3 is C i believe, and as for 4 minerals are solid, natural.. that's about all I can say...
An electron can be added to halogen atom to force a halide ion with 8 valence electrons
<h3>What is an atom?</h3>
An atom can be defined as the smallest part of an element which can take part in a chemical reaction.
However whenever, an electron is added to halogen atom to force a halide ion with 8 different valence electrons
So therefore; an electron can be added to halogen atom to force a halide ion with 8 valence electrons

The correct option is C.
The pitch of a string refers to the quality of sound that is produced by the string when it vibrates. There are three basic factors that affect the quality of pitch of a string, these are: the tension, the thickness of the string and the length of the string. The higher the thickness of the string, the lower the pitch of the string, thus, increasing the thickness of the string will lower the pitch.
Based on the data given, the energy required to remove an electron from a hydrogen atom in the n = 11 state is -0.112 eV
<h3>What is ionization energy?</h3>
Ionization energy is the energy requiredto remove an electron from a neutral atom or a cation in its gaseous state.
To calculate the energy required to remove the electron from a hydrogen atom in the n = 11 state, the formula below is used:
where
substituting the values:
Therefore, the energy required to remove an electron from a hydrogen atom in the n = 11 state is -0.112 eV
