How do you know how many protons an atom has by looking at a picture of it?

The number of protons in an element is the same as its atomic number. Hydrogen (atomic number 1) has 1 proton. Gold (79) has 79 protons, and so on. The number of neutrons is the same as its atomic number.

How do you find the chemical element of an atom?
If you know how many protons the atom has, then that can tell you what element from the periodic table is classifying the atom.
How do you find the number of protons or electrons in a neutral atom of an element?
in a neutral atom the no.of electrons and protons are the same. so what you have to only know is the atomic no.of that element
What is in the center of the atom?
Nucleus. Composed of Protons and neutrons. Can be sub-divided further but you probably don't have to know that. (quarks and muons and such.)
How do you calculate number of electrons required for the reaction?
For each element, the number of protons it has is equal to the number of electrons it has. However, if the atom has a different amount of electrons, then the charge will tell you that. If the charge is negative (-) then that says how many electrons the atom has gained, and if the charge is positive (+) then that says how many electrons the atom has lost.
How many protons electrons and neutrons does an atom with an atomic number of 50 and mass number of 125?
If its a neutral atom, there will be the same number of protons as electrons. The atomic number will tell you how many protons there are, so there are 50 protons and 50 electrons.The mass number is the sum of the number of protons (or electrons in a neutral atom) and the number of neutrons. Since we know there are 50 protons, we subtract 125 with 50 to get 75 neutrons.
If you know the number of electrons in a neutral atom can you determine what the element is?
Yes, in a neutral atom the number of electrons and protons is equal, and it is the number of protons that determines what element the atom is. So, by looking at the number of electrons you can tell what element it is.
How do we know what makes up the atom?
An atom contain protons, neutrons and electrons.
The is determined by the number of protons in an atom?
The number of protons in the nucleus of an atom is known as the atomic number, which determines the chemical element, essentially different numbers of protons mean change the element you are looking at and hence the properties and reactions of that element.
How do we know what parts make up the atom?
An atom contain protons, neutrons and electrons.
What do you need to know to find the numbers of protons in an atom?
the protons are the same number of electrons in a neutral atom and they aren't changeable but different signal
How do you find the number of electrons in an atom if you know the number of protons and neutrons?
In a neutral atom, the number of electrons is equal to the number of protons of the nucleus.
If you know how many electrons an atom has what else do you know about this atom?
Generally how many protons it has, therefore what type of atom it is (i.e. carbon, hydrogen etc.)
How many protons are in a neurtal nitrogen atom?
There are seven protons within the nucleus of a Nitrogen atom. Also, just so you know, the number of protons stays the same no matter what the positivity or negativity of the atom. It is the number of electrons that defines this.
How do you find the chemical element of an atom?
If you know how many protons the atom has, then that can tell you what element from the periodic table is classifying the atom.
How may electrons neutrons protons are foundin the helium atom?
2 protons 2 electrons 2 neutrons 2 protons 2 electrons 2 neutrons don't know
How do you find the number of protons or electrons in a neutral atom of an element?
in a neutral atom the no.of electrons and protons are the same. so what you have to only know is the atomic no.of that element
What do you know about the numbers of protons and electrons in an atom?
The number of protons defines what element the atom is, and it also defines how many electrons the atom has in its various orbitals in a normal state.There is one electron per proton in an atom in a normal state.
