Answer:
It becomes a positive ion and its radius decreases
Explanation:
As per the Octet rule, Barium has 2 electrons in its outermost shell. When it loses the two electron it gains two positive charge i.e Ba2+. As the barium loses the two electron from its outermost shell, the outermost shell becomes vacant and thus is no more considered as a part of atomic geometry of the barium atom and since the outermost shell is considered negligible the radius of barium atom reduces automatically.
C. Vinyl or neoprene gloves provide protection against hazardous chemicals due to their resistance to chemical exposure. Latex gloves can be permeable, and padded cloth gloves are not designed for chemical protection.
C. Vinyl or neoprene gloves are the appropriate choice for protecting hands from hazardous chemicals. Here's why:
1. Chemical Resistance: Vinyl and neoprene gloves offer excellent resistance to a wide range of chemicals, including acids, bases, solvents, and oils. This resistance creates a barrier that prevents hazardous chemicals from coming into contact with your skin.
2. Latex Allergies: Latex gloves (option A) can cause allergic reactions in some individuals, which can be severe. It's important to avoid latex gloves when working with hazardous chemicals to prevent potential allergic responses.
3. Physical Protection: Padded cloth gloves (option B) are typically designed for physical protection and comfort, not for chemical resistance. They may not provide an effective barrier against chemical exposure, making them unsuitable for this purpose.
4. Versatility: Vinyl and neoprene gloves are versatile and can be used in various laboratory, industrial, and healthcare settings where protection against chemical hazards is necessary.
5. Durability: These gloves are known for their durability and resistance to wear and tear, ensuring that they maintain their protective properties even during prolonged use.
It's essential to choose the right type of gloves based on the specific chemicals you are handling and their compatibility with the glove material. Always consult safety guidelines and material compatibility charts to select the most appropriate gloves for your specific chemical-handling tasks, ensuring the safety of your hands and skin.

the correct answer would be A. Latex Gloves. vinyl or neoprene gloves will be eaten by most highly toxic chemicals and some lower toxicity chemicals and padded cloth gloves will just soak up the chemical.
hope this helps:)
