What known element corresponds to eka-aluminum on the modern periodic table?
Eka-aluminum corresponds to the element gallium on the modern periodic table. Eka-aluminum was a placeholder name given by Dmitri Mendeleev for an element that he predicted would have properties similar to aluminum but with a higher atomic mass. Gallium, discovered in 1875, fits these properties and is known as eka-aluminum's modern counterpart.
What is the pattern between the element calcium and the element gallium?
The pattern between calcium and gallium is that they both belong to the same group on the periodic table, Group 2. They both have similar outer electron configurations and exhibit similar chemical properties in terms of reactivity and bonding. However, they have different atomic numbers and physical properties due to the difference in their atomic structures.
Which element does gallium have more in common with germanium or indium?
Gallium has more in common with indium. Both gallium and indium are part of the same group on the periodic table, Group 13 (or Group IIIA), so they share similar chemical properties and trends. Germanium, on the other hand, is in Group 14 and therefore differs in its properties from gallium.
Is gallium shiny?
Yes, gallium has a shiny appearance similar to shiny metals like aluminum. However, its shiny surface can tarnish quickly when exposed to air.
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 element corresponds to eka-aluminum?
Eka-aluminum corresponds to the element gallium. Gallium is located below aluminum in the periodic table and shares similar chemical properties with eka-aluminum.
What is related to gallium?
Gallium is in group13, (group III) it is more similar to indium than it is to the lighter members of the group, boron and aluminium. It forms two ions, Ga+ and Ga3+ like indium.
What describes mendeleev use of the term eka-aluminum?
Mendeleev used the term "eka-aluminum" to predict the properties of an undiscovered element that would have similar characteristics to aluminum. This was part of his periodic table where he left gaps for undiscovered elements. Eka-aluminum was later discovered and named gallium, confirming Mendeleev's periodic trends.

What is an element related to francium?
Francium is similar to cesium.

Is gallium shiner than aluminum?
After my opinion they are similar.
Is gallium soft or hard?
Gallium is a soft metal, similar to the hardness of common household aluminum foil. It has a low melting point and can easily be cut with a knife.
What elements would you expect exhibit properties most similar to those of aluminum?
The elements immediately above and below aluminum in the same column of a wide form periodic table: boron and gallium. As is usual for relatively light elements, aluminum is more like the element below it, gallium, than the one above it: Aluminum and gallium are both metals, while boron is a nonmetal. In compounds with oxyanions, however, boron is similar to aluminum compounds with oxyanions.
Two element from the boron family?
boron (B), aluminum (Al), gallium (Ga), indium (In), thallium (Tl)
Is gallium shiny?
Yes, gallium has a shiny appearance similar to shiny metals like aluminum. However, its shiny surface can tarnish quickly when exposed to air.
