How common is tin?

Tin is relatively rare, making up only about 2 parts per million of the Earth’s crust, according to the U.S. Geologic Survey.

What does tin do for the human body?

Organic tin compounds form when tin binds to carbon. People take tin by mouth for cancer. People apply tin to the skin for bad breath, dental cavities, sensitive teeth, gingivitis, plaque, and hair loss. Tin is used to make plastics, pesticides, paints, wood preservatives, and rodent repellants in manufacturing.

What is the characteristic of tin?

Tin is a soft, malleable, ductile and highly crystalline silvery-white metal. When a bar of tin is bent, a crackling sound known as the “tin cry” can be heard from the twinning of the crystals. Tin melts at low temperatures of about 232 °C (450 °F), the lowest in group 14.

Why is tin so important?

Tin has been used in many ways, and as an element perhaps is best known for its use in tin cans. And this metal is used to prevent corrosion and to produce glass. It is most often found mixed, or alloyed, with other metals. Electro-plating is an important application of tin.

What makes tin unique or special?

Tin (Sn) has an atomic number of fifty, and fifty protons in the nucleus. It is typically a silvery white color and is highly malleable. Interesting Tin Facts: Tin has been in use by ancient civilizations for thousands of years.

Is tin a natural metal?

Tin (Sn), a chemical element belonging to the carbon family, Group 14 (IVa) of the periodic table. It is a soft, silvery white metal with a bluish tinge, known to the ancients in bronze, an alloy with copper. Tin is widely used for plating steel cans used as food containers, in metals used for bearings, and in solder.

Which kind of atoms are the smallest?

Thus, helium is the smallest element, and francium is the largest. From top to bottom in a group, orbitals corresponding to higher values of the principal quantum number (n) are being added, which are on average further away from the nucleus, thus causing the size of the atom to increase.

What is the atomic symbol for silver?

What is the last element in Period 4?

krypton

Which Period 4 element has the most metallic?

Answer Expert Verified. The answer is (4) Sc. The metallic properties has the rule that from left to right, the metallic property is from high to low.

What is the last element?

The last known element has an atomic number 118. The question is whether there is the eight or even others periods. It’s clear that elements from these periods will be extremely unstable.

Why does Period 4 have 18 elements?

This results in the fourth period containing 18 elements due to the additional 10 electrons that are contributed by the d sublevel. The fifth period is similar to the fourth. After the 6 s sublevel fills, the 4 f sublevel with its 14 electrons fills.

How can you justify that 4th period has 18 elements and 6th period has 32 elements?

Hence, in all there are 9(1+3+5) orbitals that can be filled in this period. Since according to Pauli’s exclusion principle, each orbital, at the maximum, can accommodate two electrons. Therefore, 9 orbitals, at the maximum, can have 18 electrons and hence, fourth period has 18 elements.

Why there are 18 elements instead of 32 in 4th period?

Answer. When n = 4, we find that in the orbitals 3d, 4s and 3p which are present in the outermost shells have energies in increasing order — i.e. 3p<4s<3d. So, maximum number of electrons found in the three orbitals is 9X2 = 18. Therefore, 4th period should have 18 elements.
