When the number of electron and number of protons are equal in the atom then the atom is said to be an electrically neutral atom. The loss of electron will result in the formation of cation and the atom will possess positive charge which is equal to the number of electrons lost whereas the gain of electron will result in the formation of anion and the atom will possess negative charge which is equal to the number of electrons gained.
The electrically neutral atom have 0 charge as the number of protons and electrons are equal.
For electrically neutral atom of hydrogen, the number of electron =1 and the number of proton = 1.
Hence, the charge on an electrically neutral atom of hydrogen is 0.
Its B zero because its neutral meaning that there balance
The mass of acetone is 6.52 g and its density is 0.791 g/mL.
The density of a substance is defined as its mass per unit volume. It is mathematically written as:
Rearranging above equation,
Putting the values,
Therefore, volume of acetone will be 8.24 mL.
C Cl
Formula ____________ Ionic or covalent
Mg Cl
Formula _____________
C Cl is a covalently bonded compound with the formula CCl₄. MgCl is an ionic compound with the formula MgCl₂.
The formation of a chemical bond between two or more atoms, ions or molecules to form a chemicalcompound is known as chemical bonding. The chemical bonding makes sure the atoms are together in the resulting compound.
Chemical bonding is made possible by an attractive force resulting from the overall loss of energy in the resultant molecule compared to its constituents.
Chemical compounds depend on chemical bonding for their stability. There are various kinds of chemical bonds formed. Covalent bonds and ionic bonds are 2 of the most commonly known chemical bonds.
Covalentbonds are formed by the sharing of electrons and an ionicbond is formed by the electrostatic force of attraction between the atoms.
Therefore, in the given examples, C Cl is a covalently bonded compound with the formula CCl₄. MgCl is an ionic compound with the formula MgCl₂.

The bond of the following atoms in C-Cl and Mg-Cl is polar covalent bond in C-Cl and Mg-Cl ionic bond.
Polar covalent bonds are created between two non-metal atoms or molecules that do consist of different electronegativity. and the electronegativity difference that is not equal to zero and the shared pair of electrons forming a bond between will always be towards the high electronegative atom.
An ionic bond the complete sharing or the electron transfer. Ionic bonds basically form or created when the difference in the electronegativity of the two atoms is great or more as compare to covalent bonds form when the electronegativity is same.
Therefore, bond of the following atoms in C-Cl and Mg-Cl is polar covalent bond in C-Cl and Mg-Cl ionic bond.

Answer: balance
Explanation:
Mass is a physical property of a body. It is the measure of resistance of acceleration that a body offers. It is also determined by the strength of gravitational attraction between two or more bodies. The SI unit of mass is the kilogram or gram.
A balance is a device which can be used to measure the accurate mass of the body. The electrical balance has a digital screen which gives the measurements in kilograms or grams in digits.

Both
Answer:
Chemical
Explanation:
(1) CaCO3 (3) MgF2
(2) PCl3 (4) CH2O
Answer: The correct answer is option (A).
Explanation:
Covalent bonds are those bonds in which sharing of an electrons is present in between the two atoms. Generally this type of bonding is found when electro-negativity difference between is very less or zero.
Ionic bonds are those bonds in which complete transfer of an electrons from one atom to another atom is present.Generally this type of bonding is found when electro-negativity difference between two atoms is very large.
Compound contains both ionic and covalent bonds.
