Magnesium reacts with fluorine to form magnesium fluoride. Which diagram shows the correct arrangement of electrons in the product?
Answers
Answer:
Diagram B shows the correct arrangement of electrons in the product.
Magnesium reacts with fluorine to form magnesium fluoride two electrons of magnesium are transferred to the 2 atoms of fluorine and fluorine is the most electronegative element of the periodic table. Option C is correct.
What is electronegativity?Electronegativity is the tendency or power of an atom to attract the electrons from the metals they are mostly nonmetals and want to complete their octave too.
The most electronegative elements of the periodic table are oxygen, nitrogen, and fluorine, as they are always willing to complete the octave, and fluorine will take electrons from magnesium.
Therefore, Option C is correct if the 2 atoms of fluorine and fluorine are the most electronegative element of the periodic table. Magnesium reacts with fluorine to form magnesium fluoride two electrons of magnesium are transferred.

differentiate between short period and long period
Answers
The question is incomplete. The complete question is as follows:
Differentiate between a short period and long period production functions.
Answer:
Difference between a short period and long period production functions is as follows:
Short period: During this period at least one of the factors of production is available in a fixed quantity. For example: Framers having fixed land for growing crops.
Long period: During this period all the factors of production are variable. So change in any variable can increase the production.

how many atoms are in 2.10 g of K? molar mass of K=39.10g/mole.
Answers
Answer:
The answer is option BExplanation:
To calculate the number of atoms we must first calculate the number of moles
Molar mass = mass / number of moles
number of moles = mass / Molar mass
Molar mass (K) = 39.10mole
mass = 2.10g
number of moles = 2.10/ 39.10
= 0.0537mol
After that we use the formula
N = n × L
where n is the number of moles
N is the number of entities
L is the Avogadro's constant which is
6.02 × 10^23 entities
Number of K atoms is
N = 0.0537 × 6.02 × 10^13
N = 3.23×10^22 atoms of KHope this helps you.

The number of joules needed to raise the temperature of 32 g of water from 12 °C to 54 °C is
The specific heat of water is 4.184 J/g °C.
Answers
Answer: 5,600 J
Explanation:
Joules = mass x specific heat x temperature change
32 x 4.184 x (54 - 12)
= 133.888 x 42
= 5,623.296
(significant figures => 5,600)

For Group 2A metals, which electron is the most difficult to remove? the second the first the third All the electrons are equally difficult to remove.
Answers
Answer:
the third
Explanation:
when you remove the first the nucleur attraction becomes greater pulling the other valence electron closer thus the more you remove the harder it gets because the pull from the nucleus increases.
There are various kind of elements that are present in periodic table. Some elements are harmful, some are radioactive, some are noble gases. Option C is correct option.
What is periodic table?Periodic table is a table in which we find elements with properties like metals, non metals, metalloids and radioactive element arranges in increasing atomic number.
The elements that belongs to Group 2A metals are alkaline earth metals, their electronic configurations is [noble gas ]ns² so, it is easy to remove first electron and then second electron but it is very difficult to remove the third electron because after removing two electron we get noble gas configuration and effective nuclear charge also increases after removal of second electron.
Therefore, the correct option is option C.

What did the photoelectric experiment demonstrate?
A. Light can cause electrons to be released from the surface of a
metal.
B. Light can deposit electrons on a metal surface.
C. Light can make metal atoms move around, producing electricity.
D. Light can heat metal enough to produce electricity.
Answers
Explanation:
When an electromagnetic wave like light hits a material, the electrons gets emitted. The emission of electrons is called photoelectric effect. The emitted electrons are called photoelectrons. In this process the transfer of energy takes place from light to an electron.
Hence, the correct option regarding the photoelectric experiment is (A) " Light can cause electrons to be released from the surface of a metal."

In a chemical reaction, chemical bonds are broken, and new ones are formed.
What is a chemical reaction?Chemical reactions are defined as reactions which occur when a substance combines with another substance to form a new substance.Alternatively, when a substance breaks down or decomposes to give new substances it is also considered to be a chemical reaction.
There are several characteristics of chemical reactions like change in color, change in state , change in odor and change in composition . During chemical reaction there is also formation of precipitate an insoluble mass of substance or even evolution of gases.
There are three types of chemical reactions:
1) inorganic reactions
2)organic reactions
3) biochemical reactions
During chemical reactions atoms are rearranged and changes are accompanied by an energy change as new substances are formed.
