Which element has an atomic number between 27 and 31?
Atomic number 27 : Cobalt Atomic number 28 : Nickel Atomic number 29 : Copper Atomic number 30 : Zinc Atomic number 31 : Gallium
What is the atomic number of NA plus 1?
11...There are 11 electrons in Na1+ the only difference between Na1+ and Na is Na1+ has 1 more proton...there is no difference in electrons. Hope this helps :)
What do you get if you subtract the atomic number from the mass number for a particular atom?
You get the number of neutrons in the atom. The mass number represents the total number of protons and neutrons in the nucleus, while the atomic number represents the number of protons. Subtracting the atomic number from the mass number gives you the number of neutrons because the difference accounts for the protons.
What is the relationship between the atomic number of protons and the atomic number?
The atomic number and number of protons are always the same in a normal element.
Explain how chemists can state with certainty that no one will discover an element between sulfur and chlorine?
Chemists can state this with certainty because the periodic table follows a specific pattern in terms of atomic number and electron configuration. All elements have been discovered up to atomic number 118, and there are no gaps between sulfur (atomic number 16) and chlorine (atomic number 17) in the periodic table, indicating that no elements are missing between them. This knowledge of the periodic table's structure allows chemists to confidently assert that no new element will be found in this region.
What best describes the number of neutrons in an atom?
It is equal to the difference between atomic number and Atomic Mass number. A+
Explain what evidence is available on the periodic table that supports the idea of isotopes?
the difference between the atomic number and the average weight
Explain the difference between atomic mass and atomic number?
Atomic mass represents the total mass of an atom, combining the mass of protons, neutrons, and electrons. Atomic number, on the other hand, is the number of protons in the nucleus of an atom, which determines its chemical properties and element identity.
What is the difference between the atomic number an its atomic mass?
Atomic number is the amount of electrons. Atomic mass is the amount of protons and neutrons.
What is the difference between number of protons and neutrons and atomic number?
g
What is the difference between americium and neptunium?
Neptunium has the atomic number 93 and americium has the atomic number 95.
What is an element with 20 neutrons?
Calcium-40: The atomic number of calcium is 20 and the number of neutrons is always the difference between the atomic mass and the atomic number.
What is the difference between the atomic number and the valence number of an atom?
Describe the reactivity of halogens
What is the difference between atomic number and atomic mass weight?
Atomic mass is the mass of an atom in atomic mass units, and includes protons, neutrons, and electrons; and atomic number is the number of protons in the nucleus of the atom.
What is the difference between the atomic number mass number and atomic mass?
We can find Atomic Mass and mass number in chemical elements. Atomic mass is about weight of the atom. Mass number is about total of neutrons and protons.
How do you explain what does the atomic number stands for?
The atomic number is the number of protons in the atom.
What is the difference between the atomic number and average atomic mass?
We can find Atomic Mass and mass number in chemical elements. Atomic mass is about weight of the atom. Mass number is about total of neutrons and protons.
