Mendeleev predicted the properties of eka-aluminum (now known as gallium) based on its position in the Periodic Table and the trends he observed in neighboring elements. He anticipated that eka-aluminum would have an atomic weight of around 68, a density similar to that of aluminum, and exhibit characteristics such as being a metal with a low melting point. When gallium was later discovered, its properties matched Mendeleev's predictions closely, confirming his foresight regarding the periodic relationships among elements.

Which matches mendeleev prediction of the properties of eka-aluminium?
Mendeleev predicted the properties of eka-aluminium, which we now know as gallium, based on its position in his periodic table. He anticipated that eka-aluminium would have an atomic weight of about 68, a density of approximately 5.9 g/cm³, and would form compounds similar to aluminium, such as a trichloride. When gallium was discovered, its properties closely matched Mendeleev's predictions, confirming the validity of his periodic table and the existence of undiscovered elements.
Which scientist placed the periodic table in order of the number of protons in the atom?
Dmitri Mendeleev, a Russian chemist, organized the periodic table in the manner that we know today. Initially, he organized them by increasing atomic mass, but that caused a few mis-matches. Later, he re-organized them by increasing atomic number, and it made more sense. His organizational skills helped us to predict the properties of elements unknown during his time. Turns out they fit right in where they should, upholding his brilliant creation.
Why can a magnetic attract pins but not matches?
Magnetic materials like pins have unpaired electrons that align with an external magnetic field, causing attraction. Matches do not contain magnetic properties, so they are not affected by magnetic fields.
Non metal used in matches fertilizers and detergents?
Phosphorus is the non-metal used in these three substances. Phosphorus is in Group 15 on the periodic table. It also has the atomic number of 15.
What element is known as the bringer of light and used on the tips of matches?
Sulphur is the material used on the tips of matches. They used to be known as Lucifer matches.
Which matches Mendeleev's prediction for the properties of eka-aluminum?
Eka-aluminum corresponds to gallium, which was discovered later by Lecoq de Boisbaudran. Gallium's properties closely match Mendeleev's predictions, such as its atomic weight and properties lying between aluminum and indium in the periodic table.

Which matches Mendeleevs prediction for the properties of eka-aluminum?
It would be a soft metal with a low melting point.
Why did mendeleev live some spaces in his periodic table?
During Mendeleev's time, not all of the elements had been discovered. He organized his table in such a fashion that the rows held similar properties. Also, the table was in order of Atomic Number. He knew that some elements had different properties then those next to them so he moved them down until he found it's matches.

How do you do the aunt Stella card trick?
The Aunt Stella card trick involves a simple yet effective method of prediction. First, you ask a participant to select a card from a standard deck and remember it. After they return the card to the deck and shuffle it, you reveal a previously written prediction that matches their chosen card. The trick relies on a clever setup, often using a marked deck or a specific arrangement, allowing you to know their card without them realizing how.
