The atomic number of am element is determined by its number of either electrons or protons, hence here, it is 18. Therefore the element must be argon which the isotope has mass number 38, as there are 18 protons and 20 neutrons.

How many electrons protons and nuetrons are in the element tungsten?
protons= 74 neutrons= 110 electrons= 74
How many protons neutrons and electrons are in aluminum?
,Aluminium ; from the Periodic Table its atomic no. is 13. Its atomic mass is 27. From the information we can deduce ;- #1 ; The number of protons is '13' #2 ; the number of electrons is '13' #3 ; the number of neutrons is '27-13 = 14'. Remember for all elements, the number of protons and electrons is the same as the atomic number ; its position in the periodic table. Remember to, for all elements, if you subtract the atomic mass from the atomic number , then answer id the number of neutrons in the most common isotope.
What does the number of protons in an atom also tell you?
The number of protons in the nucleus of an atom tell you which element you are dealing with. It is the number of protons in an atomic nucleus that determines the elemental identity. Only that. The atomic number of an element is the number of protons you will find in the nucleus of every atom of that element, regardless of the number of neutrons or electrons involved.
As the number of the isotopes of an element increases the number of protons?
Atomic mass increases with the ordered placement of the element of the periodic table. Conveniently, the number of protons, nuetrons and electrons also increase with numbered order on the table. Every element is assigned a number. This number is equal to the number of protons, nuetrons and electrons. I believe it's the nuetrons that make up the mass of the element, but not sure!
What is the number of neutrons in magnesium 24?
The # of nuetrons in any element is the Atomic Mass - the # of protons In this case the atomic mass was 24.3 minus the protons (12) equals 12
How do you calculate the amount of protons or neutrons in an element?
well you look at the periodic table of elements. the atomic number equals the number of protons. Then subtract the number of protons from the atomic mass (both protons and nuetrons have atomic mass units of 1 and electrons equal 0). That will give you the number of nuetrons.
How many electrons protons and nuetrons are in the element tungsten?
protons= 74 neutrons= 110 electrons= 74
What is the number of protons and nuetrons for aluminum?
The atomic number of aluminium is 13. So it has 13 protons and 13 electrons.
The atomic number of an element is what?
The atomic number of an element is how many protons and electrons (you must have the same amount of protons as electrons) an element has in it's nucleus. The Atomic number= number of protons= number of electrons.
What is the relationship between mass number and atomic numbers?
Atomic number is the number of protons in the nuclei of the atoms of an element. Each element has a unique atomic number. Mass number is the number of protons and neutrons in the nuclei of the atoms of a specific isotope of an element.
What is the atomic mass the same as?
The Atomic Mass is equal to the number of protons and electrons that an element has.
How many protons nuetrons and electrons does yttrium have?
Look at the atomic number. That will be the number of protons and electrons; subtract that number from the atomic mass (rounding down) and you'll have the number of neutrons.
How many protons neutrons and electrons are in aluminum?
,Aluminium ; from the Periodic Table its atomic no. is 13. Its atomic mass is 27. From the information we can deduce ;- #1 ; The number of protons is '13' #2 ; the number of electrons is '13' #3 ; the number of neutrons is '27-13 = 14'. Remember for all elements, the number of protons and electrons is the same as the atomic number ; its position in the periodic table. Remember to, for all elements, if you subtract the atomic mass from the atomic number , then answer id the number of neutrons in the most common isotope.
What is The atomic mass of an element is equal to?
The number of protons, electrons, and neutrons:P
What does the atomic number tell us?
it tells us the number on the periodic table and it also tells us how many protons and nuetrons and electrons are in the atom within the nuecles.
What can be determined by looking at the atomic number of an element?
the number of protons in an atom and the number of electrons in an atom
How many protons nuetrons and electrons does copper have?
Copper has 29 protons, that is why it has the atomic number of 29. In addition, copper has 29 electrons and 35 neutrons.
