What else can I help you with?
How do you infer that an atom is electrically neutral or an ion by referring to its number of electrons?
if number of electron and protons are equal(except for H,as it has no proton,so it shoulh has one electron to be electrically neutral).
How do you find the number of electrons in an electrically neutral atom for calcium?
To find this out, it's really easy. Simply look on a periodic table for the proton number of the element in question. In this case, Ca = 20. Protons are positively charged and electrons are negatively charged. Therefore, in an electrically- neutral Ca atom, there are 20 electrons.
Why number of electron are equal to the number of proton?
because an atom is electrically neutral
What will an electrically neutral atom have equal numbers of?
An electrically neutral atom has the same number of electrons as protons. Since protons have a positive change and electrons have a negative charge, when there is the same number of them, the charges cancel each other out. Example: Helium is neutral when it has 2 electrons, since it also has 2 protons.
In a atom is the electron number the same proton number?
Yes, provided the atom is electrically neutral.
Why atom is electrical nutral?
An atom is electrically neutral because it contains an equal number of positively charged protons in the nucleus and negatively charged electrons orbiting around the nucleus. The positive charge of the protons cancels out the negative charge of the electrons, resulting in an overall neutral charge for the atom.
Does the number of protons have to equal the number of electrons to keep it electrically neutral?
Yes: each electron has a total charge of -1 and each proton has a total charge of +1. In order for them all to cancel out (thus making the substance neutral), the number of protons and electrons must be equal.
Why is the atom electrically neutral?
it is neutral because there are the same numbers of protons and electrons in an atom so the positive charge of the proton balances out the negative charge of an electron
How many protons are there in a neutral atom with thirteen electrons?
13. Both have same charge except electron has negative and proton positive. Neutrons are electrically neutral
1 In an electrically neutral atom the number of protons in the nucleus is equal to the number of?
In an atom, the number of electrons is equal to the number of protons in the nucleus of the atom. This only varies in ions, where electrons have been added to an atom or removed to create a full outer shell.
Is an atoms number of protons is always the same as its number of valence electrons?
For neutral atoms, the electron number is always the same as the proton number.For ions, charged atoms, the proton number is different than the electron number by the charge (e.g. a hydrogen ion, H(+1) has 1 proton and 0 electrons, 1 more proton than electrons).
Is most atoms have more electrons than proton false or true?
False. In a neutral atom, the number of electrons is equal to the number of protons. This balance between positively charged protons and negatively charged electrons is what keeps the atom electrically neutral.
