These are the nuclear reactions of the unstable nuclide.
What is nuclear equation?
An equation that specifies the nuclides involved in the reaction, their mass numbers and atomic numbers, as well as the other particles involved in the reaction, is used to describe nuclear reactions.
What is unstable nuclide?
In their valence shell, they have two or eight electrons. They don't acquire, shed, or share electrons.
The ratio of the number of neutrons (N)
to the number of protons (Z)
determines the most likely mode of decay. The atomic number of an atom is represented as the number of protons (Z)
The difference between mass number(A)
and atomic number is represented as the number of neutrons(N). According to the (N/z)
value, the type of decay can be identified.
The nuclear stability belt is drawn between the number of neutrons taking at the y- axis and number of protons at the x- axis. Those lying above or below the belt are unstable nuclides while those lying at the belt are stable nuclides. This belt helps to determine the type of decay that occurs in a species, whether it is alpha decay, beta decay, positron decay or electron capture.
Number of protons (Z)= atomic number
Number of neutrons (N) = mass number(A)- atomic number(z)
If (N/z)
value is greater than 1, then it undergoes β decay. This is because the element has more neutrons and it can tend to convert into a proton by beta decay. The daughter nucleus produced from this decay has increased the atomic number by 1 unit compared to the parent nuclei and there is no change in the mass number.
X= parent nucleus
Y= daughter nucleus
If (N/z)
value is less than 1, then it undergoes positron emission. This is because the element has less neutrons and it cannot tend to convert into a proton. Therefore, it undergoes positron emission in which the daughter nucleus produced from this decay has decreased the atomic number by 1 unit compared to parent nuclei and there is no change in the mass number.
X= parent nucleus
Y= daughter nucleus
If (N/z)
ratio is too low with greater than atomic number of 82, there are too many protons and the nuclide will undergo alpha decay. The alpha decay for any element X is shown below.
A A-4 4

Many organic reactions involve more than a single step. A reactive species that formed in one step and used up in the next is called a reactive _____. Such a reactive species can sometimes be isolated, even though it may be short-lived, unlike the ____ state, which is the unstable energy maximum for each step.
A reactive species that formed in one step and used up in the next is called a reactive intermediate. Such a reactive species can sometimes be isolated, even though it may be short-lived, unlike the transition state.
A certain configuration along the reaction coordinate constitutes the transition state of a chemical reaction. It is described as the condition corresponding to the maximum potential energy along this reaction coordinate. When a molecule is in a transitional state, it is neither a substrate nor a product. The transition state, an unstable structure that exists between the chemical structures of substrates and products, is the first step in every chemical transformation.
A short-lived, highly reactive molecule with high energy is known as a reactive intermediate or an intermediate. It swiftly transforms into a more stable molecule when produced in a chemical process. These chemicals can only be isolated and kept in storage under rare circumstances. Carbocation, carbanion, and the free radical are the three reactive intermediates.

The number of kilowatt-hours of electricity required to produce 4.60kg of metallic sodium from the electrolysis of molten NaCl(s) is_________when the applied emf is 4.50V
The number of kilowatt-hours of electricity required to produce 4.60kg of metallic sodium from the electrolysis of molten NaCl(s) is 3.13 kWh when the applied emf is 4.50V
An equation for the reaction can be given as follows;
[tex]Na^{+} + e^{-} ---- > Na (s)[/tex]
Hence, the moles of Na is equal to the moles of electron used
Therefore, we can calculate the number of moles of sodium as follows;
No of moles = mass ÷ molar mass
No of moles = 4600 g ÷ 23 g/mol (As 1 kg = 1000 g)
No of moles = 200 mol
As Q = n × F; where F represents Faraday's constant
Q = 200 mol × 96500 C
Q = 19,300,000 mol C
The relation between electrical energy and Q is as follows;
E = Q × V
Now we can substitute the given values into the above formula and then calculate the value of electricity as follows;
E = 19,300,000 × 4.50
E = 86,850,000 J
As 1 J = 2.77 × 10^-7 kWh
Therefore;
86,850,000 ÷ 2.77 × 10^-7 kWh = 3.13 kWh
Hence, we can conclude that 3.13 kilowatt-hours of electricity is required to produce 4.60kg of metallic sodium from the electrolysis of molten NaCl(s)

A chemical process in which electrons are moved between two reactants is referred to as a redox reaction. The alteration in the oxidation states of the reacting species can be used to pinpoint this electron transfer.

if a scientist wants to know how many mole of graphene contain 6.71 x 1024 atoms, what is the conversion factor that you will need to use?
The conversion factor that you will need to use is Avogadro's Number.
What is Avogadro's number?
The number of units in a mole of any substance, which is determined by its molecular weight in grams, is equal to 6.02214076 1023. Depending on the composition of the substance and the characteristics of the reaction, the units may be electrons, atoms, ions, or molecules.
What is atom?
An atom is a unit of matter that specifically characterizes a chemical element. One or more negatively charged electrons surround the central nucleus of an atom, which is made up of all of them. One or more protons and neutrons, which are relatively heavy particles, can be found in the positively charged nucleus.
Firstly, we will divide the given number of atoms by Avogadro's number to find the number of moles. After finding moles, we will multiply them with molar mass to find the weight of graphene containing given number of atoms.
Therefore, conversion factor that you will need to use is Avogadro's Number.

From the given lewis structure and what you know about vsepr theory, identify the shape of the molecule.
According to VSEPR theory the shape of the molecule is trigonal bipyramidal.
What is the VSEPR theory?The VSEPR theory postulates that the shape of a molecule can be predicted by the electron pairs that surround the central atoms of the molecule. The valence shell electron pair repulsion (VSEPR) uses 3-D molecular geometry.
The VSEPR is a geometry that minimizes repulsion between electrons. The shape of the molecule is "trigonal bipyramidal" because of the presence of 2 single bonds in the X atom atom attached to the Y atom. The 5 main shapes of VSEPR are linear, trigonal planar, tetrahedral, trigonal bipyramidal and octahedral.
The full question is:
A Lewis structure is a two-dimensional representation of a molecule that does not necessarily show what shape that molecule would take in three dimensions.
