How many protons, neutrons and electrons does a lithium atom have?

• p=3 n=4 e=3
• p=3 n=7 e=3
• p=3 n=4 e=4

The nucleus of an atom

• is positively charged

• is negatively charged

• has no charged particles

• has both positively and negatively charged particles

Electrons are found

• in the nucleus

• outside the nucleus

• both in and outside the nucleus

An atom is neutral because

• the positive charge of the nucleus is equal to the sum of the negative charges of the electrons

• the negative charge of the nucleus is equal to the sum of the positive charges of the electrons

• it does not contain any charged particles
