∙ 10y agodepends on the atom... Ordinary matter is made up of protons, neutrons, and electrons and is composed of atoms. An atom consists of a tiny nucleus made up of protons and neutrons, on the order of 20,000 times smaller than the size of the atom. The outer part of the atom consists of a number of electrons equal to the number of protons, making the normal atom electrically neutral.
A chemical element consists of those atoms with a specific number of protons in the nucleus; this number is called the atomic number. The atoms of an element may differ in the number of neutrons; atoms with different neutron numbers are said to be different isotopes of the element.
Elements are represented by a chemical symbol, with the atomic number and mass number sometimes affixed as indicated below. The mass number is the sum of the numbers of neutrons and protons in the nucleus.Oxygen, hydrogen, nitrogen are all elements.

What elements have atomic number?
All chemical elements have atomic numbers.
How are elements arranged on todays periodic table?
The elements are arranged with increasing atomic number
How do you find out the atomic number of an element?
Atomic number is the no. of protons or no. of electrons in an atom .
Are elements in a period arranged alphabetically?
Yes, the periodic table is arranged in order of increasing atomic number. An element's atomic number is a count of its number of protons. If you arrange the elements in this way, certain properties become recurring, or periodic, which is why it's called that.
What role does the atomic number play in the periodic table of elements?
elements are listed in the periodic table in order of increasing atomic number
A difference in the atomic number of atoms means the atoms are of same or diffierent elements?
Different atomic numbers represent different elements.
What can all elements be identified by?
Their atomic number, which represent the number of protons in the nucleus. This will also be the number of electrons in the unionised state of the atom.
Does chloroform have a atomic number?
No it does not have. Atomic number i for elements.
What elements have atomic number?
All chemical elements have atomic numbers.
Are the elements listed in order of atomic number or atomic mass?
Atomic number.
How are elements arranged on todays periodic table?
The elements are arranged with increasing atomic number
What is the relationship between the atomic number and the elements identity?
Every elements has atomic number, elements identity determined the number of protons in its nucleus.
How do you find out the atomic number of an element?
Atomic number is the no. of protons or no. of electrons in an atom .
How are the elements arranged in the periodic table by atomic mass or atomic number?
Atomic Number
Atomic number of protons?
protons dont have an atomic number as they are not elements
What are the 10 elements with atomic number?
all element have an atomic number.
Can elements be ordered by there atomic number?
Yes. The atomic number is how they are ordered.
