Answer

Brief Explanations:

  1. Alkali metals: Lithium (Li), Sodium (Na), Potassium (K); Alkaline - earth metals: Beryllium (Be), Magnesium (Mg), Calcium (Ca); Halogens: Fluorine (F), Chlorine (Cl), Bromine (Br); Noble gases: Helium (He), Neon (Ne), Argon (Ar).
  2. An atom model typically shows a nucleus in the center with protons and neutrons inside it, and electrons orbiting around the nucleus.
  3. A gluon is a theoretical particle in quantum chromodynamics and is often represented in diagrams related to the strong - force interactions between quarks. However, it is not possible to draw a "real - world" picture as it is a sub - atomic particle not directly observable in the traditional sense.
  4. Alpha radiation consists of helium - 4 nuclei (2 protons and 2 neutrons), while beta radiation is either an electron (beta - minus decay) or a positron (beta - plus decay). Alpha particles are relatively large and slow - moving compared to beta particles which are smaller and faster.
  5. Fe (Iron) is in Group 8; F (Fluorine) is in Group 17; O (Oxygen) is in Group 16; Cu (Copper) is in Group 11.

Answer:

  1. Lithium (Li), Sodium (Na), Potassium (K); Beryllium (Be), Magnesium (Mg), Calcium (Ca); Fluorine (F), Chlorine (Cl), Bromine (Br); Helium (He), Neon (Ne), Argon (Ar)
  2. A model with nucleus containing protons and neutrons, electrons orbiting around it.
  3. Not possible to draw a direct picture as it's a theoretical sub - atomic particle.
  4. Alpha radiation is helium - 4 nuclei, beta radiation is an electron or positron. Alpha particles are larger and slower.
  5. Fe: Group 8; F: Group 17; O: Group 16; Cu: Group 11
