Atoms of different elements are built of different numbers of protons, neutrons and electrons.
The most important property is the number of protons, or atomic number, as this defines the element. The number of electrons is equal to this. The number of neutrons can vary but should be given as it defines which isotope you have.
Alternatively, you can express this information as the proton number (i.e. number of protons) and the mass number (protons + neutrons). This latter method is more usual, and the two numbers are often written in front of the element's symbol. The positioning of the numbers is important, with the mass number on top and the proton number below. The script editor won't let me show this, but you'll see it in any chemistry book.
Chemical and physical properties.
A nucliar reaction.
Periodic table
Comparing the properties of the new element with the properties of the other elements in the group we can make this prediction.
An element is a substance that cannot be separated into different kinds of matter.If you could break down a sample of any element into its individual atoms,you would see that its atoms are all the same.Each element is made of only one kind of atom,and its atom differs from the atom of every other element. That difference is what makes the properties if each element unique.
You can use the marbles to resemble the number of protons and neutrons in the specific element.
You could describe its:colourshapesizetexturesmell
A nucliar reaction.
that sounds easy but could you be more specific, which element.

there are many properties of triangles more than i could type there are congruence properties similarity properties and trigonometric properties just to name a few if you have a specific one you would like more information about ask
Could you be more specific? Could you describe the table? On MY table, the turkey is the centerpiece.
Helium is an element that has physical properties. So far it has eluded efforts to make it react with anything else. It could thus be argued it does not have chemical properties other than it is very inert.
You would see which group the element was in and then replace it with another element from the same group, as all elements in a group have similar properties. For example you could replace Sodium with Potassium as they are both in Group 1.
