Yes, the statement is true because chemical bonds formed by sharing or transferring outermost electrons of an atom.
Why inner shells are not shared?Inner shell electrons are not shared between atoms when they form chemical bonds but the outermost electrons can form bonds with the atoms because they are easy to lose and share.
So we can conclude that the statement is true because chemical bonds formed by sharing or transferring outermost electrons of an atom.

7. Which element in period 5 has properties similar to barium?
In order for the process to be endothermic, the energy required to break the lattice has to be _______ than the energy released as the ions go into solution.
a. Greater
b. Less
Explanation:
I honestly believe the answer is greater
If the energy required to break the lattice is less than the energy released as the ions go into solution, then the dissolution of solute is endothermic.
An endothermic reaction is one in which energy is absorbed. This implies that the energy change of the reaction is positive.
Now, if the energy required to break the lattice is less than the energy released as the ions go into solution, then the process is endothermic and energy is absorbed.

What is the ratio of the effusion rate of the helium to methane? (round to hundreds)
Answer:
2.00
Explanation:
From Graham's law; the rate of effusion is inversely proportional to the square root of the relative molecular mass.
Let the rate of effusion of Helium be R1
Let the rate of effusion of Methane be R2
Let the molecular mass of Helium be M1
Let the molecular mass of Methane be M2
Hence;
R1/R2 = √M2/M1
R1/R2 = √16.0294/4.0026
R1/R2 = 2.00
How can scientists use stoichiometry to ensure that commercial products contain the components that manufacturers claim they do?
Answer:
I know you have been waiting awhile for this question to be answered :)
Stoichiometry is used in industry quite often to determine the amount of materials required to produce the desired amount of products in a given useful equation. Each one of these products requires stoichiometry. There would be no products from these industries without chemical stoichiometry.
Explanation:
Hopefully this helps :D
Sorry you had to wait so long :(

reactive and is very similar to the other elements in its
group. Your friend's element is most likely which of these?
A. A transition metal
B. A noble gas
C. A halogen
D. An alkali metal
An element that is commonly found in household materials, malleable, and a good conductor of heat and electricity. They say it is not very reactive and is very similar to the other elements in its group as an alkali metal.
What is an alkali metal ?All the elements listed in column 1A of the periodic table—hydrogen, lithium, sodium, potassium, rubidium, cesium, and francium—are classified as alkali metals. The fact that all of these metals contain one electron in their outermost layer of electrons binds them together.
The production of paper, detergents, and soap all need sodium hydroxide. In addition to being used as the electrolyte in alkaline, Ni-Cd, and Ni-MH batteries, potassium hydroxide is also used by farmers to make acidic soil more alkaline so that plants would grow better in it.
Vinegar, hydrochloric acid, and sulfuric acid are a few examples of the H = ion-containing compounds referred to as acids. Alkalis are a class of substances that feel soapy and contain the OH = ion.
Thus, option D is correct.

What is the formula of a compound that has [1 mol Fe], [1 mol Ti], and [3 mol O]
Answer: [tex]FeTiO_3[/tex]
Explanation:
Molecular formula is the chemical formula which depicts the actual number of atoms of each element present in the compound.
Empirical formula is the simplest chemical formula which depicts the whole number of atoms of each element present in the compound.
The molecular formula for a compound that has [1 mol Fe], [1 mol Ti], and [3 mol O] will be [tex]FeTiO_3[/tex]

what are buffers and why are they important
Explanation:
A buffer is a solution that can resist pH change upon the addition of an acidic or basic components. It is able to neutralize small amounts of added acid or base,thus maintaining the pH of the solution relatively stable.This is important for processes and/or reactions which require specific and stable pH ranges.
