<span>Lithium atoms have one valence electron, where as oxygen atoms have six. Lithium atoms tend to give up their single valence electrons, and oxygen tends to gain two valence electrons from other atoms, like lithium. They do this so they will have filled valence shells. hope this answers your question :)</span>

Lithium is located in group 1 period 2 and oxygen is located in group 16 period 2. These two elements might combine to form a compound because of their oxidation state. Oxygen needs 2 electrons to be stable while lithium is willing to give away 2 electrons to become stable as well.

1-The chemical potential energy of bond A is greater than the chemical potential energy of bond B. Which statement best explains

Tju [1.3M]

It should be noted that bond A has greater energy because C. The atoms in bond A are held more tightly together than the atoms in bond B.

The relationship between the bond energies of nitrogen, iodine, and fluorine gases is that the bond in nitrogen gas is the most difficult to break.

From the information given, the molecule with the greatest bid energy is CH4. The bind energy measures the bond strength that the chemical bond has.

Also, the bond energy of the reactants in reaction 1 is greater than the bond energy of the reactants in reaction 2. Due to this, reaction 1 requires a greater input of energy than reaction 2.

Lastly, the difference in the bond energy of Chlorine and Bromine is that Bromine has more electron levels than chlorine.

Which element has a smaller atomic radius?<br> tungsten (74) or oxygen (8)

Rufina [12.5K]

Answer:

Oxygen

Explanation:

Atomic radius trend

-decreases from left to right

-increases from top to bottom

Tungsten is in period 7, which has a larger atomic radius

Oxygen is in period 2, which is in a lower energy level and is on the right side. Therefore, has a smaller atomic radius.

You witnessed a slide breaking while someone is using a microscope.The silde was not dropped.You are tasked with finding out why

Evgesh-ka [11]

Answer:

See the answer below

Explanation:

<em>The slide could have broken due to the ramming of the objective (especially the high power objectives) into the slide on the stage of the microscope while trying to bring the object on the slide into focus.</em>

It is recommended to <u>start with the lowest objective while trying to focus a slide</u>. Thereafter, the next higher objective can be switched to and the image brought into focus once again. This can be repeated until the desired magnification of the image is reached.

However, <u>at higher objective powers, the coarse adjustment knob should be avoided </u>to avoid the objectives touching/breaking the slide. Instead, the fine adjustment knob should be used.

Hence, the breaking of the slide in the illustration could have been due to the use of the coarse adjustment knob at higher objective powers and the ramming of the objective into the slide.
