit and x thermometers the same?

Answers

(x1,y1) (x2,y2)

(32,15) (212,135)

y = mx + b

m=(y2-y1)/(x2-x1)

m=.66667

y = .66667*(x) + b

Plug in #s to test for b value

15 = .66667*(32) + b

b = -6.334

y = mx + b

y = .6667*(x) + (-6.334)

F = .6667*(F) + (-6.334)

F = (.6667*(F) = -6.334

(F - .6667F) = -6.334

F(1 - .6667) = -6.334

F = -19

ThermX = F @ -19 degrees

as a result of the gold foil experiment it was concluded that an atom (1) contains protons, neutrons, and electrons(2)contains a small, dense nucleus(3)has positrons and orbitals (4)is a hard and invisible sphere

Answers

It showed that the atom contains a small dense nucleus. The reason why this can be concluded is that the experiment showed that alpha particles can for the most part pass right through the foil. This showed that the nucleus of the atom is very small and takes up a very small portion of the size of an atom since the nucleus is what would reflect the alpha particle. If atoms were not mostly empty space, the alpha particles would have been bounced back and the opposite of what was observed would have happened (all or at least the majority would be bounced back instead the majority getting through with only a small portion being reflected back).

I hope this helps. Let me know in the comments if anything is unclear.

Final answer:

The gold foil experiment, conducted by Ernest Rutherford, discovered the existence of a small, dense nucleus within an atom, making answer (2) the correct one.

Explanation:

The gold foil experiment was conducted by Ernest Rutherford and led to the discovery of a small, dense nucleus within the atom. This means that the correct answer to your question is (2) contains a small, dense nucleus. Prior to this experiment, the widely accepted model was the 'plum pudding' model, which had negatively charged electrons embedded within a positively charged sphere. The gold foil experiment upended this model as it was discovered that most alpha particles passed through the gold foil undeterred, but a small fraction was deflected at large angles, suggesting that a tiny but dense packet of positive charge — identified as the nucleus — existed in the center of the atom. This discovery led to the formation of the Rutherford atomic model.

What value was there in predicting the properties for gaps in Mendeleev's table?

Answers

Predicting the properties for gaps in Mendeleev’s table helps discover new elements. Because during his presentation of his proposed periodic table, he noted some gaps in his table and predicted that there are still unknown elements between those gaps. He uses some prefixes like dvi-, tri-, and eka- in order to give provisional names to his predicted elements. In his periodic table, he also laid out his elements from the lightest to the heaviest element. The lightest elements started from zero, some examples are gases.

Answer:

The Table helps discover new elements.
