Identify the main purpose of the Periodic Table. *
saw5 [17]

The periodic table is one of the most important tools in the history of chemistry. It describes the atomic properties of every known chemical element in a concise format, including the atomic number, atomic mass and relationships between the elements. Elements with similar chemical properties are arranged in columns in the periodic table.

The table thus is a quick reference as to what elements may behave the same chemically or which may have similar weights or atomic structures.

Is this an example of physical or chemical weathering?<br><br><br> chemical<br><br><br> physical
skelet666 [1.2K]

Answer:

Physical

Explanation:

because the erosion of the canyon did not change any of the chemical attributes of the rock it only changed the appearance. it may have changed the color which is an example of chemical properties but in this case, it is physical. But in other cases, you would refer to this type of weathering as mechanical weathering.

The 488 nm laser is shine on a lithium metal whose work function is 2.9 eV will you be able to see any photoelectrons? if yes wh
nalin [4]

Answer:

There will not be any ejection of photoelectrons

Explanation:

Energy of the photon= hc/λ

Where;

h= Plank's constant

c= speed of light

λ= wavelength of the incident photon

E= 6.6×10^-34 × 3 ×10^8/488 × 10^-9

E= 4.1 ×10^-19 J

Work function of the metal (Wo)= 2.9 eV × 1.6 × 10^-19 = 4.64 × 10^-19 J

There can only be ejected photoelectrons when E>Wo but in this case, E<Wo hence there will not be any ejection of photoelectrons.

Find the elements sodium, oxygen, and phosphorus on the periodic table. Describe the monoatomic ions each would form. Then, give
miskamm [114]
Sodium would form Na+

Oxygen would form O-2

Phosphorus would form -3 or +5

Sodium and oxygen would combine to form ionic bonds because one is a metal and the other is non-metal, while Phosporus and oxygen would combine to form covalent bonds because they are both non-metals.
