Question

A stable atom that has a large nucleus most likely contains

1. more neutrons than protons.
2.more protons than neutrons.
3.equal numbers of protons and neutrons.
4.changing numbers of protons and neutrons.

Answer 1

1. more neutrons than protons

Step-by-step explanation:

I got it right on edge

Answer 2

3. Equal numbers of protons and neutrons

Step-by-step explanation:

The nucleus becomes unstable if the ratio of protons to neutrons is less than 1:1 or more than 1:1.5.

The most stable nucleus has a neutron proton ratio of 1:1 which means that they can not release a neutron or a proton to decay.

Nucleus 3 is therefore the most stable.
