What can be concluded if an ion of an element is smaller than an atom of the same element?(1) The ion is negatively charged because it has fewer electrons than the atom.
(2) The ion is negatively charged because it has more electrons than the atom.
(3) The ion is positively charged because it has fewer electrons than the atom.
(4) The ion is positively charged because it has more electrons than the atom.

Answer 1

Answer: The question is,'what can be concluded if the ion of an element is smaller than the atom of the same element'. The correct option is 'the ion is positively charged because it has fewer electrons than the atom. An atom becomes charged either by donation or accepting electrons. When an atom donate electrons, it becomes positively charged and it has less electrons than its atom. For instance, calcium has 20 electrons, it becomes an ion by donating its two electrovalent electrons, thereby having only 18 electrons left. But when an element accepts electrons, it becomes negatively charged and has more electrons than its atom.

Answer 2

Answer:

The following conclusion can be made if an ion of an element is smaller than an atom of the same element:

$\boxed{\left( 3 \right){\text{ The ion is positively charged because it has fewer electrons than the atom}}{\text{.}}}$

Further explanation:

Ions are the entities with a net electric charge, be it positive or negative. Since positive and negative charges can be present on the ions, ions are of two types-positively charged and negatively charged ions. The ions formed by loss of electrons develop a positive charge and are called cations. But the ions produced by the gain of electrons acquire a negative charge and are called anions.

Since cations are positively charged ions, these have fewer electrons as compared to the corresponding neutral atom. So these ions experience stronger forces of attraction with the atomic nucleus and are smaller in size in size than the parent atom.

Anions are formed by the addition of electrons to the neutral atom. It has more electrons than the parent atom so it feels electron-electron repulsion due to which its size becomes larger than the parent atom.

So cations are smaller than the parent atom of the same element whereas anions are larger than the parent atoms. Therefore if an ion is smaller than the atom, it is positively charged due to the presence of fewer electrons than the parent atom.

Which best describes the trends in electronegativity on the periodic table?

Answers

The correct answer is:

Electronegativity increases up and to the right

Explanation:

Electronegativity, logo χ, is a chemical property that explains the trend of an atom to attract a shared pair of electrons towards itself.As you move from left to right across the periodic table, electronegativity increases, and as you move down the table electronegativity decreases.

Electronegativity is higher on the right side of the periodic table, such as the noble gasses. There electronegativity is around 3.0 and 4.0 while the left side has electronegativity ranging from .7 to 1.0

Considering the law of conservation of mass, if 56 g samples of solid iron (Fe) reacts with 24 g of oxygen (O2), how many grams of Iron Oxide (FeO) are obtained?

Answers

Answer:

62_grams of FeO

Explanation:

Molar mass of Fe = 55.845_g/mol

Molar mass of O2 = 15.999_g/mol

From law of conservation of mass

2 moles of Fe combines with one mole of O2 to form 2 moles of FeO

Number of moles of Fe and O2 present = mass/(molar mass) = 56/55.845~1

and 24/16 = 1.1.5

Therefore

1 part of Fe will react with 0.5 part of one mole of O2

which is 54_g of Fe reacts with 8_g to form 54+8 = 62_grams of FeO

As the temperature of a liquid increases, its vapor pressure(1) decreases
(2) increases
(3) remains the same

Answers

As the temperature of liquid increases, its vapor pressure increases. Therefore, option (2) is correct.

What is vapour pressure?

Vapour pressure can be defined as the pressure exerted by a vapor with its condensed phases in a closed system at a given temperature. The equilibrium vapor pressure is also served as an indicator of the rate of evaporation of a liquid.

A material that has a high vapor pressure at normal temperatures is commonly referred to as a volatile material. The pressure exhibited by the molecules of the gas above a liquid surface is called vapor pressure.

The temperature and the vapor pressure of liquid are directly related to each other. If the temperature of the liquid increases, more gasmolecules have the energy to escape from the surface of the liquid.

Therefore, the vapor pressure increases with an increase in the temperature of the liquid.
