Explanation:

\huge\star\underline\mathfrak\green{Follow\:me}

➡️ c option is correct.

\huge\star\underline\mathfrak\green{</strong><strong>Expl</strong><strong>anation</strong><strong>}

➡️ Based on other elements in the same group he predicted the existence of eka-aluminum, eka-boron, and eka-silicon, later to be named gallium (Ga), scandium (Sc), and germanium (Ge). Mendeleev predicted the atomic mass of each element along with compounds they each should form.

➡️ 5th period and 6th group..

\huge\star\underline\mathfrak\green{</strong><strong>Exp</strong><strong>lanation</strong><strong>}

➡️ Now you know about periods going left to right. The periodic table also has a special name for its vertical columns. Each column is called a group. The elements in each group have the same number of electrons in the outer orbital.✔️✔️✔️
