Question

1. give the symbol and number of electrons in a neutral atom of:

element symbol electrons
uranium
chlorine
boron
iodine
antimony
argon

1. name the element which has the following numbers of particles. be specific. (include charges and mass numbers where possible.) 26 electrons, 29 neutrons, 26 protons 53 protons, 74 neutrons

Explanation:

Step1: Recall element symbols

Uranium - U, Chlorine - Cl, Boron - B, Iodine - I, Antimony - Sb, Argon - Ar.

Step2: Use atomic number = electrons in neutral atom

Uranium (atomic number 92) - 92 electrons, Chlorine (17) - 17 electrons, Boron (5) - 5 electrons, Iodine (53) - 53 electrons, Antimony (51) - 51 electrons, Argon (18) - 18 electrons.

Answer:

Element	symbol	electrons
Chlorine	Cl	17
Boron	B	5
Iodine	I	53
Antimony	Sb	51
Argon	Ar	18
