The given atom contains 32 neutrons, 28 electrons, and is identified as Nickel (Ni) based on its 28 protons.

An atom's mass number is the sum of its protons and neutrons. Given that this atom has 28 protons and a mass number of 60, we subtract the number of protons from the mass number to find the number of neutrons. Therefore, 60 mass number - 28 protons equals 32 neutrons. As the number of protons in a neutral atom equals the number of electrons, this atom has 28 electrons.

The identity of the atom is determined by the atomic number which is equal to the number of protons. In this case with 28 protons, this atom is Nickel (Ni), according to the periodic table.

Answer:

A.) An isotope is an atom that has the same number of protons (or the same atomic number) as other atoms of the same element do but that has a different number of neutrons (and thus a different atomic mass)

B.) They are alike because every element has its own isotopes, H has three isotopes protium, deuterium, tritium

C.) They are different from each other due to having the same number of protons but a different number of neutrons

Isotopes are variations of a single element with the same proton count but various neutron counts. As a result, their chemical properties are comparable, but they may have different physical characteristics, such as atomic mass and stability.

Explanation:

Isotopes are various versions of a single element that have varied numbers of neutrons but the same number of protons. Isotopes of the same element share the same number of protons and electrons, hence they essentially have the same chemical properties.

However, due to variations in their atomic weights, isotopes of a particular element might have different physical characteristics. Different stability levels are frequently the result of this variation in atomic mass.

Some isotopes may also be radioactive, which means they are unstable and release radiation as they decay over time.

The energy of a photon with a wavelength of 6.4x10^-7 m can be calculated using Planck's equation, E = hc/λ, giving a result of E = 3.11 x 10^-19 Joules.

To calculate the energy of a photon of radiation with a wavelength of 6.4x10^-7 m, you use the equation derived from Planck's equation, specifically E = hc/λ, where E is the energy of the photon, h is Planck’s constant (6.626 × 10^-34 J-s), c is the speed of light (3.00 × 10^8 m/s), and λ is the wavelength. So plugging in the given wavelength, we get:

E = (6.626 × 10^-34 J-s)*(3.00 × 10^8 m/s) / 6.4x10^-7 m

Performing this calculation gives E = 3.11 x 10^-19 Joules. This is the energy of the photon.

Answer:

Zero; Three

Explanation:

The quantum numbers are the set of four described unique values that describes each electron in the orbitals of the atom. The four quantum numbers are the principal, azimuthal, magnetic, and spin.

The principal quantum number (n) gives the energy levels of the electrons. The value of n is always n ≥ 1.

The azimuthal quantum number, also known as the orbital quantum number, describes the shape of the subshell. The values of this quantum number ranges from 0 ≤  ℓ ≤ n − 1.

For n = 1,

The value of:  ℓ = n-1 = 1-1 = 0

∵  ℓ = 0 ⇒ s-orbital

Therefore, in n=1 shell, there is only one value of ℓ. So, there is only one s-orbital and zero p-orbital.

For n > 1,

The value of: l = n-1 > 0

Therefore, for n > 1 shell, there are more than one values of ℓ. So, n > 1 shells contains a set of three p-orbitals each.

Explanation

The interaction of a weak base with water is represented by the equation B(aq) + H₂O(l) ⇒ BH+(aq) + OH⁻(aq), where the weak base forms its conjugate acid and a small proportion of hydroxide ions. An example of this is the reaction of trimethylamine with water, which does not fully dissociate and reaches equilibrium mostly in the nonionized base form.

The equation that represents the interaction of a weak base with water is B(aq) + H₂O(l) ⇒ BH+(aq) + OH⁻(aq). This equation shows that when a weak base (represented by B) reacts with water, it forms its conjugate acid (BH+) and hydroxide ions (OH⁻), though not to the extent that a strong base would. The reaction of water acting as an acid with the weak base forms these two products. A weak base will give only a small proportion of hydroxide ions compared to a strong base, which fully dissociates in water.

For example, a weak base such as trimethylamine ((CH3)3N), interacts with water as follows: (CH3)3N(aq) + H₂O(l) ⇒ (CH3)3NH+(aq) + OH⁻(aq). This reaction reaches an equilibrium where most of the base is in the nonionized form.

Overall, the strength of a base is determined by its tendency to form hydroxide ions when dissolved in water. The equilibrium constant for the ionization of a weak base, known as the base ionization constant (Kb), helps in quantitating this tendency. A base that has a Kb value closer to that of water is a weaker base, whereas one with a Kb value further from that of water is a stronger base.

Answer:

A.Atoms are made of even smaller substances called subatomic particles

Explanation:

Atoms are made up of small subatomic particles such as protons, electrons and neutrons.  

Protons and neutron are located in the center of the atom. Electrons orbit the center of the nucleus. Hence option A is incorrect.

Properties of an atom can be studied. The chemical property of an aton depends on its atomic number or the number of protons. Some atoms are inherently unstable and their radioactive properties are also studied. Hence option B is incorrect.  

Answer:the Density is 0.22 and the Substance is Cork

Explanation:

Ions can be made by single element or covalently bonded group of elements. On removing an electron from an atom, atoms occupy positive charge.

Any species that contain charge whether it is positive charge or negative charge is called ions. The example of polyatomic ions are sulfate, phosphate, nitrate etc.

Cation is the species that loose electron and attain positive charge while anion is a species which gain electron and attains negative charge. Electrons are negatively charged. If we remove negative particles, the leftover atom is positive. when anion and cation combine in fixed ration the the overall charge of the molecule is zero that is molecule is neutral.

Therefore, on removing an electron from an atom, atoms occupy positive charge.

We are given the complete reaction:

3 H2(g)  +  N2(g) → 2 NH3(g)

First let us convert mass to moles.

moles H2 = 5.22 kg / (2 kg/kmol) = 2.61 kmol H2

moles N2 = 31.5 kg / (28 kg/kmol) = 1.125 kmol N2

Then we find for the limiting reactant. The limiting reactant is the one who has lower (moles/coefficient) ratio.

H2 = 2.61 / 3 = 0.87

N2 = 1.125 / 1 = 1.125

Hence the H2 is the limiting reactant so we should base the calculation of NH3 from it. We see that 2 moles of NH3 is produced for every 3 moles of H2, therefore:

moles NH3 = 2.61 kmol H2 * (2 kmol NH3 / 3 kmol H2) = 1.74 kmol

The molar mass of NH3 is 17 kg/kmol, therefore the mass NH3 is:

mass NH3 = 1.74 kmol * 17 kg/kmol

mass NH3 = 29.58 kg
