Answer:

Cesium

Explanation:

The atomic radius is the distance between the nucleus and the outermost orbital of an atom. By the atomic radius, it is possible to determine the size of the atom.

The atomic radius is a periodic trend that means that it is a specific pattern in the properties of the chemical elements that are revealed in the periodic table

This property increases as follows (see attached file)

Therefore the element that is lower in the group is the one with the largest radius

In this case, the one located below in the group is cesium, that is, the one with the largest radius

He standard reduction potentials of lithium metal and chlorine gas are as follows: reaction reduction potential (v) li+(aq)+e−→l

AURORKA [14]

2 Li(s) +Cl₂→ 2 Li⁺ (aq) + 2Cl⁻ (aq)

The cell potential of the reaction above is +4.40V

<em><u>calculation</u></em>

Cell potential =∈° red - ∈° oxidation

in reaction above Li is oxidized from oxidation state 0 to +1 therefore the∈° oxid = -3.04

Cl is reduce from oxidation state 0 to -1 therefore the ∈°red = +1.36 V

cell potential is therefore = +1.36 v -- 3.04 = + 4.40 V

The potential energy on a spring is proportional to the square of which of these quantities

erica [24]

The magnitude of the force required to change the length of a spring-like object is directly proportional to the spring constant and the displacement of the spring. Elastic potential energy is directly proportional to the square of the change in length and the spring constant.

In Hawaii, the mongoose was brought to the islands to control the snake population. It thrived, and now the mongoose population

Mila [183]

Answer:

Alien Species

Explanation:

This is known as an alien species threat to biodiversity as there is a newly added species taking over another. Mongooses were intended to control the snake population but it got out of control and is now threatening snake life in Hawaii.
