a
Neon
b
Fluorine
c
Calcium
d
Iron
Question 24
Match the part of an atom to its description.

Column A
1.
proton:
proton
2.
neutron:
neutron
3.
electron:
electron
4.
nucleus:
nucleus
5.
electron cloud:
electron cloud
Column B
a.negatively charged particle
b.positively charged particle
c.neutral particle
d.the area of the atom where negatively charged particles are found
e.the area of the atom where positive particles and neutral particles are found

1 answer

Question 23: The most electronegative element among the options is:

b. Fluorine

Fluorine has the highest electronegativity of any element on the periodic table. Electronegativity generally increases across a period from left to right and decreases down a group.

Question 24: Here is the correct matching of parts of an atom to their descriptions:

  1. proton: b. positively charged particle
  2. neutron: c. neutral particle
  3. electron: a. negatively charged particle
  4. nucleus: e. the area of the atom where positive particles and neutral particles are found
  5. electron cloud: d. the area of the atom where negatively charged particles are found
