Does an element's number of valence electrons equals the element's number of protons?
Only hydrogen and helium have the stated property. For all heavier elements than these two, the number of valence electrons is less than the total number of electrons, which must be the same as the number of protons in all neutral atoms.
What are the differences between neon and helium?
Neon has 8 more protons and 8 more electrons than helium. It's heavier, but still lighter than air.
Do protons and Electrons have about the same mass?
No. Protons have about 1836 times the mass of an electron.
When an atom has more electrons than protons it is?
An atom with more protons than electrons is a cation.
Are neutrons smaller than protons?
no, they both have the same relative mass, this is why you add the number of protons and neutrons to get the mass number for the atom. The neutron is very slightly more massive than proton, by about the mass of an electron.
Why do protons and electrons aproximately equal a atomic mass?
Protons are much heavier (1800 X approx) than electrons! Atomic mass is due to the mass of the protons and neutrons only a very small % of atomic mass is due to electrons.
Are protons and electrons equal in magnitude?
No, A proton is 1836 times heavier than that of electron.So they are not equql in magnitude
Does Anions have more protons than electrons?
anions have more electrons than protons
Are electrons bigger than protons neutrons?
No they're smaller than protons and electrons

Only hydrogen and helium have the stated property. For all heavier elements than these two, the number of valence electrons is less than the total number of electrons, which must be the same as the number of protons in all neutral atoms.
Are there the same amount of protons as there are of electrons in and atom?
NoYes. A neutral atom will have the same number of protons and electrons.
Are electrons bigger than neutrons and protons?
Electrons are 1,836 times lighter than protons. A proton is 99.8% the mass of a neutron
What keeps electrons close to te nucleus?
Electrons are not shot off because the e- (which are negative) have an electromagnetic force hold with the protons (positive) in the centre. This attraction is also because of gravity and the force of attraction (as protons/neutrons are significantly heavier than electrons) it creates.
What has more electrons than protons?
A positive ion.
Are electrons larger than neutrons and protons?
no. protons and neutrons are MUCH larger than electrons.
Are electrons protons or neutrons the smallest particles if not what arew?
protons/neutrons are made of quarks which are smaller than electrons. electrons are smaller than protons and neutrons.
What kind of charges do protons and electrons have?
Protons have positive charge, electrons have negative charge, and neutrons have no charge. The heavier particles, protons and neutrons, make up the atomic nucleus, which always has a positive charge.
