What is called compound?

  • In chemistry, a compound is a substance made up of two or more different chemical elements combined in a fixed ratio.
  • When the elements come together, they react with each other and form chemical bonds that are difficult to break.
  • These bonds form as a result of sharing or exchanging electrons between atoms.

a) Mg(OH)2 or Ni(OH)2.

Mg(OH)2 1.8×10–11

Ni(OH)2 2.0×10–15

Clearly, Ksp value for Mg(OH)2 is higher , meaning it is MUCH MORE SOLBULE than Nickel

therefore, choose Mg(OH)2.

b)

PbS 3×10–28

CuS 6×10–37

Clearly, PbS is much more soluble than CuS

since Ksp is higher .

c)

Ag2SO4 1.4×10–5

MgF2 3.7×10–8

Clearly, Ag2SO4 has higher Ksp, so it is much more soluble.

Atoms have a tendency to complete their outer energy level. This is known as _____.
Alina [70]

Answer : Option C) The Octet Rule

Explanation : Atoms have a tendency to complete their outer energy level. This is known as Octet Rule.

The octet rule is a chemical rule of thumb which reflects the observation, that atoms of main-group elements tends to combine in such a way that each atom gets eight electrons in its valence shell, which gives it the same electron configuration as that of a noble gas.

In short, the tendency of an atom to fill its valence shell and attain a stable state it acquires or donates the electron is called as octet rule.

The chemical properties of an atom are determined by while bonding is determined by the .
Alenkasestr [34]

The chemical properties of an atom are determined by the number of the electrons while bonding is determined by the arrangement and the valency of the electrons.

<h3>What is an Atom?</h3>

The smallest component of ordinary stuff that makes up a chemical element is an atom.  Atoms that are neutral or ionized make up every solid, liquid, gas, and form of plasma. Atoms are incredibly tiny, measuring typically 100 picometers across. Due to quantum effects, they are so small that it is impossible to predict their behavior with sufficient accuracy using classical physics, as would be the case, for example, if they were tennis balls.

Each atom is made up of a nucleus and one or more electrons that are linked to it. One or more protons and a significant number of neutrons make up the nucleus. Only the most prevalent type of hydrogen is neutron-free. The nucleus of an atom contains more than 99.94% of its mass.
