The first two factors change the effective nuclear charge the most loosely held electron feels.

In effect each bomb would be a nuclear shaped charge.

There wasn't time to worry about whether Gadgets had attained a low order explosion with the nuclear charge.

Historically, the effective nuclear charge was estimated by Slater's rules.

She felt the host-entity gathering, waiting, building up a nuclear charge.

In this case, the effective nuclear charge can be calculated from Coulomb's law.

A few had been scuttled, blown apart by nuclear charges; not much remained of those.

No international problem requires such a quantity of nuclear charges and missiles.

You do not use a nuclear charge to kill a hundred people.

This makes sense, since it has a significant nuclear charge, very little screening, and a small radius.
