Travka [436]
The outer planets are <span>Jupiter, Saturn, Uranus and Neptune while the inner planets are Mercury, Venus, Earth, and  Mars. The outer planets have more moons than the inner planets because these planets are much larger than the inner ones. The inner planets are terrestrial while larger ones are called gas giants, mostly made up of gas.</span>

Submit Quiz Previous Page 1 of 4 Next Drag and drop each description to match the subatomic particle. Protons Neutrons Drag and
Pavel [41]

Answer:

<em>Protons: </em>

  • Positively charged particle
  • The number of these is the atomic number
  • All atoms of a given element have the same number of these

<em>Neutrons:  </em>

  • Neutral particles  
  • Isotopes of a given element differ in the number of these
  • The mass number is the number of these added to the number of protons

Explanation:

Protons (<em>positively charged</em>), neutrons (<em>neutral</em>) and electrons (negatively charged) are smaller than an atom and they are the main subatomic particles.  The nucleus of an atom is composed of protons and neutrons, and the electrons are in the periphery at unknown pathways.

The <em>Atomic number</em> (Z) indicates the number of protons (P^{+}) in the nucleus. Every atom of an element have the <em>same atomic number</em>, thus the <em>same number of protons</em>.

The <em>mass number </em>(A) is the sum of the <em>number of protons</em>  (P^{+}) <em>and neutrons</em> (N) that are present in the nucleus: <em>A= Z + N</em>

<em>Isotopes</em> are atoms of the <em>same element </em>which nucleus have the <em>same atomic number</em> (Z), and <em>different mass number (A)</em>, it means the <em>same number of protons</em> (P^{+}) and a <em>different number of neutrons</em> (N). For example, the oxygen in its natural state is a mixture of isotopes:

99.8% atoms with A= 16, Z=8, and N=8

0.037% atoms with A=17, Z=8, and N=9

0.204% atoms with A=18, Z=8, and N=10
