Answer:

The correct option is B) One atom of sodium and one atom of fluorine.

Explanation:

An ionic bond is produced between metallic and non-metallic atoms, where electrons are completely transferred from one atom to another. During this process, one atom loses electrons and another one gains them, forming ions. Usually, the metal gives up its electrons forming a cation to the nonmetal element, which forms an anion. In this way, the octet rule is fulfilled, which establishes that the atoms of the elements bind each other in the attempt to complete their valence layer, leaving the atom stable with 8 electrons in its last layer.

Given this, the correct option is option B). Sodium is a metal forming the cation and fluorine is a nonmetal, then it will form the anion.

Answer this please (its due tommarow)
Darina [25.2K]

Answer:

The water cycle consists of 3 major processes.

**Evaporation

**Condensation.

**Precipitation.

01)Evaporation, : Evaporation is the process of a liquid s surface changing into a gas.

02)Condensation: Condensation is the process of gas changing to a liquid.

03)Precipitation: In the water cycle, water vapour in the atmosphere condenses and become liquid.

WHAT IS WATER CYCLE DO?

## The water cycle shows the continues movement of water within the Earth and atmosphere.

** Liquid Water--------------- Water vapour. ( Evaporate)

*** Condenses-------- To Clouds

( Turn)

, and precipitations back to the form of rain and snow. Water do transform around the atmosphere.

Tip::: who made the water cycle???

The sun heat.

Which diagram shows a voltaic cell?
boyakko [2]
Since you have not included the figures with the diagrams to select the right answer, I am going to explain the main differences that lead you to differentiate electrochemical cells.

There are four important terms needed to identify the electrochemical cells: electrolysis, electrochemical cells, electrolitc cells and voltaic cells.

1) Electrochemical cell: is a device that uses a chemical reaction (redox reaction) to produce electricity or that uses electricity to product a chemical reaction.

2) Electrolysis: is the production of a chemical reaction using electricity.

3) Electroltic cell: is one of the two types of electrochemical cell. It is that in which electricity is used  to produce the chemical reaction, i.e. where electrolysis happens. For example, the decomposition of sodium chloride brines is done in an electrolitic cell.

4) Galvanic cell: is the other type of electrochemical cell. It is that in which chemical reactions (redox reactions) produce electricity. The battery of the car is an example of a galvanic cell.

Here you are asked to identify which diagram shows a voltaic cell.So, you need to lool at:

- a redox reaction is happening

- this redox reaction is producing electricity (not that the electricity is producing the reaction)

Remember that a redox reaction is where some atoms are being reduced (gaining electros) and others are being oxidized (losing electrons).

Tha information will let you to choose the righ diagram.

Which of the following elements has the lowest electron affinity?
RUDIKE [14]

Answer:

k

Explanation:

electron affinity (EA) depends on various factors like effective nuclear charge (enc) , size of the atom, ellipticity of sub-shell (ep) , nature of configuration.

more is the enc more will be the EA

more is the size less will be the EA

more valance shell ellipticity (closer to the nuclei) more will the EA ( all given element posses P orbital in the valance shell)
