The correct answer is aluminium.

Beta radiation consists of electrons that are ejected by the nucleus. Beta particles have the charge of an electrons and the mass of an electron. Beta particles are quite small , giving them the ability to travel through materials a bit longer before collisions with other particles makes them stop hence they can not be stopped by skin, a piece of paper and thin fabric. Their size accounts for why they have more penetration abilities than alpha particles which are large and can be stopped by a thin piece of paper. However, it is known that a few millimeters of aluminium sheet is able to stop beta particles.

The correct answer is aluminium.

D) energy required to remove a valence electron

Explanation:

The ionization energy is the energy required to remove a valence electron from an element.

Different kinds of atoms bind their valence electrons with different amount of energy.

To remove the electrons, energy must be supplied to the atom.
The amount of energy required to remove the an electron in the valence shell is the ionization energy or ionization potential.
The first ionization energy is the energy needed to remove the most loosely bound electron in an atom in the ground state.
The ionization energy measures the readiness of an atom to loose electrons.

Which scientist discovered that the atomic number, rather than the atomic weight, is more responsible for the properties of an e

myrzilka [38]

<em>Answer:</em>

The correct option is Moseley who has discovered the atomic number.

<em>Explanation:</em>

In 1913, H. Moseley discovered a new properties of an element atomic number. He observed that elements in the periodic table can be arranged better according to atomic number rather than atomic mass.
The atomic number of any elements is always equal to numbers of electrons in it.
