An atom's Lewis dot structure has three dots. Which of the following elements could it be, and why? (4 points)

Group of answer choices

Aluminum, because it is in group 13 and has three valence electrons.

Lithium, because it is a group 1 element with three total electrons.

Magnesium, because it is in period 3 and has three valence electrons.

Potassium, because it is an alkali metal and has three inner shell electrons.

Answers

Answer : The correct option is, Magnesium because it is a group 2 element with two valence electrons.

Explanation :

Element = Calcium

Atomic number = 20

Electronic configuration of Ca =  

Number of valence electrons in Ca = 2

The number of inner shell electrons in Ca = 18

This option is wrong because lewis-dot structure shows only valence electrons not inner shell electrons.

Element = Carbon

Atomic number = 6

Electronic configuration of C =  

Number of valence electrons in C = 4

This option is wrong because only outermost p-sublevel electrons are not showing in lewis-dot structure.

Element = Lithium

Atomic number = 3

Electronic configuration of Li =  

Number of valence electrons in Li = 1

This option is wrong because it has only 1 electron in outermost shell.

Element = Magnesium

Atomic number = 12

Electronic configuration of Ma =  

Number of valence electrons in Ma = 3

This option is correct.

Lewis-dot structure : It is defined as the structure in which valence electrons of the atom is shown as dots.

ANOTHER EXPLANATION:

Answer: C. Magnesium, because it is a group 2 element with two valence electrons.

An atom's Lewis dot structure has two dots. Which of the following elements could it be, and why?

A. Calcium, because it is an alkaline earth metal with two inner shell electrons.

B. Carbon, because it has two electrons in its outermost p sublevel.

C. Lithium, because it is a group 1 element with two bonding electrons.

D. Magnesium, because it is a group 2 element with two valence electrons.

Explanation:

If you were to look at the periodic table magnesium would be in group 2. Since magnesium is in group 2 therefore it will have two valence electrons. Calcium is another possible answer because it is also in group two, but for this quiz it is incorrect. Lithium is incorrect because it is in group 1 and therefore it would only have 1 valence electron. Carbon is also incorrect because it is in group 14 so it would have 4 valence electrons. Hope this helps and makes sense.

Good Luck!!

The Lewis dot structure of an atom has three dots. With three valence electrons and belonging to group 13, which of the following elements may it be?

Are the elements of group 13 metals?

The semi-metal boron (B) and the metals aluminum (Al), gallium (Ga), indium (In), and thallium (In) are all members of the boron family (Tl). The periodic table's fifth element, boron (Z=5), is found in Group 13. It is categorized as a metalloid because of its characteristics, which combine those of metals and nonmetals.

What traits does group 13 exhibit?

The Periodic Table of Elements places these elements in Group 13 (XIII) of the p block. Metallic elements include thallium, gallium, indium, and aluminum. In their outermost shells, they each have three electrons shell with the valence electron configuration ns2np1 (one electron in the p orbital and a complete s orbital).

Where does the energy of a hurricane come from? (1 point)
O the Sun
O strong winds
O Earth's spin
O Earth's moon

Answers

Answer:

strong winds come from the energy of a hurricane

The energy of a hurricane come from strong wind. The Taino Native American term hurricane, which translates to "bad spirit of the wind," is where the word hurricane originates.

What is hurricane ?

A tropical storm that has sustained winds of 74 mph or greater is referred regarded as a hurricane. A storm's eye typically measures 20 to 30 miles in width and can reach distances of 400 miles. Storms can be dangerous because of their torrential downpours, strong gusts, and storm surges.

When warm, humid air begins to rise over water, hurricanes emerge. Cooler air replaces the rising air. Large clouds and thunderstorms continue to grow as a result of this process. Thanks to the earth's Coriolis Effect, these thunderstorms are still expanding and starting to rotate.

Thus, option B is correct.
