A molecule in which the central atom forms three single bonds and has one lone pair is said to have a ________ shape.
nignag [31]

Answer : The correct option is, (c) pyramidal

Explanation :

As we are given that a molecule in which the central atom forms three single bonds and has one lone pair that means the central metal atom has 3 bond pairs and 1 lone pair of electrons.

There are total 4 electron pairs. So, the hybridization will be sp^3 and the electronic geometry of the molecule will be tetrahedral.

But as there are three atoms or bonds around the central atom and the fourth position occupied by lone pair of electrons. The repulsion between lone and bond pair of electrons is more and hence the molecular geometry will be pyramidal.

Hence, correct option is, (c) pyramidal

Lithium and fluorine undergo ionic bonding. Using the noble gas electron configurations for each (below), please explain the pro
Slav-nsk [51]

Answer:

Lithium loses one electron to fluorine and forms ionic bond, having formula LiF.

Explanation:

Lithium is the element of the group 1 and period 2 which means that the valence electronic configuration is [He]2s^1.

Fluorine is the element of the group 17 and period 2 which means that the valence electronic configuration is [He]2s^22p^5.

<u>Thus, lithium loses 1 electron and become positively charged. Fluorine on the other hand accepts this electron and become negatively charged.</u> This is done in order that the octet of the atoms are complete.  <u>These both ions then form ionic bond as their will be electrostatic interaction between the two oppositely charged ions.</u>

Thus, the formula of calcium chloride is LiF.

What is the limiting reactant when 8.4 moles of lithium react with 4.6 moles of oxygen gas?
serious [3.7K]

Answer: Lithium

Explanation: The balanced chemical equation is:

4Li+O_2\rightarrow 2Li_2O

It can be seen, 4 moles of lithium combines with 1 mole of oxygen gas to produce 2 moles of lithium oxide.

Thus 8.4 moles of lithium combines with=\frac{1}{4}\times {8.4}=2.1molesof oxygen gas to produce 4.2 moles of lithium oxide.

As, Lithium limits the formation of product, it is the limiting reagent and Oxygen gas is present in excess, it is called the excess reagent. (4.6-2.1)=2.5 moles of oxygen gas are present in excess.

Which atomic property is different in each isotope of an element?
Valentin [98]
Every isotope of an element has a different number of neutrons, which means that the atomic property which is different in each isotope of an element is mass number.
Mass number depends on the number of neutrons in an element.
