Answer: 2.

Explanation:

1) The number of bonds that an atom is willing to form may be predicted in terms of the octet rule.

2) Atomic number of oxygen is 8, which implies that the atom has 8 electrons.

3) The electron configuration of oxygen is 1s² 2s² 2p⁴.

4) So, oxygen has 6 electrons in its valence shell.

5) The octet rule states that any atom will try to reach the configuration of the closest noble gas by "gaiing" or "giving" the electrons to have the 8 electrons in the outer shell.

6) Then oxygen will be willing to share two electrons with other atoms to complete, along with its own 6 electrons, the 8 electrons, which leads to the configuration of the noble gas Ne.

7) Each electron shared contributes to the formation of a bond. That is why by sharing two electrons, oxygen will form two covalent bonds.

Write the atomic number, atomic mass, number of protons, electrons and neutrons for the first five elements

stepladder [879]

Answer:

The first five elements of the periodic table are:- hydrogen, helium, lithium, beryllium, boron

Explanation:

atomic number- it is represented by the letter Z. It is basically the total number of protons present in each atom's nucleus of that element.

atomic mass- is the mass of a single atom present in the element.

electrons and protons- they are negatively and positively charged particles found in the nucleus of the atom respectively.

neutrons- they have no or zero charge and weigh more than protons.

hydrogen (H)- 1 | 1.008 | 1 | 1 | 0

helium (He) - 2 | 4.0026 | 2 | 2 | 2

Lithium (Li) - 3 | 6.94 | 3 | 3 | 4

beryllium (Be) - 4 | 9.0122 | 4 | 4 | 5

Boron ( B) - 5 | 10.81 | 5 | 5 | 6

1. The following are statements about flames some of them are true while others are

hoa [83]

Answer:

i)The carbon particles are formed when the gas is not completely burnt(True)

ii)A solid or liquid must be change to gaseous state in order to make flame(TRUE)

iii)A non- luminous Bunsen flame produces has three visible regions(FALSE)

iv)The luminous Bunsen flame produces less soot than the non- luminous flame(FALSE)

v)A yellow Bunsen flame is obtained when the air holes are opened(FALSE)

vi)The luminous Bunsen flame is hotter than a non- luminous Bunsen flame(FALSE)

vii)Bunsen burner uses kerosene as a source of heat(FALSE)

Explanation:

i)When the incomplete combustion ,then CO(carbon monoxide) and C(carbon) are produced. The unburnt carbon get deposited as Soot.

In complete combustion CO2(carbon dioxide) is produced.

ii)Fire, is the mixture of hot gases.Flame are result of chemical reaction between oxygen and fuel(e.g butane ,wood).Flame contain,carbon dioxide , heat ,light,steam.

iii)There are total three regions of flame in which the outer most region is the non-luminous .The non-luminous part is blue(one visible region) and does not emit-light.

iv) Luminous Bunsen flame produces more soot than the non- luminous flame because luminous flame contain more unburnt particles as compare to non-luminous.

luminous part has less oxygen available for complete combustion of fuel

v)When the air hole is open it means excess oxygen is supplied to the fuel.

In this case clean and luminous flame is produced.When air hole is close yellow flame is produced.

vi)Non-luminous part of flame is more hot because of complete combustion due to proper availability of oxygen. Sometime the particle of non-luminous flame get ionize also.

vii).The bunsen burner uses Natural gas(methane) or LPG(propane and butane)as sources of heat because these are easily burnt not kerosene.
