An unstable nucleus, which can be caused by:
microscopic organisms are the major causes of decay.
No it does't!
The instability of the nuclei is the basic cause of radioactive decay.
decomposors
Beta+ decay and electron capture causes the atomic number to drop by one. Beta- causes the the atomic number to rise by one.Proton emission causes the atomic and mass number to drop by one.Neutron emission causes the mass number to drop by one.Alpha decay causes the atomic number to drop by two and the mass number to drop by four.
Radioactive Decay
radioactive
Microorganisms such as bacteria and fungi.
acids cause tooth decay u can prevent from drinking acidy drinks
sugar is the best answer
When you gag, this causes the teeth and gums to be touched by stomach acids. The acid causes the teeth enamel to wear away thus causing tooth decay.
The start of tooth decay is caused by two groups of bacteria Streptococcus Mutans and Lactobacillus.
