Answer:
Al
Explanation:
Aluminum (Al) is in the same group as Boron (B) so it should have three electrons or dots around it.
Hope that helps.
From mole ratios, the mass ratio of different elements can be predicted. Also the volume can be predicted based on density for liquids and ideal gas law equation for gases. From the mole ratios, the empirical formula can be predicted, as well as the molecular formula given another data which is mass of the sample.
Answer:
We mostly use Kilograms and grams to measure mass =)
