Which metalloid has five electrons in the fourth electron shell?The fourth electron fills the remaining space in the 2s orbital. An atom of boron (atomic number 5) contains five electrons.
What element in the 4th period has 5 valence electrons?In general, the group number represents the number of valence electrons in a representative element. Therefore, the element in the fourth period of the periodic table which has five valence electrons is Arsenic.
What element is a metalloid with 5 valence electrons?Arsenic (As) (Figure below) and antimony (Sb) are the metalloids in this group, and bismuth (Bi) is a metal. All group 15 elements have five valence electrons, but they vary in their reactivity.
Which element has 5 electrons in the valence shell?Atoms in the nitrogen family have 5 valence electrons. They tend to share electrons when they bond. Other elements in this family are phosphorus, arsenic, antimony, and bismuth.
