One atom of silicon is perfectly combined with the \boxed{{\text{two atoms of oxygen}}}  and forms silicon dioxide.

Further explanation:

Law of multiple proportions:

This law states that the molecule is a particle that is made up of two or more element. The elements are always combined in a ratio of fixed whole number.

Silicon has electron configuration \left[{{\text{Ne}}}\right]3{s^2}3{p^2}  so it can form 4 covalent bonds with other atoms.

One atom of silicon is combined with hydrogen in 1:4 ratio and form {\text{Si}}{{\text{H}}_4} . This compound is known as silane. Thus silicon is not able to combine with three hydrogen atoms.

One atom of silicon is combined with calcium as calcium silicate \left({{\text{C}}{{\text{a}}_{\text{2}}}{\text{Si}}{{\text{O}}_{\text{4}}}}\right)   and Calcium silicon \left({{\text{Ca}}{{\text{H}}_{\text{4}}}{\text{Si}}}\right) . Therefore, silicon would not be able to combine with 4 calcium simultaneously.

One atom of silicon is combined with oxygen in 1:2 ratio and form {\text{Si}}{{\text{O}}_2} . This compound is known as silicon dioxide. Thus silicon can combine with two oxygen atoms.

One atom of silicon is combined with chlorine in 1:4 ratio and form {\text{SiC}}{{\text{l}}_4} . This compound is known as silicon tetrachloride. Thus silicon is not able to combine with one chlorine.

Give the number of protons and the number of neutrons in the nucleus of each ofthe following isotopes: (a) Aluminum-25 (b) Techn
NeTakaya

Answer:(a)Aluminium-Al has 12 protons and 13neutrons (b) Technetium-Tc has 43 protons and 52neutrons (c) Tin-Sn has 50protons and 70 neutrons (d) Mercury - Hg has 80protons and 120neutrons

Explanation:

All elements on the periodic table are are arranged in terms of atomic number.

For a neutral atom( uncharged atom) , atomic number is the same as proton number. And the sum of number of proton and number of neutrons gives mass number.

Isotopes exist as a result of difference in mass number of atoms but the same atomic number, which implies isotopes of an element always have the same number of protons but different neutron numbers.

(a) Aluminum-25 has a mass number of 25 with atomic number of 12.

Since its a neutral atom, number of protons is 12 while neutron number can be deduced as,

Mass number = neutron number+ proton number

Neutron numbers= mass number - proton number

Neutron number= 25-12=13neutrons

(b) Technetium -95 has a mass number of 95 with atomic number of 43.

Since its a neutral atom, number of protons is 12 while neutron number can be deduced as,

Mass number = neutron number+ proton number

Neutron numbers= mass number - proton number

Neutron number= 95-43=52neutrons

(c) Tin-120 has a mass number of 120 with atomic number of 50

Since its a neutral atom, number of protons is 50 while neutron number can be deduced as,

Mass number = neutron number+ proton number

Neutron numbers= mass number - proton number

Neutron number= 120-50=70neutrons

(d) Mecury-200 has a mass number of 200 with atomic number of 80.

Since its a neutral atom, number of protons is 80 while neutron number can be deduced as,

Mass number = neutron number+ proton number

Neutron numbers= mass number - proton number

Neutron number= 200-80=120neutrons
