Sorry, I cannot display tables. However, I can provide you with the information.
The number of subatomic particles in a krypton atom are as follows:
Inside the nucleus:
- Protons: The atomic number of krypton is 36, so it contains 36 protons.
- Neutrons: The mass number of krypton is 84, and the atomic number is 36. Therefore, the number of neutrons can be calculated by subtracting the atomic number from the mass number. 84 - 36 = 48 neutrons.
Outside the nucleus:
- Electrons: Since atoms are electrically neutral, the number of electrons is equal to the number of protons. Therefore, krypton also has 36 electrons surrounding the nucleus.
To determine the number of subatomic particles inside and outside the nucleus of a krypton atom, we need to understand the basic structure of an atom.
An atom consists of a central nucleus, which contains protons and neutrons, and electrons that orbit around the nucleus.
Given that the atomic number of krypton is 36, this tells us that there are 36 protons in the nucleus of a krypton atom.
The mass number of a krypton atom is 84. The mass number is the sum of the number of protons and the number of neutrons in the nucleus. Therefore, the number of neutrons in a krypton atom can be calculated by subtracting the atomic number (number of protons) from the mass number:
Number of neutrons = Mass number - Atomic number
Number of neutrons = 84 - 36 = 48
So, the number of subatomic particles inside the nucleus of a krypton atom is:
36 protons
48 neutrons
The electrons are found outside the nucleus. The number of electrons in a neutral atom is equal to the number of protons. Since krypton has 36 protons, there are also 36 electrons outside the nucleus.
In summary, the number of subatomic particles inside and outside the nucleus of a krypton atom is as follows:
Inside the nucleus:
36 protons
48 neutrons
Outside the nucleus:
36 electrons
Therefore, the correct table showing the number of subatomic particles inside and outside the nucleus of a krypton atom would be:
Nucleus:
Protons: 36
Neutrons: 48
Outside the nucleus:
Electrons: 36
To determine the number of subatomic particles inside and outside the nucleus of a krypton atom with an atomic number of 36 and a mass number of 84, you will need to understand the concept of atomic structure.
The atomic number of an element represents the number of protons in its nucleus. In this case, krypton has an atomic number of 36, meaning it has 36 protons.
The mass number of an atom is the sum of the number of protons and neutrons in its nucleus. To find the number of neutrons, subtract the atomic number from the mass number. In this case, 84 - 36 = 48 neutrons.
So, the krypton atom has 36 protons and 48 neutrons in its nucleus.
To find the number of subatomic particles outside the nucleus (i.e., the electrons), you need to know the electron configuration of krypton. The electron configuration of krypton is 2-8-18-8, which represents the distribution of electrons in its energy levels.
In the first energy level, there are 2 electrons.
In the second energy level, there are 8 electrons.
In the third energy level, there are 18 electrons.
In the fourth energy level, there are 8 electrons.
Adding these up, you get a total of 36 electrons.
Therefore, the number of subatomic particles inside the nucleus of the krypton atom is 36 protons and 48 neutrons, while the number of subatomic particles outside the nucleus is 36 electrons.
Unfortunately, I am unable to display tables, so I cannot directly show you a table with the information.
