Answer:

They're charged particles Identical to the Helium Nucleus

Having 2 protons and 2neutrons and having a Mass of 4.

They're Heavy and slow(speed)In comparison to Beta particles and gamma rays

Usually Emitted from nucleus of radioactive nuclides during decay

Here is an example though:
If you were given NaCl (this is he chemical formulafor table salt) you could identify Na (first column, or group, on your periodic table (PT) and 2nd row, or period, on your PT) as sodium.
The Cl you could identify as Chloride.

Answer:

2000 years

Explanation:

A radioactive molecule will continuously decay and turn into another molecule. This nature of the radioactive molecule makes them can be used to estimate the age of an object. Half-life is the unit of time needed for radioactive molecules to decay to half of its mass. The formula for the mass remaining will be:

$N(t)= N_{0} (\frac{1}{2})^{\frac{t}{t_{1/2} } }$

Where

N(t)= number of the molecule remains

N0= number of molecule initially

t= time elapsed

t1/2= half time

We have all variable besides the half time, the calculation will be:

$N(t)= N_{0} (\frac{1}{2})^{\frac{t}{t_{1/2} } }$

$0.125= 1 (\frac{1}{2})^{\frac{6000}{t_{1/2} } }$

$(\frac{1}{8})= (\frac{1}{2})^{\frac{6000}{t_{1/2} } }$

$(\frac{1}{2})^3= (\frac{1}{2})^{\frac{6000}{t_{1/2} } }$

3= 6000/ (t1/2)

t1/2= 6000/3= 2000

The half-life is 2000 years
