Answer:
1.445 x 10²³ atoms.
Explanation:
- It is known that 1.0 mole of any element contains Avogadro's no. (6.022 x 10²³) of atoms.
<u><em>Using cross multiplication:</em></u>
1 mol of Ag contains → 6.022 x 10²³ atoms.
∴ 0.24 mol of Ag contains → <em>??? atoms.</em>
∴ The no. of Ag atoms in 0.24 mol = (0.24 mol)(6.022 x 10²³ atoms)/(1 mol) = 1.445 x 10²³ atoms.

Answer:
Covalent
Explanation:
Titanium and its first-nearest boron atoms form a strong covalent bond, so TiB2 has high melting point, hardness and chemical stability. Titanium atom releases two electrons to form Ti 2 + ions, and a boron atom gets one electron to come into B- ion
