He said that te three new elements would be discovered, and he described their properties.

Are prediction attempts very successful?
Prediction attempts can vary in success depending on the method used, the specificity of the prediction, and the complexity of the factors involved. Some predictions, especially in controlled environments with clear trends, can be very successful. However, in complex, uncertain, or chaotic situations, predictions may be less accurate.
Which elements did Mendeleev leave spaces?
What Mendeleyev did with the empty spaces was that he left them empty. Say for example, he didn't know Boron, because it wasn't discovered at that time. He left the spot for Boron empty because he didn't know what it was. He predicted that in the future, scientists would find out about new elements, and his predictions were right. That's why, the modern Periodic Table of Elements has more elements that Mendeleyev had put on his list of elements.
Are 3 years greater than 120 months?
No because 3 years equals 36 months which is less than 120 months
Mendeleev's decision to leave gaps in his perodic table was supported by the discovery of?
Yes; in his time not every element was known. As every element in the same column (group) has more or less the same chemical properties, he predicted there should be an element that was not yet discovered at some places. For example, under Silicon, there was a gap where he suspected that, to complete the pattern, a new element was missing; he called it eka-silicon, and correctly predicted many of its properties. The new element was found later, with properties very similar to the predictions; it was eventually called Germanium.
What 5 planets that take less than 29 years to orbit the sun?
Mercury, Venus, Earth, Mars and Jupiter.
What prediction did Mendeleev make that came true in less than 20 years later?
Mendeleev's prediction that there were elements missing from the periodic table was confirmed when gallium was discovered in 1875 and germanium in 1886, fulfilling the gaps Mendeleev had left in his periodic table.
What prediction did Mendeleev make that came true less then 20 yrs later?
he predicted the places where he knew elements should be but he couldn't visibly see. Back when Mendeleev was alive, what you could not see you could not measure. This explains why he couldn't see the noble gasses.
How do you check prediction that a sheet of paper has a mass less that 1 kilogram?
To check if a sheet of paper has a mass less than 1 kilogram, you can use a scale. Place the sheet of paper on the scale and ensure it registers a mass less than 1 kilogram. If the scale reads a mass of less than 1kg, then the prediction is accurate.

What prediction did the students use to test their hypothesis?
The students used the prediction that if they gave plants different amounts of water, then the plants receiving more water would grow taller and healthier compared to the plants receiving less water.
How many years did it take to make the movie new moon?
well the twilight book came out in 2005 so I would of thought about 4 years, and it took less than a year to film the movie.
What is a prediction or explanation that can be tested by experimentation?
A prediction that can be tested is that plants grow taller when given more sunlight. An experiment can be set up with two groups of plants, one receiving more sunlight and the other less, to see if there is a significant difference in their growth. This prediction can be tested by measuring and comparing the height of the plants over a set period of time.
What came first milk or chess?
Milk came first and it came first by a long way. Milk has existed for as long as mammals (with milk producing mammary glands) have existed. This can be counted in the millions of years. Chess came after. It was probably less than 600 years ago that the modern game of chess (that we would recognise as being essentially the same) was invented. If you meant cheese then your spelling needs looking at.
How long did it take to make Halo 2?
Considering how the original Diablo came out in 1996 and Diablo 2 came out in 2000, it probably took 3-4 years to make.
What has the author Margaret Joann Fedje written?
Margaret Joann Fedje has written: 'Prediction of success and failure of freshmen students admitted to Washington State University with less than a 2.5 high school grade point average' -- subject(s): Prediction of scholastic success
What is a prediction or statement that can be tested?
A prediction that can be tested is: "Increasing the amount of fertilizer will lead to higher crop yields." This statement can be tested by conducting an experiment where some crops receive more fertilizer while others receive less, and then measuring the yield of each group to see if there is a difference.
How many people receive vaccinations per year in Australia?
