We know nickel is a transition element. We also know aluminum is a poor metal, as it gallium. Tellurium is a metalloid.
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.
Dmitri Mendeleev was a Russian chemist who created the periodic table. The term "Eka aluminum" refers to the element gallium, which he predicted would exist based on gaps in the periodic table and similarities with aluminum. Mendeleev's predictions were accurate and gallium was discovered later.
Gallium is a metal. It is next to germanium, a semi-metal.
The element is Mk, or in real terms, mickey mouse
"Family" in this context usually means a column of a wide form Periodic Table. With this meaning, the other elements in the boron family are aluminum, gallium, indium, and tellurium.
Eka-aluminum corresponds to the element gallium. Gallium is located below aluminum in the periodic table and shares similar chemical properties with eka-aluminum.
I believe Gallium
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.
Boron, silicon, germanium, arsenic, antimony, and tellurium are recognised. These elements include, hydrogen, beryllium, nitrogen, phosphorus, sulfur, zinc, gallium.
The element that is 4 letters and starts with an L is Lead (Pb).

The element of gallium is Ga3.
