Answer OWN WORDS

Thanks

1. The elements gallium (Ga) and germanium (Ge) were discovered later in Mendeleev’s lifetime, after he had already constructed his model of the periodic table. How did he know where these elements fit in his periodic table of the elements?

2. What properties do the elements of zinc (Zn), silver (Ag) and titanium (Ti) have in common, and where are they found on the periodic table?

3. Where do you find the elements with the greatest atomic size, least electronegativity, and the least ionization energy in the periodic table? How would you classify the elements with these properties (metals, nonmetals, or metalloids)?After you have classified the elements, describe some of their properties.
