Good luck my fellow summer school students, I love you all.
Please rate, thanks, & vote brainliest, I want a rank up already.
(2) low first ionization energy and high electronegativity
(3) high first ionization energy and low electronegativity
(4) high first ionization energy and high electronegativity
Answer:
low first ionization energy and low electronegativity
Explanation:
Metals are typically characterized by low first ionization energy and low electronegativity. This is because metals can easily lose electrons to become positive ions and do not attract electrons strongly.
Two properties that are typically associated with metals are low first ionization energy and low electronegativity. Therefore, the correct option is (1).
Ionization energy is the energy required to remove an electron from an atom. Metals have low first ionization energy because they can easily lose an electron to become positive ions. Electronegativity is a measure of the ability of an atom to attract electrons. Metals have low electronegativity because they do not attract electrons strongly.
