Answer:
1. Nonmetal
2. Nonmetal
3. Covalent
Explanation:
CH4 is the chemical formula for the methane molecule in which four atoms of hydrogen is chemically bonded to one atom of carbon. Both carbon, which is the first element and hydrogen the second element are non-metals, and hence can only form a covalent bond.
A covalent bond is a type of chemical bond in which two atoms share their valence electrons. It occurs between two non metallic atoms. In this molecule, CH4, carbon and hydrogen share their valence electrons to form a covalent bond.
Answer:
3.27 x 10⁻¹⁶ grams
Explanation:
moles Au = 1.00 x 10⁻⁶ Atoms / 6.02 x 10²³Atoms / mole = 1.66 x 10⁻¹⁸ mole Au
grams Au = 1.66 x 10⁻¹⁸ mole Au x 196.97 grams Au/mole Au
= 3.27 x 10⁻¹⁶ grams Au
