What element is composed of atoms that all have the same atomic number?

All elements are composed of atoms that all have the same atomic number. If the atomic number is different then you have a different element. The number of neutrons can be different and you will have a different isotope of that element with a different mass. An example of an element that only has one isotope is fluorine.

What is a unique substance composed of atoms have the same atomic number?
I believe that is the definition of an element. true
What is the atomic number of Ethane?
Ethanol is a compound, not an element and so does not have an atomic number. It is composed of the elements carbon, hydrogen, and oxygen which have the atomic numbers 6, 1, and 8 respectively.
The atomic number determines the what?
The number of protons.
What are elements composed of?
Elements are composed of atoms, which are made up of: protons,neutrons, and electrons. The number of protons in one atom of an element is equal to the periodic number of the element. If the element is in it's standard state(has no charge), then the number of electrons are equal to the number of protons. the number of neutrons can be determined by taking the atomic mass and subtracting the number of protons.For example 1 K (Potassium) atom has:19 Protons20 Neutrons19 Electrons
Which element's atoms contains twenty nine protons?
It is element 29 on the periodic table. The elements in the periodic table are arranged according to increasing atomic number. The atomic number is the number of protons in the element's atoms.
What is a unique subtance composed of atoms having the same atomic number?
A element is a unique substance that is composed of atoms having the same atomic number. Energy is the ability to do work.

Is and atom and an element the samething?
No. Atoms are the building blocks of matter. Each element is composed of the same kind of atoms, according to their number of protons (atomic number). Molecules are composed of two or more atoms (they may be the same element or different elements), and compounds are composed of two or more kinds of atoms.
What does an element's atomic number stand for?
Atomic number is the number of protons in the atomic nuclei of the atoms of an element.
Is a sample composed of atoms only having the same atomic number an isomer?
No. (Element is the word you're looking for.)
Are all sample of elements are composed of atoms with same atomic mass?
All atoms in a pure sample of one element have the same mass. The atoms in a different element have a different mass. Different atoms is what makes different elements.
What is the atomic number of atoms?
how do you find the atomic number for an element?
Do all atoms of any one element have the same atomic number?
An atomic number is actually related to an element and not an atom. Therefore, the question is not relevant. It is NOT atoms that have an atomic number; it is the element.
What Atomic particle controls its reactivity?
The number of protons in the nucleus will ALWAYS be the same for a specific element.(ex: Hydrogen always has EXACTLY 1 proton)But, the number of electons and neutrons can vary in a particular element.
Is the atomic number?
Atomic number is the number of protons in the atoms of a particular element. Each element has its own unique atomic number.
How are atomic number and atomic mass alike?
Atomic number and atomic mass are not alike. Atomic number is the number of protons in the nuclei of the atoms of an element. Each element has a unique atomic number. Atomic mass is the combined masses of the protons, neutrons, and electrons of the atoms of an element. Individual isotopes of an element have specific mass numbers, which are the sum of the protons and neutrons in the nuclei of the atoms of the isotope.
Form a atomic number of 15 atoms?
Atomic number is the number of protons in an atom, not the number of atoms. The element with the atomic number 15 is phosphorus.
