What describes an atomic number?
Atomic number describes about number of protons.It is equals to number of protons.
What describes an atomic number of an element?
The atomic number of an element is the number of protons in the nucleus of an atom of that element. It determines the unique identity of an element and its position on the periodic table. Elements with the same atomic number belong to the same element, while elements with different atomic numbers are different elements.
What is the identity of an atom with 15 protons?
Elements are identified by number of protons on the periodic table. Number 15 is Phosphorus.
What pieces of information best describes the atomic number of an atom?
The atomic number represents the number of protons in an atom's nucleus, determining the element's identity. It also indicates the number of electrons in a neutral atom. The atomic number is unique to each element on the periodic table and is used to arrange elements in order.
What are the elements in the periodic arranged by?
Number of protons in the atom.
What is the atomic number of an elements based on?
The number of protons in the nucleus of an atom.
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.
The atomic number of an atom or element describes the number of what?
The atomic number of an atom is also known as the proton number. it is, quite simply, the number of protons in the atoms nucleus - as an atom needs to be equally charged, it is also the number of electrons in an atom however, if an atom is radioactive this is not always true.
What does atomic number of an atom or element describes of?
The atomic number tells you how many protons are in an atom. For example, carbon has an atomic number of 6, so it has 6 protons. atomic no. = no. of protons = no. of electrons
What atom has the same number of protons and electrons?
Naturally, all elements have the same number of electrons and protons.
Why is atomic number?
It is about protons in a atom. We use it for idintify elements.
What is the significance of the atomic number of an element?
All elements have protons and electrons. All but hydrogen have neutrons. All elements have isotopes which vary in neutrons but have the same amount of protons as the original element. Different elements never have the same amount of protons so scientists gave these elements their "atomic number" based on the amount of protons the element has. atomic number = amount of protons.
