Answer 1

$\huge\pink{\boxed{\green{\mathfrak{\overbrace{\underbrace{\fcolorbox{red}{aqua}{\underline{\pink{✯Answer✯}}}}}}}}}$

Each helium atom has two electrons in 1s-orbital and therefore, there are four electrons in He2 molecule. These electrons will be accommodated in si1ls and s*1s MOs as shown below. The zero bond order value indicates that there is no net bonding and He2 molecule should not be formed.
