Is an object's net charge positive or negative if it loses electrons?
positive
Why do electrons move the negative end of the tube to the positive end?
Why do electrons move the negative end of the tube to the positive end
What does it mean when an object has a positive charge?
When an object has a positive charge, it has a deficiency of electrons.
Which particles in atoms have a positive charge?
electrons
If an object has a positive charge what has it done?
It has lost electrons, resulting in a more positive charge.
Which scientists envisioned the atom as a ball of positive charge with electrons embedded in it?
D.thomson ;)
What did Thomson call electrons?
Thomson believed about atoms, that : An atom consists of a sphere of positive charge with negatively charged electrons embedded in it. Positive and negative charges in an atom are equal in magnitude, thus an atom is electrically neutral and it has no overall + or - charge.
Which model of the atom illustrated that an atom was a cloud of an positive charge with electrons randomly embedded within it?
The plum pudding model by JJ Thomson.
How is negative charge distributed in the atom according to Thomson's model?
Just as seeds in a watermelon electrons are embedded in a positive ball
When electrons were discovered scientist inferred that neutral atoms contain positive charges because?
Scientists inferred that nuetral atoms contained postitive charges, because electrons contained negative charges.
How did Thomson demonstrate the existence ofthe electron?
Thomson discovered electrons studying cathode rays and estimating the mass and electrical charge of the component particles.
Does electrons have positive charge?
No, electrons are negative. Protons are positive, and neutrons are neutral.
What can be a negative for electrons or a positive for protons?
The charge of electrons is negative and of protons is positive.
What charges do proton an electrons have?
Pprotons have a positive charge neutrons have no charge and electrons have a negative charge. However the one with the smallest mass is electrons.
Does boron become positive or negative when it loses electrons?
All atoms become positive ions when they lose electrons, and negative when they gain electrons.
Describe the plum-pudding model of the atom?
A Description of electrons scattered inside the atom
If an atom that loses electrons is it positive or negative?
It will be positive.
