Which pair of elements will most likely exhibit similar chemical properties?

Which pair of elements will most likely exhibit similar chemical properties?

Elements that are in the same group of the periodic table are most likely to exhibit similar chemical and physical properties. We therefore expect that Ca and Mg should be most alike because they are in the same group (group 2A, the alkaline earth metals). Locate Na (sodium) and Br (bromine) on the periodic table.

What are similar chemical properties?

Two different elements have similar chemical properties when they have the same number of valence electrons in their outermost energy level. Elements in the same column of the Periodic Table have similar chemical properties.

What are 3 elements that have similar properties?

Answer:The elements in the first column of the Periodic Table (other than hydrogen) are known as Group 1A metals, or alkali metals. When you compare the chemical properties of these elements (lithium, sodium, potassium, rubidium, cesium, and francium), what you’ll notice is that they are all remarkably similar.

What two elements have similar properties?

Which two elements have the most similar chemical properties?

  • Finding what elements have the most similar chemical properties is easy.
  • Let’s try an example.
  • Which two elements have the most similar chemical properties?
  • (1) beryllium and magnesium.

Which element is very unreactive?

Group 8A (or VIIIA) of the periodic table are the noble gases or inert gases: helium (He), neon (Ne), argon (Ar), krypton (Kr), xenon (Xe), and radon (Rn). The name comes from the fact that these elements are virtually unreactive towards other elements or compounds.

Why is Group 8 so unreactive?

Group 8 elements are also known as zero group elements as they have zero valency. The reason for them being inert is that all of their shells are completely filled. Inert gases have ns2 np6 configuration which shows that they have 8 electrons in their valence shell.

Why is this element unreactive?

When elements react, their atoms complete their outer shells by losing, gaining, or sharing electrons . Atoms of group 0 elements already have stable arrangements of electrons. This means that they have no tendency to lose, gain, or share electrons. This is why the noble gases are unreactive.

Why is Xenon so unreactive?

Xenon is one of the noble gases and it is so unreactive because of the number of electrons that are present in its outer shell. Since the outer shells of the noble gases are complete, they lack the tendency of the gain, lose, and sharing of the electrons.

Why is Krypton so unreactive?

The atoms of noble gases already have complete outer shells, so they have no tendency to lose, gain, or share electrons. This is why the noble gases are inert and do not take part in chemical reactions.

Is Xenon highly reactive?

Xenon is one of the inert or noble gases and is odorless, colorless, tasteless and chemically non-reactive. While not toxic on its own, its compounds are strong oxidizing agents that are highly toxic.

Why is Xenon the most reactive noble gas?

Noble gases are generally unreactive, but XENON compounds are reactive. It is so because the electrons in Xe are much less strongly bound to the atom , owning to it’s large size.

Which is the least reactive noble gas?

Argon

Is Xenon harmful to humans?

Health effects of xenon Inhalation: This gas is inert and is classified as a simple asphyxiant. Inhalation in excessive concentrations can result in dizziness, nausea, vomiting, loss of consciousness, and death. Death may result from errors in judgment, confusion, or loss of consciousness which prevent self-rescue.

Which is the most abundant rare gas in the atmosphere?

Which noble gas is most abundant in the atmosphere?

Which noble gas is most abundant in nature?

Which noble gas is most abundant in atmosphere dry air?

argon

What is the rarest gas on Earth?

Krypton

Which noble gas has the most developed chemistry?

The chemistry of the heavier noble gases, krypton and xenon, are well established.

What are the 7 noble gases?

Noble gas, any of the seven chemical elements that make up Group 18 (VIIIa) of the periodic table. The elements are helium (He), neon (Ne), argon (Ar), krypton (Kr), xenon (Xe), radon (Rn), and oganesson (Og).

Why are Group 18 called noble gases?

The group 18 elements are helium (He), neon (Ne), argon (Ar), krypton (Kr), xenon (Xe), and radon (Rn). These elements are non-reactive and are called noble gases as they have their outermost orbit complete. Due to stable electronic configuration they hardly react with other elements.

Is inert gas and noble gas the same?

Unlike noble gases, an inert gas is not necessarily elemental and is often a compound gas. This is a tendency, not a rule, as noble gases and other “inert” gases can react to form compounds. The group 18 elements include helium, neon, argon, krypton, xenon and radon. They are referred to as noble gases or inert gases.

Why is it called a noble gas?

The noble gases, in order of their density, are helium, neon, argon, krypton, xenon and radon. They are called noble gases because they are so majestic that, in general, they don’t react with anything. For this reason they are also known as inert gases.

Which gas does not exist in air?

– Therefore Radium is not a noble gas and it is not present in the atmosphere. So, the correct answer is “Option B”. Note: Radium is not available in nature because it is prepared from a radioactive decay of other radioactive elements.

Why zinc is not a noble gas?

A valence subshell is one which can react to form a bond. So the definition of valence orbitals doesn’t depend on their quantum numbers, but on the energy required to fill them. That’s why zinc is not a noble gas – the 4p orbitals count as valence (reactive) orbitals for zinc even while the 4d don’t.

Why don t the noble gases react?

The full valence electron shells of these atoms make noble gases extremely stable and unlikely to form chemical bonds because they have little tendency to gain or lose electrons. Although noble gases do not normally react with other elements to form compounds, there are some exceptions.
