Which of the following elements would be expected to resemble germanium Ge most closely in chemical properties?
Which of the following elements would be expected to resemble germanium Ge most closely in chemical properties? arsenic (As) Explanation: Elements with similar chemical propertiesare arranged in the same group or verticalcolumn. Thus Germanium (Ge) would beexpected to have similar properties to silicon(Si).
What element is most similar to germanium?
It is a lustrous, hard-brittle, grayish-white metalloid in the carbon group, chemically similar to its group neighbors silicon and tin. Pure germanium is a semiconductor with an appearance similar to elemental silicon.
What are the chemical properties of germanium?
Germanium is a hard, grayish-white element, has a metallic luster but is brittle like glass. It is classified as a metalloid having the same crystal structure as diamond….Physical Properties.

Which groups of elements should have very similar chemical properties?
Elements within a group have similar chemical properties. Elements that are not in the same group do not have similar chemical properties. This means that lithium (Li), sodium (Na), and potassium (K) should have very similar chemical properties since they are in the same group.
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.
Do N and P have similar properties?
Nitrogen and phosphorous are part of the same ‘family’ on the periodic table, group 15, also called the nitrogen group. Since phosphorus is just below nitrogen, we can expect nitrogen and phosphorus to have some similar properties. They are nonmetals and have similar properties when making compounds.
Which element is most similar to CA?
Its physical and chemical properties are most similar to its heavier homologues strontium and barium. It is the fifth most abundant element in Earth’s crust, and the third most abundant metal, after iron and aluminium….

Do Sr and Ba have similar properties?
Elements that are positioned in the same column (or group) of the periodic table exhibit similar properties. Among the two groups given here, choice (b) Mg, Sr and Ba are alkaline earth elements (part of group IIA) in the periodic table. Other elements of this group are Be, Ca and Ra.
Are boron and oxygen similar?
Boron monoxide (B2O) is another chemical compound of boron and oxygen. Two experimental studies have proposed the existence of diamond-like and graphite-like B2O, as for boron nitride and carbon solids. A later, systematic, experimental study of the boron oxide phase diagram suggests that B2O is unstable.
Does boron bond with oxygen?
In chemistry, an oxoborane is any chemical compound containing a boron atom with a terminal oxygen atom. In these compounds the boron and oxygen form a triple bond prone to cyclotrimerization to boroxines.
Who named boron?
Periodic Table app
| Discovery date | 1808 |
|---|---|
| Discovered by | Louis-Josef Gay-Lussac and Louis-Jacques Thénard in Paris, France, and Humphry Davy in London, UK |
| Origin of the name | The name is derived from the Arabic ‘buraq’, which was the name for borax. |
| Allotropes | α-rhombohedral B, β-rhombohedral B, γ-B, tetragonal boron |
What happens when boron reacts with oxygen?
Chemical properties Boron combines with oxygen in the air to form boron trioxide ( B 2 O 3 ). Boron trioxide forms a thin film on the surface that prevents further reaction with oxygen.
What are 5 physical properties of boron?
The properties of boron are:
- Atomic Symbol: B.
- Atomic Number: 5.
- Element Category: Metalloid.
- Density: 2.08g/cm3.
- Melting Point: 3769 F (2076 C)
- Boiling Point: 7101 F (3927 C)

What elements does boron react with?
Boron reacts vigorously with the halogens fluorine, F2, chlorine, Cl2, bromine, Br2 to to form the trihalides boron(III) fluoride, BF3, boron(III) chloride, BCl3, and boron(III) bromide, BBr3 respectively.
Why is boron not a metal?
Boron atoms form covalent bonds by sharing the valence electrons. Boron is electron deficient and has vacant p-orbitals. It is also the one and only one non-metal group thirteen. So, we can say that the physical and chemical properties of boron are in between metal and nonmetal so it is a metalloid.
Why is it difficult to produce pure boron?
Chemical Properties of Boron Crystalline boron is chemically inert and resistant to attack from boiling hydrofluoric or hydrochloric acid. Industrially, very pure boron can be produced, but this is difficult, because boron tends to form refractory materials that contain small amounts of carbon or other elements.
What happens when boron reacts with chlorine?
Boron react with chlorine to produce boron(III) chloride. This reaction takes place at a temperature of over 400°C.
What is becl3?
Boron trichloride is the inorganic compound with the formula BCl3.
What happens when boron reacts with sodium hydroxide?
Answer: The products formed by the action of boron on NaOH are sodium borate and hydrogen gas. Explanation: The reaction of boron with sodium hydroxide leads to the formation of sodium borate and hydrogen gas.
