Respuesta :
B the atomic number is 20 and then you subtract atomic mass to find the neutrons
There are 20 protons, 21 neutrons,20 electrons are in a neutral atom with the symbol 41Ca.
Explanation:
Given:
The neutral atom with symbol 41Ca
To find:
The numbers of protons, neutrons, and electrons.
Solution:
The given symbol of an atom is Ca which means that the given atom is of calcium.
The atomic number of calcium = 20
The atomic number of atom = Number of protons in an atom
The number of proton in a given calcium atom = 20
The given atom is neutral which means that an equal number of protons and electrons will be present.
The number of electrons = Number of protons = 20
The number of electrons in a given calcium atom = 20
The mass number of an atom is a sum of the number of neutrons and the number of protons
The number of neutrons = n
In the given symbol of calcium atom, the mass number of calcium is also given which is 41.
The mass number of the calcium atom = 41
[tex]41=n+20\\n=41-20=21[/tex]
The number of neutrons = 21
The number of neutrons in a given calcium atom = 21
There are 20 protons, 21 neutrons,20 electrons are in a neutral atom with the symbol 41Ca.
