I need simple answers that a 14-year-old would understand.
Nana76 [90]

Answer:

1. The Nummber of electrons present in the outermost shell is called Valence electrons.

2. Thomson model:

Thomson model of atom is the model which states that electrons are embedded in a positively charged solid material which is spherical in shape.

Rutherford model

Rutherford model of atom is the model which explains that there is a nucleus in the center of the atom and electrons are located around the nucleus.

3. Relative atomic mass. Atoms have very little mass , so they're difficult to measure accurately. Instead, chemists use a scale. On this scale the mass of a 12C atom is exactly 12.

4. Difference between Alpha, Beta and Gamma radioactive decay:

Alpha decay forms new element with two fewer protons and two fewer neutrons;

Beta decay forms new element with one more proton and one fewer neutron.

Gamma decay forms NO new element, but now the element has less energy because energy is released as gamma rays.

Gamma radiation has the highest penetration power, Beta decay goes the second, alpha decay the last. However, alpha particles make the most damage even if it has the lowest penetration power among the three.

5. This species has a 2− charge on it, so it is an anion. Anions are named using the stem of the element name with the suffix -ide added. This is the oxide anion.

230g sample of a compound contains 136.6g carbon, 26.4g hydrogen, and 31.8g nitrogen. What is masspercentif oxygen
natulia [17]

Answer:

15.3 %

Explanation:

Step 1: Given data

  • Mass of the sample (ms): 230 g
  • Mass of carbon (mC); 136.6 g
  • Mass of hydrogen (mH): 26.4 g
  • Mass of nitrogen (mN): 31.8 g

Step 2: Calculate the mass of oxygen (mO)

The mass of the sample is equal to the sum of the masses of all the elements.

ms = mC + mH + mN + mO

mO = ms - mC - mH - mN

mO = 230 g - 136.6 g - 26.4 g - 31.8 g

mO = 35.2 g

Step 3: Calculate the mass percent of oxygen

%O = (mO / ms) × 100% = (35.2 g / 230 g) × 100% = 15.3 %

Silver has a density of 10.5 grams/cm3. What would be the mass of a 5 cm3 piece of sliver
enyata [817]

Answer:

52.5 g

Explanation:

Density= mass/volume

Rearranging the equation gives us m= d(V)

m= d(V)

m= (10.5 grams/cm^3)(5 cm^3)

m= 52.5 g
