This is much more simple than it sounds...
s has 1 orbital; p = 3 orbitals; d= 5 orbitals; f= 7 orbitals. (you just need to memorize this)
A maximum of 2 electrons can occupy each orbital.
<span>The number of orbitals that each atom has is based on the number of electrons it has and by consequence it's position on the periodic table. </span>
The orbitals occur in sequence. Whereby electrons fill first from the lowest energy level (1s) outwards to the highest.
3p = the following sequence.
1s, 2s, 2p, 3s, 3p: these 'sets' can hold the following electrons respectively (2+2+6+2+6) 18 which corresponds with argon on the periodic table. REMEMBER p has 3 orbitals, d has 5 orbitals. So, here there are 9 orbitals.
The sequence through n=4 is:
<span>1s, 2s, 2p, 3s, 3p, 3d, 4s, 4p, 4d, 4f

One mole of a substance is equal to 6.022 × 10²³ units of that substance (such as atoms, molecules, or ions). The number 6.022 × 10²³ is known as Avogadro's number or Avogadro's constant. The concept of the mole can be used to convert between mass and number of particles.
Answer:
Moles: 
Molar mass: 
Explanation:
Hello,
In this case, we can use the ideal gas equation to compute the moles of the gas sample as shown below:
Thus, we should use the pressure in atm as follows:
Moreover, the molar mass is obtained by dividing the given mass by the obtained moles:
Best regards.
Answer:
Alginates are added to help protect the lining of the gullet (oesophagus) from stomach acid. Alginates include sodium alginate and alginic acid. They are present in antacid medications with various brand names.
