seraphim [82]

The possible number and location of all subatomic are one of them is electrically neutral, while the other has a stable electronic configuration.

<h3>What are subatomic particles?</h3>

Subatomic particles are those particles that are present inside the atoms. They are electron, neutron, and proton. They are charged particles, protons are positively charged, electrons are negatively charged and neutrons are neutral.

The protons and electrons totally contribute to the atomic mass of the elements.

Thus, the subatomic particles are electrically neutral and stable to electronic configurations.

Which one of the following frequencies of a wave in the air can be heard has an audible sound by the human ear
yulyashka [42]
As a couple of people have pointed out, human hearing ranges from 10 Hz to 10,000 Hz, but as people get older and as they damage their hearing by listening to very loud music, firing guns without ear protection, working in very noisy environments or having other physical damage, that upper end drops off. At 64 yrs old, with a long history of a target shooter before we thought about ear protection, and after many years as a rock and roll disk jockey.<span>

The formulas for ethane, ethene, and ethyne are C 2 H 6 C2H6 , C 2 H 4 C2H4 , and C 2 H 2 C2H2 , respectively. Rank these compou
Anuta_ua [19.1K]

Answer:

Ethane (1.09 A) > Ethene(1.076 A) > Ethyne(1.06 A)

Explanation:

The types of bonds present are:

a) Ethane : single bond

b) Ethene : double bond (one sigma one pi)

c) Ethyne: triple bond (one sigma and two pi bonds)

More the number of bonds lesser the bond length.

Thus the order of bond length of carbon-carbon bond will be:

Ethane (1.09 A) > Ethene(1.076 A) > Ethyne(1.06 A)

An atom of lithium loses an electron. What is the effect of this event? Group of answer choices
Shalnov [3]

Answer:

option C= The atom of lithium becomes positively charged ion

Explanation:

When metals loses the electrons positive ions are formed. The nonmetals accept these electrons and form negative ions. These positive and negative ions attract each other through electrostatic force and form the bond called ionic bond.

Ionic bond:

Ionic bond is formed when oppositely charged ions attract each others i.e negative and positive ions.

We know that a neutral atom consist of equal number of proton and electron, cancel the charge of each other that is equal in magnitude and make the atom neutral or we can say that net charge is zero.

But when the atom lose or gain the electron, imbalance of neutron electron occur so charge will not remain zero and atom is no more to be said neutral.

Example:

Take the example of sodium that can lose one electron and form Na+. This Na+ ion is called cation because it carry positive charge by losing the one electron. This cation now contain eleven proton and ten electron.

Now consider the example of Chlorine atom. It consist of 17 proton and 17 electron. But in order to attain the noble gas configuration or to complete the octet it gain one electron and form anion (Cl-). The chlorine anion consist of 17 proton and 18 electron.

Now consider the compound formed by sodium and chlorine ions. Sodium chloride is an ionic compound. It is formed by the complete transfer of electron from sodium to chlorine atom and form ionic bond. In this ionic compound sodium carry positive charge and chlorine carry negative charge there is attraction between these oppositely charged atoms.

Na+ (cation)

Cl- (anion)

NaCl
