The octet rule and formal charges must be met in order to achieve the "optimal" electron configuration. Lewis structures use the chemical symbol for each atom to show where it is located within the molecule's structure. Atoms that are joined together are separated by lines (pairs of dots can be used instead of lines). The extra electrons that form lone pairs are shown next to the atoms as pairs of dots. Hydrogen (H) can only form bonds that share two electrons, whereas main group elements of the second period and beyond often react by acquiring, losing, or sharing electrons until they have reached a valence shell electron configuration with a full octet of (8) electrons.

E_photon = energy of the photon
E_i = energy of initial level
E_f = energy of final level
Then we take a look at our Energy Level Diagram for hydrogen. Look at the energy required for n = 7 and then n = 4.
E_photon = E_i - E_f
E_photon = (0.00 eV) - (-0.57 eV)
E_photon = 0.57 eV
Photon energy is the energy carried by a single photon. The amount of energy is directly proportional to the photon's electromagnetic frequency and thus inversely proportional to its wavelength. The higher the frequency of a photon, the higher its energy. The longer the wavelength of a photon, the lower its energy.
Photon energy can be expressed in arbitrary energy units. Commonly used units for expressing photon energy include the electronvolt (eV) and joules (and their multiples such as microjoules). One joule is equal to 6.24 × 1018 eV, so larger units may be more useful to express the energy of higher frequency, higher energy photons, such as photons. B.

calculate the distance of closest approach for a head-on collision between a 5.30 mev alpha particle and the nucleus of a copper atom.
To calculate the distance of closest approach for a head-on collision between an alpha particle and the nucleus of a copper atom, we can use the formula:
r = Z1Z2e^2 / (2m1v^2)
where r is the distance of closest approach, Z1 and Z2 are the atomic numbers of the alpha particle and the copper nucleus, respectively, e is the charge of the electron (1.6 x 10^-19 C), m1 is the mass of the alpha particle, and v is the velocity of the alpha particle.
The atomic number of an alpha particle is 2, since it consists of two protons and two neutrons. The atomic number of copper is 29. The mass of an alpha particle is 6.644 x 10^-27 kg, and its velocity can be calculated from its kinetic energy using the formula:
v = sqrt(2*KE/m1)
where KE is the kinetic energy of the alpha particle in joules. The kinetic energy of a 5.30 MeV alpha particle is 5.30 x 10^6 eV, or 8.478 x 10^-13 J.
Substituting these values into the formula for the distance of closest approach, we get:
r = 229(1.6 x 10^-19 C)^2 / (2*(6.644 x 10^-27 kg)(sqrt(28.478 x 10^-13 J/6.644 x 10^-27 kg))^2
= 5.936 x 10^-15 m
Therefore, the distance of closest approach for a head-on collision between a 5.30 MeV alpha particle and the nucleus of a copper atom is approximately 5.936 x 10^-15 meters.

Which substance has the strongest attractive forces between its particles? salt sugar or wax, then explain, give evidence, and reasoning for fun.
In general, substances with strong attractive forces between their particles tend to have high melting and boiling points and are solids at room temperature.
Salt (sodium chloride) is a solid at room temperature and has a relatively high melting point of 801°C. This is due to the strong attractive forces between its ions (positively charged sodium ions and negatively charged chloride ions).
Sugar (sucrose) is also a solid at room temperature but has a much lower melting point of 186°C. This is because the attractive forces between the sugar molecules are not as strong as the forces between the ions in salt.
Wax is a soft solid at room temperature and has a relatively low melting point. The attractive forces between wax molecules are weaker than those in salt or sugar.
So, in terms of the strength of attractive forces between its particles, salt would be the strongest, followed by sugar and then wax.

What sort of molecule would constitute a covalent bond?Covalent bonds are formed when atoms share electrons to bind together. The majority of the time, nonmetals form covalent connections. For instance, in water (H2O), the hydrogen (H) and oxygen (O) atoms each share an electron pair to form a molecule that consists of two hydrogen atoms single-bonded to one oxygen atom.

classify each reactant as the reducing agent, oxidizing agent, or neither. 5no2− 6h 2mno4− → 5no3− 2mn2 3h2o
While H⁺ is neither an oxidizing nor a reducing agent, and MnO₄⁻ is an oxidizing agent, NO₂⁻ is becoming oxidized, making it the reducing agent.
As to why a reactant?Reactant is a word that is used to represent a balanced chemical. A chemical element that is a reactant is one which is present at the beginning of such a chemical reaction and changes as the reaction develops. They can also be alluded to as reagents or beginning ingredients.
Briefing:5NO₂⁻ + 6H⁺ + 2MnO₄⁻ -----> 5NO₃⁻ + 2Mn²⁺ + 3H₂O
In this reaction let's see what all changes are happening in each species oxidation state.
NO₂⁻ : oxidation state of N is (+4-1=) +3. And
NO₃⁻ : oxidation state of N is (+6-1=) +5. Thus NO₂⁻ is getting oxidized and so it is the reducing agent.
H⁺ : no change in oxidation state of H⁺ hence it is neither oxidizing not reducing agent.
MnO₄⁻ : oxidation state of Mn is (+8-1=) +7.
Mn²⁺ : oxidation state of Mn is +2. Thus oxidation state of Mn is changing from +7 to +2 and hence it is getting reduced. So we can say that MnO₄⁻ is an oxidizing agent.
