Answer:

the blanket of gases that surrounds Earth and some other planets

Explanation:

The best definition of the atmosphere is that it is a portion of the earth that is a made up of a blanket of gases.

  • The atmosphere is not peculiar to the earth alone, some other planets also have atmospheric cover.
  • The earth's atmosphere is divided into many different layers.
  • The weather we see and experience on the earth surface is conditioned within the troposphere.
  • This troposphere is the closest layer to the surface.

Which of the following statements are TRUE?
SCORPION-xisa [38]

Answer:

Answered

Explanation:

1)False,  electron carriers are not  located at ribosomes.

2) True, ATP is the common intermediate between catabolic and anabolic pathways.

3)False,  ATP is used for the long-term storage of energy and so is often not found in storage granules.

4) True, Anaerobic organisms are capable of generating ATP via respiration.

5) True , ATP can be generated by the flow of protons across protein channels.

What are the period and group trends in electronegativities
Leviafan [203]

Electronegativity of an element decreases as we move down a group on the periodic table and electronegativity increases while moving from left to right across a period on the periodic table.

Explanation:

  • The electronegativity increases as we move from left to right across a period because from left to right across a period, the nuclear charge is increasing Hence the attraction for the valence electrons also increases.
  • As we move down a group, the atoms of each element have an increasing number of energy levels. The distance between the nucleus and valence electron shell increases and reduces the attraction for valence electrons. Hence electronegativity decreases as we move from top to bottom down a group.

An aluminum cation is smaller than the aluminum atom because it has fewer occupied energy levels. True false
butalik [34]

The molecules or atoms that are formed by gain or loss of one or more valence electrons are said to be ions.

When atom loss one or more valence electrons, results in formation of cation whereas when atom gain one or more valence electrons, then formation of anion occurs. Cations carry positive charge and anions carry negative charge.

In general, cations are smaller than the neutral atoms from which they are formed and anions are larger than the neutral atoms.

As cations are smaller than the related neutral atoms because the valence electrons are lost which are farthest away from the nucleus. After that, taking more electrons distant from the cation results in reduction of radius of the ion.

Thus, aluminium cation consist of few electrons which results in fewer occupied energy levels by the electrons further results in reduction of radius i.e. smaller size.

Hence, given statement is true i.e. aluminium atom is larger than the aluminium cation as cation has fewer occupied energy levels.
