How can you determine the number of valence electrons for an element by looking at its Bohr diagram?

To find valence electrons from a Bohr diagram, simply count the electrons in the outermost shell

  1. What is the primary advantage of using the metric system for scientific measurements compared to other systems?

The primary advantage of the metric system in science is its decimal base (powers of 10), which allows for simple conversions and calculations,

What is the maximum number of electrons that can be held in the first, second, and third principal energy levels (shells), according to the Bohr model rules?

According to Bohr model rules, the maximum electrons for the first, second, and third energy levels (n=1, 2, 3) are 2, 8, and 18,

whats the astehnosphere

The semi-fluid layer of the mantle beneath the lithosphere, allowing plates to move.

When converting a measurement from a smaller metric unit (like millimeters) to a larger metric unit (like meters), in which direction does the decimal point move

When converting from a smaller metric unit (like millimeters) to a larger one (like meters), the decimal point moves to the left,

  • Define an isotope. What is the key difference in the composition of two different isotopes of the same element?

An isotope is a form of an element where atoms have the same number of protons but a different number of neutrons, leading to different atomic masses. The key difference is the neutron count

whats is Convection Currents

 Heat from the Earth's core creates currents in the mantle that drag the plates.

  • A chemical reaction produces 30 milligrams (mg) of a precipitate. What is the mass of the precipitate in grams (g)?

The mass of the precipitate in grams is 0.030 g.

how do we determine whether an element will lose or gain electrons while bonding 

the element will either lose or gain the smallest amount of Ve-

What is the Noble Gas Configuration for Indium (In)

[Kr]5s24d105p1

  • How is the atomic number different from the mass number? Which one is used to identify an element, and which one can vary among isotopes?

The atomic number (Z) is different from the mass number (A) as the atomic number represents the number of protons only, while the mass number is the sum of both protons and neutrons.

400

whats convergent 

Plates collide, leading to subduction (one plate slides under another) or continental collision (forming mountains like Everest).

  • How are Boyle's Law, Charles' Law, and Gay-Lussac's Law combined to form the Ideal Gas Law?

Boyle's, Charles's, and Gay-Lussac's laws describe relationships between pressure (P), volume (V), and temperature (T) for gases, and are combined by incorporating Avogadro's Law

what is Divergent

Plates pull apart, creating new crust at mid-ocean ridges (like the Mid-Atlantic Ridge) or rift valleys (like the East African Rift)
