The Electronic Structures Of Atoms X And Y Are Shown.X And Y Form A Covalent Compound.What Is Its Formula?A

Answers

Answer 1

Answer:

Its formula is B) XY3,also known as ammonia,because X is hydrogen and Y is nitrogen.

So,yeah the answer is B

Pls mark me as brainliest

Answer 2

The electronic structures of atoms X and Y are shown. X and Y form a covalent compound. The formula is XY₃. The correct option is B.

What are covalent bonds?

Covalent bonds are the strongest bonds present between chemical elements. This bond is formed by sharing electrons between the elements.

Two atoms share electrons with each other and form bonds between them. They are the strongest because there is sharing of electrons between them.

There are five electrons present in the outer shell of the Y atom. There are two atoms more needed to complete the orbital of Y. There is one electron present in the X atom.

Those compounds that are formed by the covalent bond are the strongest compounds. So they are not easy to break them.

Thus, the correct option is B. XY₃.

What are u asking ???

give reason : Inert gas shows least reactivity
pls help

Answers

Answer:

Noble gases also known as inert gases are the least reactive of all known elements because with eight valence electrons, their outer energy levels are full. As a result, noble gases cannot become more stable by reacting with other elements and gaining or losing valence electrons. Therefore, noble gases are rarely involved in chemical reactions and almost never form compounds with other elements.

Explanation:

The only exception is helium, which has just two electrons. But helium also has a full outer energy level, because its only energy level (energy level 1) can hold a maximum of two electrons. A full outer energy level is the most stable arrangement of electrons.

c. atomic mass
d. Overall changes

Answers

Answer:

A. atomic number

Explanation:

the mass number alone cannot uniquely identify an element. But the number of protons in the nucleus identifies it uniquely. In addition, if the atom is neutral, then the atomic number also equals the number of electrons in its orbitals.

history of atomic structure​

Answers

Matter is composed of indivisible building blocks. This idea was recorded as early as the fifth century BCE by Leucippus and Democritus. The Greeks called these particles atomos, meaning indivisible, and the modern word “atom” is derived from this term. Democritus proposed that different types and combinations of these particles were responsible for the various forms of matter. However, these ideas were largely ignored at the time, as most philosophers favored the Aristotelian perspective.
