1.Explore two more isotopes and how it is useful in our day to day life.

Chemistry
1 answer:
Daniel [21]3 years ago
6 0

Answer: Isotopes are useful in particular scientific fields. Theoretical astrophysicists point out that several new particles lead to new knowledge.

Explanation:

  • When science reached the fact that chemical elements exist as a set of many different isotopes, it was the cornerstone in discovering the composition of atoms, but also the formation of modern knowledge about the understanding of chemical elements. The practical significance of the discovery above has importance in physics and physical and analytical chemistry. Also, thanks to isotopes, some diagnostic methods have been developed in specific sciences such as geology and archeology. By determining certain radioactive isotopes by means using these two sciences, it is possible to decide on the age of the individual samples.
  • Theoretical physics is a viral branch of science today. This is a relatively young scientific discipline, and one of the greatest minds in the history of Stephen Hawking belonged to this discipline. The development and study of the atomic structure are significant for this scientific discipline. Some scientists point out that a large number of particles will be experimentally discovered in the future, as the atom has been found. It will undoubtedly cause new knowledge and reach for humanity. Thus, throughout history, the development of experimental physics has revealed a large number of particles that, in addition to protons, neutrons, and electrons, are contained in atoms.

9) All elements can be sorted into 3 simple groups:
serious [3.7K]

Answer: B) metals, non-metals, metalloids

An example of a metal is iron. A non-metal example is oxygen, which is a gas at STP (standard temperature and pressure).

A metalloid is a bit of a mix between a metal and non-metal element. It's sorta like an element that has both properties of metals and non-metals, or it's in a murky gray area. An example of a metalloid would be silicon.

Need help asap!
Scilla [17]

Answer: 1.  C. polar covalent: electrons shared between silicon and sulfur but attracted more to the sulfur

2. B)  NH_3

3. B) Fluorine

Explanation:

1. A polar covalent bond is defined as the bond which is formed when there is a difference of electronegativities between the atoms.

Electronegativity difference = electronegativity of sulphur- electronegativity of silicon = 2.5 -1.8 = 0.7

Thus as electronegativity difference is less than 1.7 , the cond is polar covalent and as electronegativity of sulphur is more , the electrons will be more towards sulphur.

2. A molecular compound is usually composed of two or more nonmetal elements. Example: NH_3

Ionic compound is formed by the transfer of electrons from metals to non metals. Example: Mg_3N_2 , AlCl_3 and LiBr

3.  For formation of a neutral ionic compound, the charges on cation and anion must be balanced. The cation is formed by loss of electrons by metals and anions are formed by gain of electrons by non metals.

Here K is having an oxidation state of +1 and as the compound formed is KZ, the oxidation state of non metallic element Z should be -1. Thus the element Z is flourine which exists as diatomic gas F_2
