Explanation:
The answer is halogens
Halogens are reactive non metallic elements that form strongly acidic compounds with Hydrogen to form simple salts
Answer:
B
Explanation:
the fluorine has an high tendency to gain electrons from other elements with lower electronegativities
Answer:
<h2>10 g</h2>
Explanation:
The mass of a substance when given the density and volume can be found by using the formula
mass = Density × volume
From the question we have
mass = 2 × 5
We have the final answer as
<h3>10 g</h3>
Hope this helps you
A doesn't change the model, that's what google's for, B can be easily used with the current model, and D is ridiculous.
