Question

the table below lists information about two common types of nuclear radiation. fill in the missing information. note: round masses to the nearest atomic mass unit (u). table with columns: name, matter or energy?, mass (u), charge (e), can be stopped by; rows with dropdowns and radio buttons for selection, and input boxes for mass and charge for alpha and another radiation type

Explanation:

Step1: Identify the first row

The first row has mass \(0\) u and charge \(0\) e. This is characteristic of gamma radiation. Gamma radiation is energy (electromagnetic radiation). It can be stopped by thick lead or concrete.

Step2: Analyze the alpha row

Alpha particles are matter. An alpha particle is a helium - 4 nucleus (\(^{4}_{2}\text{He}\)). The mass of a helium - 4 nucleus is approximately \(4\) u (since \(m = 4.0026\) u \(\approx4\) u). The charge of an alpha particle is \(+ 2e\) (because it has 2 protons). Alpha particles can be stopped by a thin sheet of paper.

Answer:

name	matter or energy?	mass (u)	charge (e)	can be stopped by
alpha	matter	\(4\)	\(+2\)	a thin sheet of paper
