What experimental evidence led Rutherford to conclude the following: (a) The nucleus of the atom contains most of the atomic mas

s. The nucleus of the atom contains most of the mass since only a collision with a very dense, massive object would cause an alpha particle to be the source. (b) The nucleus of the atom is positively charged. The positive alpha particles their initial flight indicating that the nucleus of the atom is also positively charged. (c) The atom consists of mostly empty space. Most alpha particles pass through the gold foil leading to the conclusion that the atom is mostly empty space.

Answer:

See Explanation

Explanation:

The experiment of Ernest Rutherford involved the bombardment of a thin gold foil with alpha particles from a radioactive source. A zinc sulphide screen was used to follow the movement of the alpha particles.

It was discovered that most of the alpha particles  followed a  straight path through the gold foil. Some of them were scattered through large angles and few were even scattered in the backward direction.

Since alpha particles were heavier than electrons, they must have been deflected by very strong forces.

These experimental evidences led to the conclusions stated in the question.

Rutherford, geiger, and marsden’s experiment demonstrated that the volume of the nucleus is roughly what fraction of the volume
trasher [3.6K]
Rutherford, Geiger and Marsden's experiment proved that every atom has a nucleus and that this nucleus is of positive charge and contains the most of the mass of the atom. 0.005% of the volume occupied by the electrons is the volume of the nucleus.

Write the formula and calculate the molecular mass of
Reika [66]

The molecular formula is the sum of the atomic masses of all atoms in the molecule.

The formula of Soda Ash:

Na₂CO₃ is also known as Sodium Carbonate.

The molecular mass of Soda Ash is

(2×Na)+(1×C)+(3×O)=106g/mol

The formula of Baking Soda:

NaHCO₃ is also known as Sodium bicarbonate.

The molecular mass of Baking Soda is

(1×Na)+(1×H)+(1×C)+(3×O)=84g/mol

The formula of Lime Stone:

CaCO₃ is also known as Calcium carbonate.

The molecular mass of Lime Stone:

(1×Ca)+(1×H)+(1×C)+(3×O)=100g/mol

The formula of Ethanol:

C₂H₅OH is the formula of ethanol.

The molecular mass of Ethanol:

(2×C)+(6×H)+(1×O)=46g/mol

The formula of Common Salt:

NaCl is also known as Sodium chloride.

The molecular mass of Common Salt:

(1×Na)+(1×Cl)=58.5g/mol

What kind of bond will form between the atoms?
Karo-lina-s [1.5K]

ionic bond:

Bond formed when an atom donates its electron and other atom receives those electrons.

polar covalent:

Bond formed by equal sharing of electrons between both the atoms and there is an electronegativity difference between the two atoms.

Nonpolar covalent:

Bond formed by equal sharing of electrons between both the atoms and there is no electronegativity difference between the two atoms.

Metallic:

Formed between two metals.

So the bond between :

Phosphorus and chlorine-polar covalent bond as it is formed by equal sharing of electrons between both the atoms and there is an electronegativity difference between the two atoms.

Potassium and oxygen -ionic bond as here potassium donates its electron and oxygen receives those electrons

Fluorine and fluorine -Non polar covalent bond as formed by equal sharing of electrons between both the atoms and there is no electronegativity difference between the two atoms.

Copper and aluminum-metallic bond as Formed between two metals.

Carbon and fluorine -polar covalent bond as it is formed by equal sharing of electrons between both the atoms and there is an electronegativity difference between the two atoms.

Carbon and hydrogen --Non polar covalent bond as formed by equal sharing of electrons between both the atoms and there is no electronegativity difference between the two atoms.

Aluminum and oxygen--ionic bond as here aluminum donates its electron and oxygen receives those electrons

Silver and copper --metallic bond as Formed between two metals.
