Pls The electronic configuration of an element is given below. Element 1: 1s22s22p4

Which statement about the reactivity of the element is true?

It is reactive because it has to gain an electron to have a full outermost energy level.

It is unreactive because it has to lose an electron to have a full outermost energy level.

It is reactive because it has to gain two electrons to have a full outermost energy level.

It is unreactive because it has to gain two electrons to have a full outermost energy level.

the relative standard reduction potential of the half-cell in which reduction occurs; more positive than the other half-cell. reduction is a chemical process in which electrons are added to an atom or an ion; it always occurs accompanied by oxidation of the reducing agent.

an organism's phenotype is the  form of a trait  that it  displays. for  flowercolor, a pea  plant  can  display  a phenotype of purple or white flowers. an organism's  genotype  is the alleles of a gene it contains. based on his data, mendel concluded that a phenotype can be  determined  by more than one  genotype.
