give 2 advantages of using modern symbols rather than dalton's symbols.

1. Modern symbols are easier to write and read: Modern symbols are often simpler and more intuitive than Dalton's symbols, making them easier to write and read. For example, the modern symbol for oxygen (O) is more concise and straightforward than Dalton's original symbol, which used circles and lines to represent the atom's structure.

2. Modern symbols are more accurate: Modern symbols accurately reflect the known properties and behaviors of different elements. For example, the modern symbol for helium (He) accurately reflects its inert, non-reactive nature, while Dalton's original symbol (which used a circle with an inner circle) did not convey this information. This precision and accuracy are important for scientific understanding and communication.
