Ms sue, can you help me with these?
I'll be glad to check your answers.
Be sure to study your text before you post them.
I was clueless that's why I needed help. I don't understand this.
Of course, I'll help you with these questions! Let's go through them one by one.
1. Dalton's idea that atoms cannot be divided into smaller parts was disproved by the discovery of __________?
To answer this question, we need to know what discovery showed that atoms can be divided. This discovery is attributed to J.J. Thomson, who discovered the electron. He found that atoms can be divided into even smaller particles. So, the answer is electrons.
2. The description of the structure of the atom is called the __________?
The description of the structure of the atom is called the atomic model. Scientists have developed different atomic models over time to explain the arrangement of subatomic particles within an atom.
3. In a water molecule, two atoms of hydrogen and one atom of oxygen share electrons. A __________ bond is found in a water molecule.
To determine the type of bond in a water molecule, we need to understand the concept of bonding. When atoms share electrons, it forms a covalent bond. So, the answer is a covalent bond.
4. Sodium chloride is formed when the metal sodium bonds with the nonmetal chloride. The atoms are held together by a(n) __________?
When a metal bonds with a nonmetal, they form an ionic bond. In the case of sodium chloride, sodium donates an electron to chloride, creating charged ions that are attracted to each other. So, the answer is ionic bond.
5. One way the modern atomic model differs from Thomson's atomic model is that electrons are no longer scattered throughout an atom's positive matter like chocolate chips in cookie dough. Instead, each electron is outside the nucleus, occupying a specific __________?
In the modern atomic model, electrons exist in specific regions around the nucleus called energy levels, orbitals, or shells. Each electron occupies a specific energy level depending on its distance from the nucleus and its energy state.
6. If new information about the behavior of atoms is discovered and verified, then revisions will need to be made in the current __________?
When new information is discovered and verified, it often leads to revisions in the current atomic model or theory. The atomic model is a scientific explanation of the structure and behavior of atoms, so it needs to be updated as our understanding of atoms evolves.
7. The number of protons in the nucleus of an atom is its __________?
The number of protons in the nucleus of an atom is its atomic number. It uniquely identifies each element on the periodic table.
I hope this helps! Let me know if you have any more questions.
