These diagrams show two atoms of fluorine and an atom of magnesium. which shows the correct steps in the formation of an ionic bond between these atoms? a magnesium atom accepts six electrons from the fluorine atoms → each fluorine atom donates three of the electrons → the magnesium atom becomes a -2 ion → each fluorine atom becomes a +1 ion a magnesium atom donates two electrons to the fluorine atoms → each fluorine atom accepts one of the electrons → the magnesium atom becomes a -2 ion → each fluorine atom becomes a +1 ion a magnesium atom accepts two electrons from the fluorine atoms → each fluorine atom donates one of the electrons → the magnesium atom becomes a -2 ion → each fluorine atom becomes a +1 ion a magnesium atom donates two electrons to the fluorine atoms → each fluorine atom accepts one of the electrons → the magnesium atom becomes a +2 ion → each fluorine atom becomes a -1 ion

the answer is D. A magnesium atom donates two electrons to the fluorine atoms → Each fluorine atom accepts one of the electrons → The magnesium atom becomes a +2 ion → Each fluorine atom becomes a -1 ion

because magnesium only has 2 valence electrons, and it would be easier to lose electrons rather gain.

i just took the test, its right.

The correct steps to the following question will be- A magnesium atom donates two electrons to the fluorine atoms → Each fluorine atom accepts one of the electrons → The magnesium atom becomes a +2 ion → Each fluorine atom becomes a -1 ion.

EXPLANATION:

The electronic configuration of fluorine atom is .

The electronic configuration of magnesium is .

The valence shell of fluorine needs one electron to satisfy inert gas configuration to be stable. On other hand, the magnesium has two electrons in its valence shell. It needs six electrons more to be stable. As it is a electropositive metal, so it will lose two of its electrons to acquire the nearest inert gas configuration i.e neon.

Hence, magnesium will lose two of its valence electrons and becomes a  positively charged cation having +2 charge.

Each of the fluorine atoms will accept one electron from magnesium and becomes negatively charged anion having one unit negative charge.

Now both the cation and anion are attracted by the coulombic force of attraction and forms magnesium chloride.

weight of the box is given as

here this is placed on the inclined of angle 42 degree

now this weight will have two components one is along the incline other is perpendicular to it

so here we need to apply a force parallel to incline opposite to its component of weight

so here the component of weight is given as

here we have

so it requires 75 n force to move it upwards
