Answer:
Silicon and oxygen
Explanation:
All silicate minerals must contain silicon and oxygen even though the name might mislead one into thinking it is only just silicon. Actually the suffix -ate in chemistry is used when an element is combined with oxygen. Which is why the carbonate ion has carbon and oxygen, the nitrate ion has nitrogen and oxygenThis repeats itself in the sulphate ion, phosphate ion, chromate ion, manganate ion etc.
Answer: Protons inside the nucleus of an atom are held together despite having the same positive charge because of the strong nuclear force, also known as the strong nuclear interaction or simply the strong force. The strong force is one of the fundamental forces in nature, along with gravity, electromagnetism, and the weak nuclear force. It is responsible for binding protons and neutrons (collectively known as nucleons) together in the nucleus of an atom.
Explanation: The strong force is an extremely powerful force at very short distances, acting over a range of about 1 femtometer (10^-15 meters). This force is much stronger than the electrostatic repulsion between protons due to their positive charges. So, even though protons have the same positive charge and would naturally repel each other due to the electromagnetic force, the strong nuclear force overcomes this repulsion and binds them together within the nucleus, keeping the nucleus stable.
Protons inside the nucleus of an atom are held together by the nuclear force, also known as the strong nuclear force. This force is strong enough to override the repulsive electromagnetic force between protons.
Protons inside the nucleus of an atom, despite having the same positive charge and thus naturally repelling each other, are held together fundamentally due to a force called the nuclear force, sometimes referred to as the strong nuclear force or strong interaction.
This is one of the four basic forces of nature, the others being gravity, electromagnetic force, and the weak nuclear force. The nuclear force is so strong that it overrides the repulsive electromagnetic force between protons thereby holding the protons together inside the nucleus.

Molecular compounds can not conduct electricity because they do not break up into ions. Therefore, option (A) is correct.
Molecular compounds can be characterized as those compounds where the atoms are connected by covalent bonds. The covalent bond is generally created by the mutual sharing of electrons by the atoms. In molecular compounds, intermolecular forces are responsible for bond formation.
The melting point of the molecular compound is low as compared to the ionic compound as the energy required to break bonds is less compared to the ionic bond between ions in the crystalline ionic compound.
Molecular compounds are generally by the reaction between non-metals. Molecular compounds are also known as covalent compounds. The ionic and molecular compound differ from each in their physical properties,
The molecular compounds do not conduct electricity as they do not bark into ions. Therefore they can behave as insulators while ionic compounds conduct electricity.

(1) Sodium has a melting point of 371 K.
(2) Sodium has a molar mass of 23 grams.
(3) Sodium can conduct electricity in the liquid
phase.
(4) Sodium can combine with chlorine to produce
a salt.
Answer;
(4) Sodium can combine with chlorine to producea salt.
Explanation;
Sodium is an alkali metal (group 1 ) in the periodic table. It is a soft metal, reactive and with a low melting point. It has an atomic weight of 23 grams.
Sodium is a good conductor of electricity due to the presence of delocalized electrons in its metallic structure. It reacts vigorously with water to produce sodium hydroxide and hydrogen.
-When exposed to air, metallic sodium recently cut looses its silvery appearance and acquires an opaque grey color due to the formation of a sodium oxide coating.
