Which pair of elements will form a covalent bond?O potassium and chlorine
O carbon and sulfur
O aluminum and chlorine
O
lithium and oxygen
Answers
Answer 1
Answer:
Answer: Option (b) is the correct answer.
Explanation:
A covalent bond is defined as the bond formed between the two atoms due to sharing of electrons.
A covalent bond is always formed between non-metals.
For example, carbon and sulfur are both non-metals and when they chemically combine together they form which is a covalent compound.
Thus, we can conclude that out of the given options carbon and sulfur is the pair of elements that will form a covalent bond.
Answer 2
Answer:
The answer is most likely carbon and sulfur since both of those are nonmetal covalent elements.

Only the number of protons determine the type of atom. Elements can have more or less neutrons and electrons and still be the same general type of element.
The number of protons, neutrons and electrons an atom has determines what element it is. Hydrogen, for example, has one proton, no neutrons and one electron; the element sulfur has 16 protons, 16 neutrons and 16 electrons.

Answer:
The correct answer is: Alkali Metals
Explanation:
The chemical elements that belong to the group 1 of the periodic table are known as the alkali metals. The alkali metals belong to the s-block and are highly reactive in nature.
The alkali metals are lithium (chemical symbol Li), sodium (chemical symbol Na), potassium (chemical symbol K), rubidium (chemical symbol Rb), caesium (chemical symbol Cs), and francium (chemical symbol Fr).
Therefore, lithium, sodium, potassium are examples of alkali metals.
Metals in the periodic table.
