The same element can have different half-lives, for different isotopes. You can find a list at the Wikipedia article "List of radioactive isotopes by half-life". This list is NOT complete; a complete list would have about 3000 nuclides (that is, isotopes).
That depends on the "half-life" of that particular radioactive element, which the question forgot to state. They're all different. Various radioactive elements have half-lives ranging from microseconds to millions of years.
Life would be drastically different without combustion, as it is the primary process that powers most of our transportation, heating, and energy production. We would rely more on alternative energy sources like solar, wind, and hydropower, which may lead to cleaner air and reduced environmental impact. However, we would need to develop new technologies and infrastructure to adapt to this change.
The basic elements of life are carbon, hydrogen, oxygen, nitrogen, phosphorus, and sulfur. These elements make up the building blocks of biological molecules such as DNA, proteins, and carbohydrates that are essential for life. Without these elements, living organisms would not be able to carry out essential functions or sustain life.
The half-life of an element is the time it takes for half of a sample to decay. It is specific to each element. The half-life of carbon-14 is 5730 years, whereas the half-life of element Z would depend on the specific element and is not necessarily comparable to carbon-14.

Magnesium is a key element in Chlorophyll and without it life as we know it would cease
Without xenon, we would lose some of its uses in lighting, medical imaging, and laser technology. However, its absence would not significantly impact life's essential functions or daily activities since xenon is a rare and non-essential element in most applications.

Life without silicon would be drastically different as silicon is a crucial element for many technological devices like computers, phones, and solar panels. It is also found in many natural materials like rocks and sand. Without silicon, the development of modern technologies would be severely limited, and alternative materials would need to be explored for various applications.
Without knowing the element and the specific isotope, this has no answer.
people would live alot diffrent lives and we would have diffrrent cities and communites. we would eat differently and live our lives without alot of things. there you have your answer fo "how would life be different without the construction fo the us?"
Life without pi would be different. M&M's would be square, the world, door knobs, most fruit, car tires, water bottle lids, marker caps and a lot more. Life without pi would be different to everyone, and would sure be hard to get used to.

Most likely we would be a monarchy of some sort.
