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.
How is the modern periodic table different from Dmitri mendeleev's table?
Well, honey, the modern periodic table is like the upgraded version of Dmitri Mendeleev's original creation. It's still got all the elements laid out in order of increasing atomic number, just like Dmitri did, but now it's organized based on atomic structure rather than just atomic weight. Think of it as the new and improved model - same concept, but with a few fancy updates.
What are the unknown elements of Mendeleev's Lab of 1869?
Oh, dude, Mendeleev's Lab of 1869 was like the OG chemistry party. The unknown elements back then were basically like the missing guests who RSVP'd but never showed up. It's like trying to throw a surprise party for hydrogen and helium, but they ghost you and leave you with a bunch of uninvited elements crashing your periodic table bash.
What property did Mendeleev use to primarily the elements into a periodic table?
The basic organization structure was by atomic mass, which while it may follow a trend of increasing with each progressing element on the modern table, which is organized by atomic number or number of protons, there are a few exceptions, such as Argon having a greater atomic mass than Potassium, even though Argon has one less proton.
Who was the first person to publish a periodic table?
Dmitri Mendeleev is credited with publishing the first widely recognized periodic table of elements in 1869. He organized the elements based on their atomic mass and predicted the properties of missing elements, allowing for future discoveries.
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 than 20 years?
He said that te three new elements would be discovered, and he described their properties.
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.
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.
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.
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 is the skydriver's acceleration?

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 could you test a prediction?
This is a process wherein a forecast of events is based on observation. Predictions can reliable only when there is regularity in the changes observed. Predictions are also safe if the variables can be controlled or if there are less variables that can possibly affect predictions. One can predict what is to happen at a certain time when predictions are based on observations and past experience. Predictions, therefore, can be within or beyond observed events.Interpolation is a prediction made based on observed data, while extrapolation is a forecast beyond observed data.
