Question

1). How can the position of a particle be determined?

A-by measuring its mass

B-by determining its charge

C-by analyzing its interactions with another particle

D-by measuring its velocity


2). What is the mass number for an oxygen atom that has 10 neutrons in its nucleus?

A-16

B-8

C-18

D-10


3). What determines different shapes of an orbital?

A-speed

B-velocity

C-energy sub-level

D-all of the above

Answer 1

The position of a particle is determined by analyzing its interactions with another particle. The mass number for an oxygen atom with 10 neutrons is 18. Orbital shapes are determined by energy sub-levels, not by speed or velocity.

Step-by-step explanation:

To answer the set of questions provided, let's tackle each one individually:

1. The position of a particle can be determined C-by analyzing its interactions with another particle. Position cannot be directly found by measuring mass, determining charge, or measuring velocity alone.
2. The mass number for an oxygen atom that has 10 neutrons in its nucleus can be determined by adding the number of neutrons to the number of protons (which is 8 for oxygen), so the mass number is C-18.
3. Different shapes of an orbital are determined by C-energy sub-level, not by speed or velocity.

Each of these answers is directly linked to fundamental concepts of atomic structure and chemistry, focusing on the behavior of particles, the composition of elements, and the quantum mechanical nature of orbitals.
