A nucleus controls most of the cells activities
What else can I help you with?
An electrons path around the nucleus defines its?
An electron's path around the nucleus defines its energy level. The energy levels are quantized, meaning electrons can only exist at specific distances from the nucleus.
What is the number of protons in an atom's nucleus?
The number of protons in a nucleus is called the proton number, or atomic number. It is what defines which element we have.
What is the number of protons in an atoms nucleus?
The number of protons in a nucleus is called the proton number, or atomic number. It is what defines which element we have.
Every atom of the element carbon has the same number of?
protons in its nucleus, which defines the element.
What defines the mass number of isotope?
The mass number is the total weight of neutrons and protons in the nucleus of an atom.
How many protons are in the nucleus of Iodine-131?
The atomic number of iodine is 53 so there are 53 protons in the nucleus, irrespective of which isotope you are considering. 53 is the atomic number and defines iodine.
What is the term that defines the areas of electron density around a nucleus?
The term that defines the areas of electron density around a nucleus is the electron cloud or electron shell. These shells represent different energy levels or orbitals where electrons can be found. Each shell can hold a specific number of electrons.
What is an atomic number and how is it used to distinguish one element from another?
It is the number of protons in the nucleus of an atom. It defines what element the atom is.
What configuration defines an isotope of the same element?
Isotopes of one particular element differ only in their number of neutrons in nucleus.
What property defines a specific element?
Its atomic number; i.e., the number of protons in the nucleus of its atoms.
Does each element have its own atomic number?
Yes. The atomic number of an atom is the number of protons in its nucleus, which actually defines which element it is.
What particle defines an element?
The number of protons in an atom's nucleus determines the identity of element. The number of protons equals the atomic number.
