The element is Cerium. It is in Lanthanide series. Mass number is 140.12
We can find Cerium as a non metal element. Atomic number of it is 58.
the answer is that it is called a atomic number.
Chromium-58 has 32 neutrons. This is calculated by subtracting the atomic number (24) from the mass number (58), which gives us the number of neutrons in the nucleus.
Since chromium has an atomic number of 24, each atom of it contains 24 protons. The number of neutrons can be found by subtracting the atomic number from the mass number. Thus, chromium-63 has 39 electrons.
The elements with atomic numbers 58-71 are called lanthanides, and those with atomic numbers 90-103 are called actinides. These elements are part of the inner transition metals and have unique properties due to their electron configurations.

Cerium was discovered in 1803 Cerium--- Ce atomic number--- 58 atomic mass--- 140.116 # of protons--=58 # of neutrons--- 82 # of electrons---58
the answer is that it is called a atomic number.

Nickel is a metal element. Atomic number of it is 58.

the number of protons in an atoms nucleus is called atomic number
ATOMIC MASS ;The total numbers of protons and neutrons present in the nucleus of an atom is called atomic mass and it is represented by A ATOMIC NUMBER;the number of protons in the nucleus of an atom are called atomic number or proton number and it is represented by Z
The elements with atomic numbers 58 to 71 are called Lanthanides or Lanthanoids. This literally means "Like Lanthanum". They are called this because they have similar characteristics to Lanthanum.
One can ignore the scant contribution of electrons to atomic mass. Simply add the number of protons and neutrons to obtain 53. Please see the link.
