What makes the elements in the periodic table different from each other?
The number of protons in the nucleus or the number of electrons surrounding the nucleus. This number is also called atomic number of the element.
What is the definition for number of protons in the nucleus of an atom?
The number of protons in neutrons in the nucleus of an atom is defined as atomic mass. The average atomic mass for all the isotopes of an element is given as the element's atomic weight. This is why atomic weights are decimal numbers.
What particle in an atom makes each elements unique?
in an atom protone makes the each element unique
How can some elements have the same atomic number?
No two distinct elements have the same atomic number. The atomic number is the number of protons an element has and is what makes it that particular unique element. Isotopes do have the same atomic number however they belong to the same element because an isotope is just a form of the element with more or less neutrons in the nucleus, not a different element. An example would be Hydrogen, it has three Isotopes: Hydrogen-1 its nucleus is composes of just a single proton. Hydrogen-2 or deuterium has a proton and a neutron in its nucleus. Hydrogen-3 or tritium has a proton and two neutrons in its nucleus. Notice that they all have just one proton, this by definition makes them all hydrogen atoms, and considered to be the same element.
What makes atoms of one element different from atoms of all elements?
The only thing that makes an atom is the number of protons it has. e.g Hydrogen always has 1 proton, Lithium has 3 protons. This is represented as the relative atomic number. Don't get confused with neutrons though. All elements can have different numbers of neutrons and these are called isotopes. But no matter what if you've got 3 protons you are always Lithium.
Does the number of neutrons in the nucleus of an atom give it a unique chemical nature?
The number of protons is most important as this defines the atom's atomic number and it's place in the periodic table of elements. The number of neutrons only makes for isotopes of the atom. That means carbon, for example, can have 12 neutrons in its most common form but can also have 13 neutrons. Whether it has 12 or 13 does not matter - it is still carbon. It is carbon because it has 12 protons.
What makes atoms of different elements different from one another.?
The number of protons in the nuclei of their atoms. This is the atomic number of an element and each element has its own unique atomic number.
What makes two elements distinct?
Only their no of protons in nucleus (atomic numbers)
What makes trans-uranium elements radioactive?
Transuranium elements are radioactive and unstable; the stability of a nucleus is a problem of nucleon physics.
What makes atoms and elements alike?
both have a nucleus of protons and neutrons and outer orbits of electrons
What makes inert gases unique?
They don't react with any other elements.
What makes up an atomic?
"number of protons in an atomic nucleus"
