Hydrogen has an atomic number of 1. How many neutrons and protons are in a hydrogen-3 isotope?
a. O neutrons, 3 protons
b. 1 neutron, 2 protons
C. 2 neutrons, 1 proton
d. 3 neutrons, 0 protons

Hello there,

In a hydrogen the neutrons and protons are as follows:

Now with a hydrogen with a -3 isotope:

A hydrogen with a -3 isotope would have 1 proton and 2 neutrons.

Hope I helped,

each chemical family is represented as a group or column on the periodic table. based on chemical properties, there are 6 types of chemical families. group 1 represents alkali metals, group 2 represents alkaline earth metals, groups 3 to 12 represent transition metals, groups 13 to 16 represent non-metals and other metals, group 17 represents halogens and group 18 represents noble gases.

hey there!

mass = 6.75 g

volume =   9 cm³

therefore:

d = mass / volume

d   = 6.75 / 9

d = 0.7 g/cm³
