What is the symbol for 2 electrons and 2 protons?
Number protons equal to atomic number. So the element is Helium
How many protons are in a ion with 86 electrons and a -1 charge?
A neutral atom has an equal number of protons and electrons. Protons are positively charged, and electrons are negatively charged. Therefore if you have an ion with a -1 charge, it has one extra electron. So your ion has 85 protons.
How can you use the periodic table to find the number of protons in one atom of an element?
valence electrons is the same as the number as the last digit in the group :)
Why must a positively charged body have a deficiency of protons?
It doesn't. A positively charged body is deficient in electrons. In an uncharged object there are equal numbers of positively charged protons and negatively charged electrons. Removing electrons will leave more protons than electrons, so the object will be positively charged. Such an object is said to have a deficiency or electrons rather than a surplus of electrons because it is generally easier to remove electrons than it is to add protons. Electrons occupy the outer shells of an atom and have a much lower mass than protons. The protons, by contrast, are bound together in the dense nucleus.
How many protons and electrons in ion Br?
35 protons, 36 electrons
What do electrons have that protons always have in equal magnitude?
Electrons have negative charge and protons have positive charge. These charges always have equal magnitude but opposite signs in an atom, maintaining electrical neutrality.
What particles have negative electric charges equal to the positive charges of the protons?
The electrons; their negativity cancels out the protons' positivity so the atom is electrically neutral.
What parts of an atom are equal to each other?
It depends on what you mean by what parts are equal. Protons and electrons both have the same magnitude of charge with opposite signs and electrons are much less massive than protons. Protons and neutrons are approximately equal in mass but protons have a charge of +e Coulombs while neutrons have a charge of 0. Atoms can often exist with unequal numbers of protons and electrons. Such atoms are called ions and have a negative charge if they have more electrons than protons and positive charge if they have more protons than electrons.
Protons have magnitude of charge as neutron but opposite in sign?
Protons have charge while neutrons do not. Hence, "neu-" like neutral? Electrons carry a negative charge while protons carry a positive charge.
What must be equal in a neutral atom?
Protons and electrons must be equal in a neutral atom because protons and electrons have equal but opposite charges.
Is the number of protons no of electrons?
Yes , the no. of electrons is equal to the no. of protons
If an atom contains 15 electrons it will also have 15?
Protons, because electrons are equal to the atomic number and protons are equal to the number of electrons.
When atoms are at rest what do they have an equal number of?
protons and electrons protons and electrons
How do protons and electrons differ in their electronic charge?
Protons and electrons have equal and opposite charge of the Elementary charge e, with protons being e+ and electrons e-
How many electrons versus protons in an atom?
The number of electrons should = the number of protons.
Do protons and electrons have the same number?
Yes, the atomic number is equal to the number of protons. The number of protons is also equal to the number of electrons
Nobelium has an atomic number of 102 how many protons and electrons does it have?
Nobelium has 102 protons and 102 electrons, as the number of protons is equal to the atomic number, and in a neutral atom, the number of protons is equal to the number of electrons.
