What happens when an electron in its lowest energy level or ground state when it is by absorbs energy?

Chemistry
1 answer:
tester [92]3 years ago
8 0

Explanation:

atom changes from a ground state to an excited state by taking on energy from its surroundings in a process called absorption. The electron absorbs the energy and jumps to a higher energy level. In the reverse process, emission, the electron returns to the ground state by releasing the extra energy it absorbed

Iteru [2.4K]

Answer:

The two statements are all True for group 7 and 8 elements.

Explanation:

The Group 7 elements are known as the halogens. They are reactive non-metals and are always found in compounds with other elements. Chlorine, bromine and iodine are all halogens.

Chlorine, bromine and iodine are the three common Group 7 elements. Group 7 elements form salts when they react with metals. The term ‘halogen’ means 'salt former'.

In addition to the discription given to norble gases in the question which is true, norble gases;

  •     are inert gases located on the right of the periodic table.
  •     have a full-set of valence electrons, so they're stable, unreactive
  •     are colorless, odorless and tasteless.
  •     have low melting and low boiling points.
  •     can be found in small amounts in the Earth's crust and the Earth's atmosphere.

What is one similarity between metals and metalloids?
Arturiano [62]

The correct answer that explains similarities between metal and Metalloids as regards the question is They both conduct electricity

  • Metalloids can be regarded as elements that are  similar to metals, this is because they posses valence orbitals which is described as highly delocalized over macroscopic volumes.

  • As a result of this they can serve as electrical conductors.

  • metalloids posses small energy gap which is located between the valence band as well as the conduction band, as a result of this they are considered as  intrinsic semiconductors when compare to pure conductors like metal.

  • Example of metal is Calcium, sodium and that of Metalloids are silicon and  germanium

Therefore, metal and Metalloids are similar because of their conductivity of electricity

If 1.38×1022 atoms of element y have a mass of 1.50 g, what is the identity of y? express your answer as a chemical symbol.
zaharov [31]
1,38×10²² = 0,138×10²³

0,138×10²³ ----- 1,5g
6,02×10²³ ------ X
X = (1.5×6,02×10²³)/0,138×10²³
X = 65,435 g/mol

It's ZINC (Zn)
