Answer:
its A
Explanation:
The definition of color is a component of light which is separated when it is reflected off of an object. The appearance of objects or light sources described in terms of the individual's perception of them, involving hue, lightness, and saturation for objects, and hue, brightness, and saturation for light sources.
Answer: Another useful feature of the periodic table is that most tables provide all the information you need to balance chemical reactions at a glance. The table tells each element's atomic number and usually its atomic weight. The typical charge of an element is indicated by its group.
Explanation:
1 elements
2 they have same number of valence electrons
3 period
Answer:
d. its effective nuclear charge is lower than the other noble gases.
Explanation:
Xenon belongs to group O on the periodic table. Most of the elements here are unreactive.
Due to the large size of Xenon, the outermost electrons have very low effective nuclear charge. Effective nuclear charge is the effect of the positive charges of the nucleus on the electrons in orbits. This effect decreases outward as atomic shell increases.
Xenon has a very large atomic radius and there is weak a nuclear charge on the outermost electrons. The more electronegative elements would be able to attract some of its outermost electrons easily and form chemical bonds with xenon much more readily.
The solution for problem 36 is in the picture attached. I am 80% sure it’s correct.
