Sodium Chloride is a white crystaline solid formed when the highly reactive metal Sodium reacts with the poisonous greenish yellow gas Chlorine.
Dmitri Menedeleev was able to predict the properties of undiscovered elements because the periodic table organizes elements based on repeating properties. For example, all of the Noble Gases (the far-right column) have filled their valence electron shells and are inert gases. One could reasonably assume that if a new element was discovered that went in the noble gas column that it would be inert as well. Mendeleev used this concept to accurately predict the properties of a handful of undiscovered elements, such as Gallium and Germanium.
well, basically the elements in the modern periodic table are arranged in the increasing order of atomic number. the elements are arranged in a group according to the valance electron. all elements in a group have same valance number of electron making the elements in group possess similar properties. further more as we go down the periodic table metalic character increases...
Depending on the block it may be increasing or decreasing acidity, atomic radii varies through periods, atomic number increases by 1 with each element, ... as to reactivity, elements of lower periods are almost all radioactive, as with a heavier nucleus nuclear stability decreases. Hope this answers your question! :D
the five themes and the six elements could help me by separating the different categories in geography and making things easier

he properties of salts are different from the properties of elements that go into making them
All elements are different from each other, that is why they are called elements. They have a different number of subatomic particles making them different.
Different elements are known by their atomic number, the number of protons or the number electrons making up the atom. This gives them the electrical and physical properties by which they are identified when in large enough quantity to be noticed.
I really do not know what the answer for this question is.
Atoms of different elements can " stick together " ( making compounds ) via elements sharing or trading arrangements called
metalloids also called semiconductors, ae elements that have properties of both metal and nonmetals.
At that time, scientists knew some of the properties of more than 60 elements. However, no one had organized the elements according to these properties; making it harder for scientists to understand how elements interact with each other.
they combine with themselves atoms of different elements connot combine with each other wothout making a new molecule
It is a steel making stage in whice steel refined and different elements are added in it.
Because different materials have different properties, and designers like to pick the ones best suited for the task.
