Protons: 11 - Neutrons: 12 - Electrons: 11. By analyzing the atomic number, mass number, and net charge, we can determine the number of protons, neutrons, and electrons in the sodium-23 atom.
The sodium-23 atom (Na-23) has a net charge of +1, which means it has one more proton than electrons. To determine the number of protons, neutrons, and electrons in the atom, we need to look at its atomic number and mass number.
The atomic number of an element represents the number of protons in its nucleus. Since the net charge of the sodium-23 atom is +1, it means there is one more proton than electrons. Therefore, the number of protons in the sodium-23 atom is 11.
The mass number of an atom is the sum of its protons and neutrons. To find the number of neutrons, we subtract the number of protons (atomic number) from the mass number. In this case, the sodium-23 atom has a mass number of 23, and since it has 11 protons, we can calculate the number of neutrons:
Mass number - Atomic number = Number of neutrons
23 - 11 = 12 neutrons
Lastly, to find the number of electrons, we need to consider the net charge. Since the sodium-23 atom has a net charge of +1, it means it is missing one electron to become neutral. Therefore, the number of electrons in the sodium-23 atom is 11.
In summary:
- Protons: 11
- Neutrons: 12
- Electrons: 11
By analyzing the atomic number, mass number, and net charge, we can determine the number of protons, neutrons, and electrons in the sodium-23 atom.

Answer:
the last one is the answer
Answer: This is an incomplete combustion reaction.
Explanation:
Combustion reaction is defined as the reaction in which a hydrocarbon produces carbon dioxide gas and water molecule when reacted with oxygen gas. General equation for this reaction is:
Incomplete combustion is also a reaction between oxygen and hydrocarbon in which the products obtained are carbon monoxide, water and carbon. This type of combustion happens when there is insufficient supply of oxygen gas. General equation for this reaction is:
Hence, the hydrocarbon is undergoing an incomplete combustion reaction.
(2) alpha particle, gamma ray, beta particle
(3) gamma ray, alpha particle, beta particle
(4) gamma ray, beta particle, alpha particle
Answer: The order of penetrating power from greatest to least is gamma ray, beta particle, alpha particle.
Explanation:
Penetration power is defined as the movement of particles or the ray through an object. It is directly proportional to the energy of the particle.
So, more is the energy of a particle, more will be its penetrating power.
We know that:
Gamma rays have the highest energy, followed by beta particle and then by alpha particle.
Thus, the ascending order of the penetration power of alpha rays, beta rays, and gamma rays will be:
Alpha rays < Beta rays < Gamma rays
Hence, the order of penetrating power from greatest to least is gamma ray, beta particle, alpha particle.
Answer : The diatomic gas is nitrogen gas, N₂.
Explanation :
First we have to calculate the moles of gas.
Using ideal gas equation:
where,
P = Pressure of gas = 1.00 atm
V = Volume of gas = 4.4 L
n = number of moles of gas = ?
R = Gas constant =
T = Temperature of gas =
Putting values in above equation, we get:
Now we have to calculate the molar mass of gas.
As we are given that the gas is diatomic X₂.
As, 2 atoms of gas X has mass = 28.07 g/mol
So, 1 atom of gas will have mass =
From this we conclude that the nitrogen atom has mass of 14.04 g/mol.
Thus, the diatomic gas is nitrogen gas, N₂.
