Answer:
copper
Explanation:
The density of copper is 8.96 g/cm³ and the density of zinc is 7.13 g/cm³.
density= mass/volume
⇒mass = density×volume
For copper,
mass = 8.96 g/cm³ × 1 cm³
mass = 8.96 grams
For zinc,
mass = 7.13 g/cm³ × 1 cm³
mass = 7.13 grams
It is clear that, the mass of copper is more.
Hi there!
I think populations' safety living near nuclear power plants are compromised. If there were a leak, the poison would have a greater potential to kill people living close to the source than farther away.
I think people should be taught and obtain an escape procedure in the event of a nuclear leak emergency. When a leak near them occurs, it is more likely that they can escape faster.
Hope this helps!

Answer:
The compound is most likely to be MgCl2.
Explanation:
Let the element with 2 valence electrons be X
Element with atomic number 17 is Cl.
The compound formed can be obtained as follow:
1. X will lose the 2 valence electrons to form X^2+ as shown below:
X —> X^2+ + 2e- (1)
2. Two Cl atoms will receive the 2 electrons as shown below:
2Cl + 2e- —> 2Cl- (2)
3. Combine equation 1 and 2.
X + 2Cl 2e- —> X^2+ +2Cl- + 2e-
Cancel out the electrons
X + 2Cl —> X^2+ + 2Cl-
X + 2Cl —> XCl2
Now, X is a group 2 element since it has 2 valence electrons. Therefore, X is most likely to magnesium, Mg.
Mg + 2Cl —> MgCl2.
Therefore, the compound is most likely to be magnesium chloride MgCl2
