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).

In protostome development, there is a spiral radical and indeterminate cleavage. The blastopore becomes the mouth and the coelom forms from the mesoderm.
In deuterostomes development, radial and indeterminate cleavage takes place. The blastopore is the new anus and the coelom forms from budding off the wall of the archenteron.
Final answer:
The main difference between protostomes and deuterostomes is the sequence in which the mouth and anus develop during embryonic development. Protostomes develop a mouth first, and deuterostomes form an anus first.
Explanation:
The primary difference between protostomes and deuterostomes lies in the sequence of their embryonic development.
Protostomes, which include organisms like insects and mollusks, follow a developmental sequence where the first opening in the embryo becomes the mouth, and the second becomes the anus.
On the other hand, deuterostomes, including organisms like vertebrates and echinoderms, have a developmental sequence where the first opening becomes the anus, and the second becomes the mouth.

We cannot store up amino acids on our body, but we can have amino acids through consumption of food. These amino acids of which the body cannot make is called as essential amino acids.
