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: 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

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 human skin cell contains 46 chromosomes. Afrog sperm cell contains 12 chromosomes. Which
pair of numbers shows the chromosome number of
a normal gamete from each of these species?

Answers

The human gamete cells are expected to be 23 chromosomes in number while the gamete cells of a frog will contain 12 chromosomes.

What is a gamete cell?

A gamete cell refers to a reproductive cell in an organism. We must note that the chromosomes in gamete cells are haploid. This means that they only possess half of the normal number of chromosomes.

Now, for humans, the gamete cells will contain 23 chromosomes while the gamete cells of a frog will contain 12 chromosomes.

Sort the given molecules into organic and inorganic substances. C3N2H4 AlBr3 C6H5F CrO3 H2O2 C12H22O11

Answers

We can easily distinguish between organic and inorganic molecules cust by looking at their molecular composition.
Organic molecules are always made out of carbon (C) atoms. Hydrogen atoms (H) are often bound with them in organic molecules, with the addition of other atoms like nitrogen (N), fluorine (F) etc.
So, the organic molecules from the list above are C3N2H4 (imidazole) C6H5F (fluorobenzene) and C12H22O11 (sugar named sucrose) .

The rest of the molecules are inorganic H2O2 (peroxide), CrO3 ( chromium trioxide) and AlBr3 (aluminum bromide)
