1. Based on Dalton's atomic theory, which of the following is true about all atoms of the same element?

They have different masses.
They have the same properties.
They can be divided into molecules.
They are composed of visible matter.

2. Boron is to the immediate left of carbon in the same row in the periodic table. Which of the following statements compares the radius and pull exerted by the protons of boron and carbon atoms?

Boron has a smaller radius and the protons in carbon exert a greater pull.
Boron has a larger radius and the protons in carbon exert a greater pull.
Boron has a smaller radius and the protons in carbon exert less pull.
Boron has a larger radius and the protons in carbon exert less pull.

Answer 1:
The corret option is that they have same properties.
Reason:
According to Dalton atomic theory an element is made from identical atoms having same chemical properties but different physical properties.

Answer:
The correct option is that boronhas a larger radius and the proton in carbon exert a greater pull
Reason:
According to trends in periodic table if move from left to right of periodic table along rows, nuclera charges increse as a result atomic radius decreases. Boron is present in group 3rd A while carbon is present in group 4th A. Thats why boron has has a larger atomic radius and carbon has smaller atomic radius due to greater nuclear charges.
