What do all elements in a column in the periodic table have in common?Their atoms have the same number of valence electrons.

Their atoms have the same atomic mass.

Their atoms have the same number of protons and electrons.

Their atoms have the same number of neutrons.

Answers

Answer 1

Answer:

Answer: Option A

Explanation:

The elements are arranged in a periodic table based on their properties. The group of similar elements share common characteristics and hence kept in the same periods.

The elements having same number of valence electrons in their outer shell. As they have same number of valence electrons they have similar properties in terms of reactivity, stability, et cetera.

Hence, the correct answers is option A

Answer 2

Answer:

All elements in a column in the periodic table, their atoms have the same number of valence electrons. (Option A)

What is the arrangement of elements?

In the periodic table, elements are organized into columns called groups or families.

Elements within the same group have similar chemical properties because they have the same number of valence electrons.

Valence electrons are the electrons in the outermost energy level of an atom, and they play a crucial role in determining an element's chemical reactivity and bonding behavior.

While elements in the same group have similarities in terms of valenceelectrons, they may have different numbers of protons and electrons (giving them different atomic numbers and overall electrical charge) and different numbers of neutrons (giving them different isotopes with varying atomic masses).

A. It causes the reproductive system to stop functioning.
B. It causes the liver to stop functioning.
C. It destroys red blood cells.

Answers

C. It destroys red blood cells.

Answer:

C. it destroys red blood cells

Explanation:

When Plasmodium sporozoites enter the body, they infect the liver. New cells called merozoites emerge from the liver and infect red blood cells. The merozoites eventually burst from the red blood cells, destroying them and releasing toxins that cause various symptoms.

The digestive system contains a variety of parts that perform specific functions within the body. The small and large intestines have some similarities and some differences. Which function is only performed in the small intestine?

Answers

In the digestive system, the food and theproducts of digestion pass through the muscular tube known as intestine. It extendsfrom the lower end of the stomach to the lower opening tract of the digestivetract or the anus. The intestine is divided into two sections, the small andlarge intestine. Although both parts receive the digestion and product of thefood, they differ in some areas. For the small intestine, its main function isto carry out most of the digestive process such as absorbing the entirenutrient you get from foods into your bloodstream. This function is not presentin the large intestine because the digested food is mixed with the digestivejuices form the small intestine and no nutrients left for the large intestineto handle.

Answer:

mineral absorption
