What are 3 main particles of an atom?
Proton, Electron, And neutron
100
What determines the atomic number of an element?
The number of protons in the nucleus of an atom.
100
What is the main difference between ionic and covalent compounds?
Iconic bonds transfers electrons
200
where are protons and electrons located within a atom?
in the center of the atom, making the nucleus.
200
What is the atomic number of Titanium (Ti)?
22.
200
Which type of compound typically has higher melting and boiling points?
ionic compounds
300
Predict the reactivity of an element with 7 valence electrons.
Very reactive.
300
Explain how the number of protons affects an element's position on the periodic table.
it increases.
300
Describe the process of how ionic compounds are formed.
If an atom has lost one or more electrons, it is positively charged.
400
Explain how the number of valence electrons influences an element's chemical properties.
Reactivity
400
How does electromagnetically change as you move down a group in the periodic table?
Decreases.
400
What structural feature of water contributes to its bent molecular shape?
how the shared electrons that are in bonds AND those that are NOT in bonds of the central oxygen atom are arranged in space to minimize electron repulsion
500
Why might elements with similar valence electron configurations exhibit similar chemical behavior?
Similar to lose, gain, or share electrons
500
How does understanding the properties of elements help in predicting chemical reactions in real-world applications?
helps by knowing which containers are safe for componds.
500
Analyze the impact of the hardness and brittleness of ionic compounds on their applications.
the ions in ionic solids are held in a lattice due to the electrostatic forces of attraction in cations and anions as well as the repulsion with the like charges
