Metallic Bond is basically a electrostatic force of attraction between the metal ions which are arranged in a lattice(Lattice is a regular repeating pattern) and the free electrons floating around the metal ions.
1- Metals are good conductors of heat and electricity
2- Metals are ductile
3- Metals are malleable
4- Metals are solid at room temperature
5- Metals Possess Metallic luster

B. The first electron shell holds 8 electrons.
C. All atoms contain two electron shells.
An electron's exact position cannot be pinpointed is the features of the electron cloud model of an atom. Therefore, option A is correct.
In 1926, Werner Heisenberg and ErwinSchrödinger created the electron cloud model. The model is a tool for aiding in the visualization of the electrons' most likely location within an atom.
The electron cloud model is another name for the contemporary theory. This is due to the fact that each orbital surrounding an atom's nucleus resembles a fuzzily arranged cloud.
According to definition, an electron cloud is the area around the nucleus of an atom where electrons are most likely to be found.
Thus, option A is correct.

Answer: a
Explanation:
Water has a higher boiling point than expected because D. of the strong attraction between polar water molecules.
The higher boiling point of water is due to the strong attraction between polar water molecules. Water molecules are polar because of the unequal distribution of electron density between the oxygen and hydrogen atoms, resulting in a slightly positive charge on the hydrogen atoms and a slightly negative charge on the oxygen atom.
Thus, these partial charges create attractive forces called hydrogen bonds between neighboring water molecules, making it difficult to separate the molecules and requiring more heat energy to overcome these attractive forces and reach the boiling point.

I hope that's help !
It dissolves.
It increases the pH of the solution.
It releases hydroxide ions.
Answer: Option (a) is the correct answer.
Explanation:
An acid-base indicator is an indicator which changes color according to the pH of solution in which it is placed.
For example, phenolphthalein is an acid-base indicator.
Thus, we can conclude that out of the given options, an acid–base indicator react by changing color when placed in an acidic solution, is the correct option.
