Question

group number valence electrons and Lewis dot structure of beryllium​

Answer 1

Answer:

The number of dots in the Lewis dot symbol is the same as the number of valence electrons, which is the same as the last digit of the element's group number in the periodic table. ... Lewis used the unpaired dots to predict the number of bonds that an element will form in a compound

Answer 2

Answer:

Group 13 has three valence electrons, Group 14 has four, up through Group 18 with eight. ... A beryllium atom, with two valence electrons, would have the electron dot diagram below. Since electrons repel each other, the dots for a given atom are distributed evenly around the symbol before they are paired.
