Answer: Element X belongs to the group 16 of the periodic table.
Explanation: We are given that element X combines with iron to form two different compounds having formulas FeX and
As, Iron forms a cation which shows variable oxidation state of +2 and +3. Hence, to form a compound iron needs an anion.
The ratio of iron and Element X is 2 : 3
Hence, the oxidation state of iron = +3 and
Oxidation state of element X = -2
The ratio of Iron and Element X = 1 : 1
Here, the oxidation state of iron =+2
Oxidation state of element X = -2
The elements having the oxidation state -2 belongs to the Group 16.
Answer:
The body with 2.7 has a larger volume
Explanation:
There is a missespelling in the question. The units of density cannot be g, they usually are
In order to answer this question, we need to use the formula of the density of a body:
For body A:
Mass (M) = 5.0 g
Density (D) = 2.7
2.7 = 5g * 1/V
V1 = 5g / (2.7 )
V1 = 1.85
For Body B:
Mass (M) = 5.0 g
Density (D) = 8.4
8.4 = 5g * 1/V
V2 = 5g / (8.4 )
V2 = 0.59
So V1 is bigger than V2
Answer: transferred, atoms , ions
Explanation:
An ionic bond is formed when an element completely transfers its valence electron to another element. The element which donates the electron is known as electropositive element and the element which accepts the electrons is known as electronegative element. This bond is formed between a metal and an non-metal.
For formation of an ionic compound, the metal lose electrons to form positively charged ions called as cations and non metals gain electrons to form negatively charged ions called as anions.
For example:
Sodium atom will loose one electron to gain noble gas configuration and form sodium cation with +1 charge.
Chlorine atom will gain one electron to gain noble gas configuration and form chloride ion with -1 charge.
