Answer:
Should be $300
let me know if it's correct:)
Answer: 30
Step-by-step explanation:
105 + 45 =150
180 - 150 = 30
30 +90 = 120
180 - 120 = 60
2x = 60
x =30
I think is the 3rd sorry if I’m wrong
The answer is Beryllium atom has a larger radius by 2 times.
Nitrogen atom: 5.6 × 10⁻¹¹ = 5.6 × 10⁻¹⁻¹⁰ = 5.6 × 10⁻¹ × 10⁻¹⁰ = 0.56 × 10⁻¹⁰
Beryllium atom: 1.12 × 10⁻¹⁰
Since 1.12 is bigger than 0.56, then the radius of beryllium atom is larger of the radius of nitrogen atom. Let's see by how many times:
1.12 × 10⁻¹⁰ : 0.56 × 10⁻¹⁰ = 1.12 : 0.56 = 2
