What is the atomic number and similar elements of xenon?
Xenon is a non metal element. Atomic number of it is 54.
What is Nitrogens atomic number and mass and why does it have that?
atomic mass - 14 atomic number - 7 It has that because it has 7 protons (and electrons) = the atomic number. And it also has about 7 neutrons and roughly, the mass number = the number of neutrons+ the number of protons.
How do you determine how many protons are in an element?
Experimentally, I'm not sure, but I know you can look at your periodic chart, the large number over the symbol of each element is teh number of protons in that element.
What determines the atomic number for hydrogen?
The atomic number of all elements including Hydrogen is detemined by the number of protons it has for example, Helium's atomic number is 2 because it only has 2 protons.
Is golds atomic number 79?
mass number is simply the addition of the proton number and neutron number. we also know that proton number of the element is similar to atomic number. we also know that 79 + (197-79) is the no. of neutron no. of the gold. hence when atomic no. of the gold is 79 its atomic mass or mass number is 197.
Is the number of neutrons equal to the atomic number?
In an atom, the number of protons is always similar to its atomic number. (The number of nutrons may be similar or different.)
How does the atomic mass relate to the atomic number?
These values are similar.
How are Magnesium atomic number 12 and Calcium atomic number 20 similar?
Both have two valence electrons had hence similar properties.
Why can you subtract the atomic number from the atomic mass and get the number of neutrons?
Not the atomic mass but the mass number (of course, these values are similar - not identical).The mass number is the sum between the number of protons and the number of neutrons. As a consequence:Number of neutrons for an isotope = Mass number - Number of protonsThe number of protons is equal to the atomic number.
Why the relative atomic mass is not a whole number?
Bexause its similar with the atomic mass
What is the atomic number and similar elements of xenon?
Xenon is a non metal element. Atomic number of it is 54.
What number of protons in a nucleus in an atom?
The number of protons is similar to the atomic number.
What number does the number of protons plus the number of neutrons give you?
The mass number (similar to the Atomic Mass and not to be confused with atomic number) When the number of protons and neutrons is added the result will be its atomic mass or mass number.
Why are the elements of the periodic table arranged in order of increasing atomic number?
The elements in the Periodic Table are arranged in order of increasing atomic number because it represents the number of protons in the atomic nucleus. It is the number of these protons, and their corresponding number of electrons, that determines the chemical properties of each element. It was found that when the elements lined up, the groups vertically had similar properties. They also increased by atomic mass. The table displays the patterns created by elements of similar properties.
