look at the atomic number...for example, if hydrogen's atomic number's one then it also has one proton.(:

How do you work out how many electrons protons and neutrons an atom has?
if it is a discovered element, look up its atomic number. that is a count of the number of protons in an atom of that element. the number of protons can also be determined by the magnetic charge with no electrons.
How would you figure out how many protons are in an in oxygen atom?
Look at it's atomic number. That shows the number of protons it contains
What gives the number of both the protons and electrons in an atom?
ok so first you look at the atomic #. For helium that is 2. that is the number of protons, and electrons are the same # of protons . long story short, the atomic # is the number of protons which r the # of electrons
Why is 81 the answer to how many protons and neutrons in a thallium atom?
Thallium has 81 protons. Look on the periodic table. Thallium is number 81. That means it has 81 protons.
How can you determine the approximate mass of an atom in atomic mass units?
Number of protons plus neutrons of the most common isotope
How you can determine the number of protons electrons and neutrons an atom has from an atom's mass number and its atomic number?
To determine the number of protons, look at the atomic number. The number of electrons is also the atomic number.To find the number of neutrons subtract the atomic number from the Atomic Mass number.
How do you determine the number of protons in the nucleus?
The number of protons in an atom determines the chemical identity of that atom. (And only that, by the way.) We use the atomic number to state the exact number of protons in all atoms of a given element. Hydrogen has the atomic number 1 because every atom of hydrogen has exactly one proton. Also, every atom with exactly one proton is hydrogen. Helium is atomic number 2, and the same thing applies. All helium atoms have exactly 2 protons, and all atoms with exactly 2 protons are helium atoms. To determine the number of protons in a given atom, look at which element it is and find it on the periodic table or on a list of the elements. Then find its atomic number, which will be the exact number of protons in every atom of that element.
How many protons dose a atom have?
The number of protons in an atom is different for every element. If you look at the periodic table, then the number labeled "atomic number" is the number of protons.
To find what an element of an atom is from you look at the number of?
protons
How do you calculate the number of protons?
you look at either the atomic number or the number of electrons. That's the number of protons.
If an atom is made up of 6 protons 7 neutrons and 6 electrons then what is it's atomic number?
All you need to determine the atomic number is the amount of protons, because it is these sub-atomic particles which enable us to identify an atom. All atoms of the same element have a unique number of protons. In this case, the atomic number is six.
How do you work out how many electrons protons and neutrons an atom has?
if it is a discovered element, look up its atomic number. that is a count of the number of protons in an atom of that element. the number of protons can also be determined by the magnetic charge with no electrons.
How much protons are in oxygen?
Oxygen has 8 protons. The number of protons tell you which number the atom is in the periodic table, so you can just look at the periodic table and the element's number to find out how many protons it has.
What has 30 protons?
Look after atom number 30 in the periodic system
How would you figure out how many protons are in an in oxygen atom?
Look at it's atomic number. That shows the number of protons it contains
How many protons and electrons are in a krypton atom?
Look at the periodic table, do you see the 36 above the Kr? This is the atomic number. The atomic number represents the number of protons in an atom. This number is unique to each element a Kr atom will always have that number of protons.
What atom will be if it has a different number of protons and electron?
a) (well if it has different number of protons or electrons then it would be called an "ionized atom" either positive if more protons or negative if more electrons.) - if there are more neutrons inside the nucleus then protons you got isotopes - b) (well if it has different number of protons or electrons just look at the Periodic Table and count how many protons it has and look at the periodic table that will tell you what an atom will be )
