Question

ow did knowing the number of valence electrons in one of the alien elements help to identify it? Explain how the table was used to accomplish this task.

Answer 1

Answer:

All elements in the same group of the periodic table have the same number of valence electrons. This made it possible to compare the valence of the alien elements to the valence of elements from our periodic table, and match the alien elements to the correct group. For example, our group 14 elements all have 4 valence electrons, so the alien element with 4 valence electrons had to be part of group 14 also.

Explanation:

Answer 2

• Knowing the number of valence electrons in one of the alien elements helps to identify it because all elements in the same group of the periodic table have the same number of valence electrons which makes it possible to correlate the valence of the alien elements to the valence of elements from the periodic table, and conform the alien elements to the correct group.

• Earth's scientists have declared openly that they have made radio contact with creative life on a foreign planet. One of this alien planet's terminologies has
• been interpreted, and scientific information has started to be exchanged.

• The planet is comprised of the same elements as Earth. Still, the inmates of the planet have various names and symbols for them. Since the alien scientists do not understand the names of our elements, they have relaid the following data on the accepted properties of the elements.

• There are no transitions or unusual earth elements on the alien planet. This implies that their periodic table consists only of the "A" groups of elements.
