How many protons does an atom with the atomic number 50 and mass number of 125 contain?
An atom with atomic number 50 contains 50 protons. The mass number of 125 indicates the total number of protons and neutrons combined, so subtracting the number of protons (50) from the mass number gives 75 neutrons.
Neutral atoms contain the same number of protons as?
...the number of electrons. This balance between positive protons and negative electrons gives the atom a neutral charge overall.
Elements are different because their atoms contain different number of?
As the atomic number rises one, one proton, one electron, and a variable amount of neutrons are added.
How do you find the number protons from the atomic number?
Dear Wiki Questioner, The atomic number of an element is defined to be the number of protons its nucleus! Since the most useful characteristics of an element are the result of the number of protons it has, the scientific community chose to order the elements primarily based off of how many protons they contain. So that means that when we are given an atomic number, we automatically are given the number of protons it contains!
How many protons in a isotope of sodium with a mass number of 20?
All atoms of sodium contain 11 protons, since 11 is the atomic number of sodium.
An element is determined by the number of?
An element can be identified by the number of protons in the nucleus of its atoms.
Do all lithium atoms contain the same number of protons?
All the lithium atoms contain the same number of protons.
What atoms of the same element contain the same number?
Atoms of the same element must contain the same number of protons. This is because of the positive charge they provide.
How many protons does an atom with the atomic number 50 and mass number of 125 contain?
An atom with atomic number 50 contains 50 protons. The mass number of 125 indicates the total number of protons and neutrons combined, so subtracting the number of protons (50) from the mass number gives 75 neutrons.
What does the atomic number of an atom made of?
An atomic nucleus contain protons and neutrons; protons and neutrons contain quarks and gluons.
How many protons does promethium contain?
It has 61 protons. The atomic number of an element is the also the number of protons of the element. Hope this helps. :D
Can to different elements contain the same number of protons?
No, the number of protons defines what element an atom belongs to. If two atoms are of different elements then they have different number of protons.
Can the nucleus hold two or more protons?
A nucleus contain protons and neutrons. A nucleus can hold more protons - the number is equal to atomic number.
What atoms of the same element contain the same number of?
protons
A substance whose atoms all contain the same number of protons and the same number of electrons are?
An element is a substance whose atoms all contain the same number of protons and the same number of electrons. The number of protons in an element's atom determines its atomic number and defines its chemical identity.
How many protons does an atom of aluminium contain?
Atomic number of Al is 13. It contains 13 protons.
What particles make up the mass of an atom?
The number of protons
