What else can I help you with?
An atom with more electrons would have charge?
An atom with more protons than electrons will have a positive charge. Neutral atoms can loose electrons if they are subjected to some kind of energy. Sometimed illumination with the correct color of light is sufficient to knock electrons off atoms.
What happens to the amino and carboxyl groups at normal cellular pH of ca. 7?
At a normal cellular pH of around 7, the amino group will be protonated (-NH3+) and the carboxyl group will be deprotonated (-COO-). This is because the pKa of the carboxyl group is around 2, making it more likely to lose a proton, while the pKa of the amino group is around 9, making it more likely to gain a proton at pH 7. This results in the formation of a zwitterion, where the amino group carries a positive charge and the carboxyl group carries a negative charge.
If you have a lower pH will you have higher proton concentration?
Yes, a lower pH indicates a higher proton concentration because pH is a measure of the concentration of hydrogen ions in a solution. A lower pH means more hydrogen ions are present, leading to a more acidic environment.
What makes up the nucleus of the atom?
There are only two stable subatomic particles, Protons and Neutrons. Protons: Positive charge, 1amu The "atomic number" of an element gives the number of protons in its nucleus. Neutrons: No charge, makes up rest of the atomic mass, 1amu each The nucleus of every element contains one or more of each kind of stable subatomic particle, except for hydrogen which has ONE proton, but no neutrons
What molecules have an uneven charge with more negative charge on the side and more positive charge on the other?
Polar molecules such as water (H2O) have an uneven charge distribution, with the oxygen atom being more electronegative and carrying a partial negative charge, while the hydrogen atoms carry partial positive charges. Additionally, molecules like ammonia (NH3) and hydrogen chloride (HCl) can also exhibit this uneven charge distribution due to differences in electronegativity between the atoms.
What has a mass slightly less than that of a neutron?
A proton has a mass slightly less than that of a neutron. A neutron is slightly more massive due to the extra mass of an additional electron.
What is the charge of a proton?
With relation to an electron the proton has a charge of -1, since the proton's charge is opposite of the electron's. However, the common notation of charge is relative to a proton's- therefore, it is more accurate to leave things in terms of a proton's charge. In terms of proton charge, a proton has a charge of +1.
What is the relative charge of proton?
A proton has an absolute charge of + 1.6 x 10-19 coulombs.
What is difference between proton and positive charge?
There is no difference, they are one the same. A proton has a positive charge and a positive charge is a proton. Of course with the positive charge, it's simply having more protons than electrons.
What kind of charge does an object with more proton's than electrons have?
It has a positive charge.
Which is slight more massive then a proton?
Neutrons contain slightly more mass.
How does the mass of the neutron compare with the mass of the proton?
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 mass of a neutron and a proton are 1.67492729(28)×10−27 kilograms and 1.672621637(83)×10−27 kilograms respectively. That makes the neutron about 25/10,000ths more massive than the proton.
What mass do neutrons have?
Slightly more than that of a proton plus an electron.
Which particle has a close mass to proton?
The neutron, which is slightly more massive. The neutron is composed up two down quarks and one up quark (charges of -1/3 and 2/3 [in terms of proton charge], respectively) and the proton is composed of one down quark and two up quarks.
The part of the atom that has a positive charge is a?
This particle is the proton.
Which has more mass-a proton or electron?
The proton has much more mass than the electron, by a factor of 1836 times, a ratio called "mu". Recent astronomical research suggests mu may have changed by 20 parts per million in the last 12 billion years, but I plan to wait at least a billion years for confirmation!
Do protons and electrons have the same amount of electrical charge and have the same mass?
Each proton has a positive charge. Each electron has a negative charge. The 'size' of the charge on every proton and every electron is the same. Every proton has the mass of about 1,850 electrons.
