What happens to the half-life and mass of reactants broken down during a nuclear decay reaction?

a) the half-life of reactants in a nuclear decay reaction remains constant over time, but the mass of reactants that are consumed decreases.

b) the half-life of reactants in a nuclear decay reaction increases over time, and the
mass of the reactants that are consumed increases.

c) the half-life of reactants in a nuclear decay reaction decreases over time, but the
mass of the reactants that are consumed stays the same.

d) the half-life of the reactants in a nuclear decay reaction remains constant over time,
and the mass of the reactants that are consumed stays the same.

the transfer of heat by electromagnetic radiation is called thermal radiation . it is usually carried out by electromagnetic waves in an energy range just below the visible spectrum, which is the infrared range.

so the answer would be radiation.

answer: atomic mass was originally used to arrange elements on the periodic table, but is no longer used to organize the modern version.

explanation:

originally atomic mass was used to arrange elements on the periodic table from left to right in a row. each column then shows similar properties of elements of a group.

in modern periodic table, the atoms are arranged in increasing atomic number. as atomic number represents the number of protons in an atom which is unique for every atom.
