The close match between Mendeleevs prediction and the actual properties of new elements showed how usefullhis pariodic tabel could be.
Mendeleev had some empty spaces in his table. On being asked why he left spaces, instead of seeing it as a drawback, he confidently said that those were the places for "yet to be discovered elements". He named them by prefixing the Sanskrit numeral "Eka-" to the preceding element.For example, he named Gallium as "Eka-aluminium", Germanium as "Eka-Silicon" and so on. Later, when a new element was found and was named as Gallium, it was observed that it had almost same properties as that of Eka-Aluminium predicted by Mendeleev. As his predictions were almost accurate, other scientists began to accept that his classification was indeed better than any others'. And so, it was accepted.
"I accept your proposal on condition that I keep my present position!" is an example of a conditional acceptance.
The acceptance of a job offer through mail takes effect when both parties agreed on the offers. This means that the corporation must have received the acceptance letter and has verified with the sender before the job offer will take effect.
