Answer:

Electronegativity is the measure of a tendency of an atom to attract the bonding pairs of electrons.

Electronegativity is a measure of how badly an atom wants electrons. The higher an atom's electronegativity, the more greedy it is for electrons, the more it wants to try to steal them from other atom's. This involves a concept called ionic bonding because there are electron givers and electron takers. This has to do with whether an element is a metal or a nonmetal.

Metals are very generous and are willing to let go of or give there electrons away. On the other hand, nonmetals don't give up their electrons.

The rays produced in a cathode tube are
wel

Answer:

Electrons

Explanation:

Cathode rays carry electronic currents through the tube. Electrons were first discovered as the constituents of cathode rays. J.J. Thomson used the cathode ray tube to determine that atoms had small negatively charged particles inside of them, which he called “electrons.”

An element forms an oxide, E₂O₃, and a fluoride, EF₃.(b) How does the group to which E belongs affect the properties of the oxid
xz_007 [3.2K]

Of all the elements, fluorine is the most electronegative and reactive. Fluorine is a diatomic, pale yellow, extremely corrosive, combustible gas with a strong smell. The lightest halogen is it. It produces oxygen and the incredibly corrosive hydrofluoric acid when it combines strongly with water.

<h3>The properties of the oxide and the fluoride?</h3>
  • 1. A mixture of oxygen fluorides with an atomic ratio OF in the range of 1.1-2.04 is generated when fluorine and oxygen mixes are easily circulated through a silent electric discharge.
  • Depending on where you reside in the UK, fluoride is a naturally occurring mineral that is present in water in variable concentrations. It is added to many types of toothpaste and, in some locations, the water supply through a procedure known as fluoridation because it can aid in the prevention of tooth decay.
  • Fluoride stops tooth decay by strengthening the enamel's resistance to acid attack. They also quicken the process of good minerals accumulating in the enamel, further delaying the onset of deterioration. Studies also suggest that fluoride may occasionally be able to stop tooth decay that has already begun.

Is a solution a homogeneous or heterogeneous mixture
Alja [10]

Answer:

Solutions are always homogeneous.

Explanation:

Solution:

Solution are considered homogeneous because in solution the ratio of solute and solvent remain the same throughout the solution. Both solute and solvent are chemically combined and form a new substance.

In solution the particles of solute can not be seen through naked eye.

When the light is passed through the solution it can not scattered.

Example:

When salt is dissolve in water it makes a solution.

The solution also exist in gaseous form. For example oxygen and many other gases dissolved in nitrogen also form a solution.

Mixture:

In mixture substance are physically combined. In mixture every every individual particle retain their properties.

It can be consist of solid, liquid and gas.

Examples:

Sand in water is also a mixture.

Oil in water form mixture.

Which compound has the strongest hydrogen bonding between its molecules? 1. HBr 2. HF 3. HCl 4. HI
Levart [38]
<span>You can compare the strength of the hydrogen bonding by comparing the electronegativities of the other elements. All the four elements, Br, F, Cl and I belong to the same group in the periodic table: group 17 named halogens. Then the kind of bonding they form is similar: polar covalent. You must know the trend of the electronegativities in the periodic table. Electronegativity decrease when you down across a group. Then the electronegativity of F is the higher of the group (indeed, it is the highest of all the 118 elements) . The higher the electronegativity the stronger the attraction that the halogen attracts the electrons and the stronger the hydorgen bonding. Then, the conclusion is that HF has the strongest hydrogen bonding. </span>
