Answer:
halogen
Explanation:
Group VIIA/halogen/ is the only group in periodic table in which all the elements are nonmetals. This group contains F, Cl, Br, I, and At. <em>Halogen</em> meaning salt producer.

Answer:
6.022 x 10²³
Explanation:
Data Given:
mass of carbon = 12.01 g
individual particles = 6.02 x 10²³
number of atoms = ?
Solution:
Formula used to find the number of atoms
no. of moles = number of atoms / 6.022 x 10²³ . . . . . (1)
So, first we have to find number of moles
Formula to find no. of moles
no. of moles = mass in grams/ molar mass. . . . . (2)
molar mass of Carbon = 12.01 g/mol
Put values in eq.2
no. of moles = 12.01 g / 12.01 g/mol
no. of moles = 1 mol
Now put the values in eq. 1
no. of moles = number of atoms / 6.022 x 10²³ . . . . . (1)
1 mol = number of atoms / 6.022 x 10²³
Rearrange the above equation
number of atoms = 1 mol x 6.022 x 10²³
number of atoms = 6.022 x 10²³
So it is 6.022 x 10²³ atoms in 12.01 grams of carbon. This 6.022 x 10²³ also Known as Avogadro's number that is one mole of any substance consists this number of atoms.
