Two elements that have the same ground-state valence shell configuration of ns 2 np 2 are

Chemistry

kvv77 [185]1 year ago
6 0

Answer:

carbon and silicon

Explanation:

Various groups of elements in the periodic table have different outermost shell electron configurations. Actually, elements are classified into groups on the basis of the number of electrons on the outermost shell of those elements. All elements with the same number of electrons on their outermost shell belong to the same group in the periodic table.

For elements in group 14, they all have four electrons on their outermost shell. Their general outer electron configuration is ns2 np2 as shown in the question. Two prominent members of this group are carbon and silicon. This ns2 np2 is the ground state outer electron configuration of all group 14 elements in the periodic table.

What is the axmen classification for benzene (C6H6)?
Tatiana [17]

Answer is: Benzene is trigonal (or triangular) planar.

VSEPR theory (The Valence Shell Electron Pair Repulsion Theory) uses the AXE notation (m and n are integers, m + n = number of regions of electron density).

For benzene molecule (C₆H₆):

m = 3; the number of atoms bonded to the central atom.

n = 0; the number of lone pairs on the central atom.

Which of the following species contains manganese with the highest oxidation number?
ioda

In NaMnO₄, Mn has the highest oxidation number.

The question is incomplete, the complete question is;

Which of the following species contains manganese with the highest oxidation number?

A) Mn

B) MnF₂

C) Mn₃(PO₄)₂

D) MnCl₄

E) NaMnO₄

In order to ascertain the specie that contains manganese with the highest oxidation number, we must calculate the oxidation number of manganese in each of the species one after the other.

1) For Mn, the oxidation number of Mn is zero because the atom is uncombined.

2) For MnF₂;

Mn has an oxidation number of +2

3) For Mn₃(PO₄)₂

Mn has an oxidation number of +2

4) For MnCl₄

Mn has an oxidation number of +4

5) For NaMnO₄

Mn has an oxidation number of +7

Hence in NaMnO₄, Mn has the highest oxidation number.

An ice cube is dropped into a glass of milk at 20°C. Which statement explains the transfer of kinetic energy (KE)?
hoa [83]

Answer:

Because milk has higher KE than ice, KE is transferred from the milk to the molecules of ice.

Explanation:

The best statement that expresses the transfer of kinetic energy(K.E) is that kinetic energy is transferred from the milk to the ice.

Kinetic energy is form of energy due to motion of the particles of a medium. In this regard, we are dealing with heat energy.

  • Heat energy is dissipated from a body at higher temperature to one at a lower temperature.
  • Ice is at a lower temperature which is 0°C
  • Heat will be transferred in form of thermal energy from the body at higher temperature to one with a lower temperature.
  • This is from the milk to the molecules of ice.
