What makes the Noble Gases the least reactive elements on the periodic table?
They all have one valence electron in their outer shell.
They all have seven electrons in their outer shell.
They all have eight valence electrons in their outer shell.
All of the elements have a full outer electron shell.
sorry im slow yall
The reason the Noble Gases, the least reactive elements on the periodic table, are they all have eight valence electrons in their outer shell. The correct option is C.
What are noble gases?Noble gases are the gases of the periodic table that contain a fully filled last orbital with electrons, that is why they are called noble gases. These gases are helium (He), neon (Ne), argon (Ar), krypton (Kr), xenon (Xe), and radon (Rn).
Noble gases are the least reactive elements because they have fully filled the last orbital, which means they do not need any electrons from others, nor do they have to donate any electron to fulfilled their orbitals.
Elements react with each other by sharing electrons with each other. They either donate or accept electrons from others and form bonds with each other.
Thus, the correct option is C. They all have eight valence electrons in their outer shell.

Use this picture to explain that an electrically charged object can attract an uncharged object without any contact. Your answer should be at least three sentences long.
a balloon hanging from a string with small pieces of paper stuck to the bottom of it, with a few pieces on the ground
Answer:
Charges: positive and negative
Explanation:
When we put a charged object near an uncharged object, it produces opposite charges in the near end of the uncharged object by electric induction. In the figure, we can see that the ballon has charges which produces opposite charges in the paper which is uncharged

The force that holds two atoms together is called a(n) _______
gravity
nuclear force
reaction
chemical bond
The force that holds two atoms together is called a chemical bond.
What is a chemical bondA chemical bond is a force of attraction that holds two or more atoms together to form a stable molecule or compound. Atoms consist of a positively charged nucleus containing protons and neutrons, surrounded by negatively charged electrons. In order to achieve a stable electronic configuration, atoms can undergo chemical bonding to fill their outermost electron shells.
Chemical bonds play a vital role in determining the physical and chemical properties of substances. The strength and type of bond between atoms influence factors such as boiling points, melting points, solubility, and reactivity. Understanding chemical bonds helps explain how different substances interact and form new compounds.
