The statements which best describe beta decay are: option 1, 2 and 4.

<h3>What is a beta particle?</h3>

A beta particle can be defined as an isotope which typically undergoes radioactive decay through the emission of a radiation with a -1 charge.

Based on scientific information and records from radioactivity, we can infer that the statements which best describe beta decay are:

  • During beta decay, an atom of proton becomes a neutron and a positron.
  • During beta decay, an atom of neutron becomes a proton and an electron.
  • Beta decay releases energy.

Zolol [24]

The Copernican revolution is about the model of the solar system and was given by a polish astronomer. Option C. The discovery that the universe was expanding.

The Copernican Revolution become the paradigm shift from the Ptolemaic model of the heavens, which described the cosmos as having Earth stationery on the center of the universe, to the heliocentric version with the solar on the center of the solar system.

Copernican Revolution, shift the subject of astronomy from a geocentric understanding of the universe, focused around Earth, to heliocentric knowledge, concentrated across the sun, as articulated by the Polish astronomer Nicolaus Copernicus.

This revolution changed the way of thinking of the solar system. Earlier it was thought that earth is in the center of the solar sysytem,i.e; people believed in the geocentric model, but according to Copernicus the solar system has the sun at the center and the remaining planets revolve around it i.e he believed in a heliocentric model.

Based on Reference Table S, the atoms of which of these elements have the strongest attraction for electrons in a chemical bond?
BabaBlast [244]
Answer is (1) - N

<em>Explanation:</em>

I think the given chart is electronegativity chart.

Electronegativity is a value that tells us how an atom can attract electrons towards itself. <span><u>If the electronegativity is high, then the attraction to the electrons is high unless the attraction to the electrons is low. </u>

Electronegativity increases from left to right of the periodic table and decreases from up to down. 
Hence, highest electronegative atom is F which has 4.0 and lowest electronegative atoms are Cs and Fr (0.7).

The electronegativity values for given atoms are
  N - 3.0
  Na - 0.9
  P - 2.1
  Pt - 2.2 </span>
