Why are some elements stable on their own while others are more stable in compound?
Some elements are stable on their own because they have a complete outer energy level. These elements are called noble gases. Hydrogen and Helium have a complete energy level with two electrons and all of the other elements are stable with eight. When an element doesn't have a complete outer energy level it is stable in a compound. This is because it is being combined with another element to complete it's energy level.
What predicts that atoms will react with each other to become more stable by filling their valence shells with eight electrons?
the octet rule does
Valence electrons found where?
Valence electron are found in the outer shell of an atom. Depending on the number of valence electrons, the atom is more or less stable: fewer => less stable and more => more stable (inert). Stable = less likely to react with other atoms.
What is The quotient of one number divided by another number?
the amount of times the number being divided by the other number goes in to the other number!
What does the fluorine atom do to become stable unreactive?
The fluorine atom gains one electron to achieve a stable electron configuration, resulting in a full valence shell of electrons. This transforms it into a fluoride ion, which is stable and unreactive.
The product of 9 and another number is 135 what is the other number?
It is 15
Can 0 be divided by another number?
Yes, by every other number.
What is the statement of an atom when most stable when it has eight electrons in its outermost energy level?
The statement is known as the octet rule. Atoms are most stable when their outermost energy level is filled with eight electrons, known as an octet. This stability is achieved by gaining, losing, or sharing electrons with other atoms to complete the octet.
The sum of two numbers is seventy One number is eight more than the other What is the smaller number?
31
Is Neon atomic number 10 stable?
Yes, neon with atomic number 10 is considered stable. It is a noble gas with a full outer electron shell, making it chemically inert and therefore not prone to reacting with other elements.
What is the least common multiple of 5 with another number?
If the other number is not a multiple of 5, the LCM is the product of 5 and the other number.
Why are noble gases stable and unreactive?
Noble gases are stable because they have a complete outer shell - that is, eight valence electrons. Other elements react in order to gain or lose valence electrons, but noble gases are satisfied.
