Answer:

Chemical reactivity increases down a group and decreases from left to right of a period.

Explanation:

The higher the ionization energy is, the lower the reactivity is. Since the ionization energy is highest in the top right corner of the periodic table, we can assume that the most reactive elements are in the opposite bottom left corner. This is because the electrons that react are farther away from the nucleus thus experience less attraction to the nucleus (called nuclear shielding). Therefore their electrons are more easily removed than elements that don't ecperience nuclear shielding.

In a redox reaction, the substance that accepts electrons is said to be

brilliants [131]

The substance doesn't have a specific name. We just say that that substance is being reduced. Remember this mnemonic - OILRIG where "Oxidation is Loss, Reduction is Gain" of electrons.

Answer: has zero mass

is an electron

has a -1 charge

is electromagnetic energy

Explanation:

A beta-particle is an electron emitted from the nucleus of an atom following the decay of a neutron into a proton. Beta rays are deflected by a magnetic field in a direction that indicates a negative charge, thus they are electromagnetic in nature.

The beta particle released is basically a electron with -1 charge and no mass.

General representation of beta particle in the form of $_Z^A\textrm {X}$ given as $_{-1}^0e$

where,

Z represents Atomic number

A represents Mass number

X represents the symbol of an element
