Which two elements have the most similar chemical properties.

answer:

which two elements have the most similar chemical properties?

(1) beryllium and magnesium

(2) hydrogen and helium

(3) phosphorus and sulfur

(4) potassium and strontium

answer: the correct answer 1: beryllium and magnesium

both elements appear on the same group (ii),and therefore have the most similar chemical properties.

explanation:

answer:

na (sodium) and rb (rubidium) have the most similar chemical properties. they're both alkali metals, found in the first column of the periodic table.

explanation:

hope this

answer: option (b) is the correct answer.

explanation:

a covalent bond is formed by sharing of electrons. whereas polarity arises due to difference in electronegativity of two atoms.

therefore, more is the electronegativity of an atom which combines with the titanium, more readily it will induce a partial positive and negative charge.

thus, out of the given options fluorine is most electronegative and has an incomplete octet. therefore, it will readily combine with titanium to share the electrons and complete its octet.
