Mendeleev predicted that gallium (Ga) would have properties similar to those of aluminum, including a relatively low melting point and a density of around 5.9 g/cm³. He also anticipated that gallium would react with water and acids, forming gallium hydroxide and gallium salts. These predictions were later confirmed when gallium was discovered and its properties were studied.

Which is a property that Mendeleev predicted for gallium (Ga)?
Mendeleev predicted that gallium (Ga) would have a relatively low melting point and a density similar to that of aluminum. He also anticipated that it would exhibit properties characteristic of metals, such as being a good conductor of electricity. Additionally, he noted that gallium would have similar chemical properties to those of aluminum, reflecting its placement in his periodic table.
What is Ga(NO2)3?
Ga is Gallium and NO2 is the nitrite anion. Thus, Ga(NO2)3 is gallium nitrite.
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.
What is chemical formula for gallium acetate?
The chemical formula for gallium acetate is Ga(CH3COO)3.
Which element were later discovered that filled in the gaps marked with an asterisk on his table?
The gaps marked with an asterisk on Dmitri Mendeleev's periodic table were later filled by the discovery of several elements, including gallium (Ga), germanium (Ge), and scandium (Sc). Mendeleev had predicted these elements' properties based on the patterns of the periodic table, and their eventual discovery in the late 19th and early 20th centuries confirmed his predictions. This success further validated the periodic law and the organization of elements by atomic weight and properties.
What is a property that Mendeleev predicted for gallium Ga metal gas nonmetal or highly reactive?
Mendeleev predicted that gallium (Ga) would have properties of a metal based on its position in the periodic table. Gallium exhibits characteristics of a metal, such as being solid at room temperature, having a metallic luster, and conducting electricity.
Which is a property that Mendeleev predicted for gallium (Ga)?
Mendeleev predicted that gallium (Ga) would have a relatively low melting point and a density similar to that of aluminum. He also anticipated that it would exhibit properties characteristic of metals, such as being a good conductor of electricity. Additionally, he noted that gallium would have similar chemical properties to those of aluminum, reflecting its placement in his periodic table.
What is the modern name of ekaaluminium?
The modern name of Ekaaluminium is Gallium. Mendeleev discovered Gallium in 1875. He also discovered Ekaboron (now known as Scandium), and Ekasilicon (now known as Germanium).
What is the abbreviation for gallium?
The abbreviation for gallium is Ga.
What is Ga(NO2)3?
Ga is Gallium and NO2 is the nitrite anion. Thus, Ga(NO2)3 is gallium nitrite.
Formula for gallium hypochlorite?
Formula for gallium hypochlorite is Ga(ClO)3.
Why were the elements Ga Sc and Ge important to Mendeleev?
Mendeleev included gallium (Ga), scandium (Sc), and germanium (Ge) in his periodic table because they filled gaps in the sequence of known elements at the time and helped demonstrate the periodicity of their properties. These elements were crucial in showing the predictive power of Mendeleev's periodic table in suggesting the existence of unknown elements and their properties.
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.
What were the three missing elements in the periodic table?
See "Mendeleev's predicted elements" in Wikipedia The answers are: scandium (Sc - 21), gallium (Ga - 31), technetium (Tc - 43), and germanium (Ge - 32) He temporarily named them to be: ekaboron (Eb), ekaaluminium (El), ekamanganese (Em), and ekasilicon (Es).
31 (Ga)?
Gallium
What is Ga NO2 3?
Gallium nitrite (Ga(NO2)3) is a compound formed by the elements gallium and nitrite ions. It is a nitrite salt of gallium, where gallium has a +3 oxidation state. Gallium nitrite is a crystalline solid that is not commonly found in nature.
What is chemical formula for gallium acetate?
The chemical formula for gallium acetate is Ga(CH3COO)3.
