Html viewer was selected to open .htm files and that would not handle mailto: and other links. This app reset that and then next time I opened the file it asked what app to use and I could select Browser (or Chrome). Perfect. At times, I want to use Chrome to open an .html file that I put on my tablet.
Neutrons have a mass of 1.675 Ã 10-24g, which is a little heavier than the proton. Neutrons are 1839 times heavier than electrons. Like all hadrons, neutrons are made of quarks. A neutron is made of two down quarks and one up quark. One up quark has a charge of +2/3, and the two down quarks each have a charge of -1/3.
The mass of a neutron is slightly greater than the mass of a proton. The neutron has no electric charge while the proton has a positive charge (+1 elementary charge). The ma â¦ ss of a neutron and a proton are 1.67492729(28)Ã10â27 kilograms and 1.672621637(83)Ã10â27 kilograms respectively.he mass of the neutron is 1.67493 x 10-27 kg. The elementary charge is equal to 1.60218 x 10-19 Coulombs. The proton and electron each carry this charge, but the sign of the charge will be positive for the proton, and negative for the electron.
