Rohan, James, and Arjun are studying chemistry and they come across a question. Why do most elements create chemical bonds in a scenario like when Sodium (Na) reacts with Chlorine (Cl) to form Sodium Chloride (NaCl)?

• To gain electrons, so that each element like Sodium or Chlorine has more electrons.

• To equal the number of protons and electrons in elements like Sodium or Chlorine.

• To stop radioactive decay in elements like Sodium or Chlorine.

• To reach eight valence electrons, which makes elements like Sodium or Chlorine stable.

Mason, Noah, and Priya are studying chemistry. They learned that when an atom gains an electron, it becomes an ion. If an atom gains one electron, what charge will it have as an ion?

• +1

• -1

• Zero

• -2

Rohan, Benjamin, and Ethan are in a science class learning about the periodic table. The teacher asks, 'Where are metals located on the periodic table?'

• In the blue section

• In the orange section

• In the yellow section

• In the red section

Avery, Olivia, and Grace are studying chemistry. They learned that calcium can become a calcium ion. Avery thinks it happens when calcium loses 2 electrons. Is Avery correct?

• Yes, calcium becomes a calcium ion by losing 2 electrons

• No, calcium becomes a calcium ion by gaining 2 electrons

• No, calcium becomes a calcium ion by losing 1 electron

• No, calcium becomes a calcium ion by gaining 1 electron

Lily, Abigail, and Ava are working on a science project about elements. They are discussing whether hydrogen is considered a metal, a non-metal, or a metalloid. What should they conclude?

• non-metal

• metal

• metalloid

Ethan, Nora, and Abigail are studying chemistry together. They are discussing the type of chemical bonds that occur when atoms share electrons. What type of bond are they discussing?

(a)  

Aria and David are studying chemistry together. They came across a type of chemical bond where atoms transfer electrons (either gain or lose). What is this type of bond called?

(a)  

Grace, Emma, and Evelyn are working on a science project. They need to decide what kind of bond would form between two nonmetals. What should they choose?

• Ionic Bonds

• Covalent Bonds
