Front

What is atomic radius?

Back

The atomic radius is the distance from the nucleus of an atom to the outermost shell of electrons. It generally increases down a group and decreases across a period.

Front

What trend is related to the size of an atom?

Back

Atomic radius is the trend related to the size of an atom.

Front

Which element has a higher ionization energy, F or Sc?

Back

Fluorine (F) has a higher ionization energy than Scandium (Sc) due to its higher effective nuclear charge and smaller atomic size.

Front

What are the chemical properties of elements in the same group?

Back

Elements in the same group of the periodic table have similar chemical properties due to having the same number of valence electrons.

Front

What is ionization energy?

Back

Ionization energy is the energy required to remove an electron from an atom in its gaseous state.

Front

What is the electron configuration of Manganese (Mn)?

Back

The electron configuration of Manganese (Mn) is 1s² 2s² 2p⁶ 3s² 3p⁶ 4s² 3d⁵.

Front

What is alpha decay?

Back

Alpha decay is a type of radioactive decay in which a parent nucleus emits an alpha particle, consisting of 2 protons and 2 neutrons.

Front

What is beta decay?

Back

Beta decay is a type of radioactive decay in which a neutron is transformed into a proton, emitting a beta particle (electron) and an antineutrino.

Front

What is gamma decay?

Back

Gamma decay is a type of radioactive decay that involves the emission of gamma rays, which are high-energy photons, from a nucleus.

Front

What is electronegativity?

Back

Electronegativity is a measure of the tendency of an atom to attract a bonding pair of electrons.
