Everything around us is made up of different elements. The air has Oxygen and Nitrogen. Plants and people have lots of Carbon. Helium is in balloons. Hydrogen is in water. Open the Symbol screen, then explore to develop your own ideas about how the atomic particles determine the name of an atom or ion. Explain your understanding: 5. What determines the element

Due to protons and electrons number.

Explanation:

The atomic particles determine the name of an atom or ion by number of protons because the number of protons determines the atomic number of an element and this atomic number distinguishes one element from another and number of electrons also be different in atoms of the same element due to chemical bonding, due to which ions are produced. So we can say that atomic particles such as proton, electron and neutrons determine the name of an atom or ion.

the density of gold = 19.3 g/cm3

the relation between density and mass and volume is

density = mass / volume

given :

mass of gold = 13 g

density = 13g / volume = 19.3

volume = 13 /19.3 = 0.67 cm^3

thus volume of gold nugget = 0.67 cm^3

i wish i could but this one is weird give me abc and i can solve it.
